# CVE-2023-36899.NET 身份绕过 IIS 认证
|
|
||||||
|
|
||||||
默认情况下.NET 会话产生的 SessionID 一般位于 HTTP 报文请求或者响应的 Cookie 字段，
|
|
||||||
命名方式如下
|
|
||||||
`Cookie:ASP.NET_SessionId=uxfzmc552rdiwh45ja2t3vud;`
|
|
||||||
|
|
||||||
如果不想用上述的 Cookie 存储方式也可以改成 Cookie 不带 SessionID 这样的会话，只需要在 web.config 配置<SessionState>节点属性 cookieless 属性为 true，这样.NET 将会话 ID 随着 HTTP 请求附加到 URL 地址上。配置清单如下
|
|
||||||
```xml
|
|
||||||
<system.web>
|
|
||||||
<sessionState cookieless="true"/>
|
|
||||||
</system.web>
|
|
||||||
```
|
|
||||||
这样配置后 Cookie 作为 URL 地址的一部分，会话 SessionID 值都以明文的形式发送显然
|
|
||||||
是不安全的。如下图
|
|
||||||
但是在早期基于.NET Framwork 版本的应用中大量存在这样的场景，然而这种特性也会存
|
|
||||||
在绕过 IIS 身份验证的风险。以下通过实验演示绕过 IIS 身份验证的漏洞场景。
|
|
||||||
在 IIS 项目中 Windows 身份验证是一种强大且广泛使用的身份验证方法，需要匿名访问的
|
|
||||||
用户输入正确的 Windows 本地帐户登录后才能访问该 Web 应用。配置 Windows 身份验证
|
|
||||||
步骤如下：
|
|
||||||
1. 启用 Windows 身份验证安全功能
|
|
||||||
2. 打开 IIS10 选择 Uploads 目录后进入身份验证模块，启用 Windows 身份验证
|
|
||||||
配置完成后访问 /(S(mwdwx5uhl2yqliv2w45c5cla))/uploads/dynamicCompilerSpy.aspx
|
|
||||||
弹出授权登录对话框如下图
|
|
||||||
遇到这种需要本地 Windows 账户登录才能访问，一般攻击在打点时遇到这样 WebShell 上
|
|
||||||
传后的场景还是比较常见的，以前可能就放弃或者找其他的解决办法，现在可以用 URL 会
|
|
||||||
话 ID 的方式绕过，
|
|
||||||
3. 常用的 Bypass Payload 如下
|
|
||||||
`(S(mwdwx5uhl2yqliv2w45c5cla))/up/(S(mwdwx5uhl2yqliv2w45c5cla))loads/
|
|
||||||
`
|
|
||||||
|
|
||||||
输入两次会话 ID，并且拆解了 uploads 目录，这对绕过 WAF 等安全防护也是有用的。请求
|
|
||||||
`http://192.168.101.77/(S(mwdwx5uhl2yqliv2w45c5cla))/up/(S(mwdwx5uhl2yqliv2w45c5cla))loads/dynamicCompilerSpy.aspx`

# CVE-2023-37582_EXPLOIT
|
|
||||||
Apache RocketMQ Arbitrary File Write Vulnerability Exploit Demo
|
|
||||||
|
|
||||||
# Overview
|
|
||||||
In fact, the Arbitrary file write vulnerability(CVE-2023-37582) in Apache RocketMQ has already been addressed in the CVE-2023-33246 RCE vulnerability.
|
|
||||||
However, the fix provided for [CVE-2023-33246](https://github.com/Malayke/CVE-2023-33246_RocketMQ_RCE_EXPLOIT) RCE is not comprehensive as it only resolves the impact on RocketMQ's broker.
|
|
||||||
This vulnerability affects RocketMQ's nameserver, and exploiting it allows for arbitrary file write capabilities.
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
# Setup local RocketMQ environment via Docker
|
|
||||||
```bash
|
|
||||||
|
|
||||||
# start name server
|
|
||||||
docker run -d --name rmqnamesrv -p 9876:9876 apache/rocketmq:4.9.6 sh mqnamesrv
|
|
||||||
|
|
||||||
# start broker
|
|
||||||
docker run -d --name rmqbroker \
|
|
||||||
--link rmqnamesrv:namesrv \
|
|
||||||
-e "NAMESRV_ADDR=namesrv:9876" \
|

# Exploit
|
|
||||||
|
|
||||||
It is important to note that the exploit provided is for demonstration purposes only.
|
|
||||||
The current exploit allows for the writing of a file to the nameserver's `/tmp/pwned` directory.
|
|
||||||
Modifying the content of the `body` variable allows for the exploitation of this vulnerability by writing an OpenSSH private key or adding a cronjob.
|
|
||||||
However, it is crucial to remember that such activities are unauthorized and can lead to serious security breaches.
|
|
||||||
It is strongly advised to refrain from engaging in any malicious activities and to prioritize responsible and ethical cybersecurity practices.

|
|
||||||
You can use this code to verify if your device supports default IP-in-IP
|
|
||||||
encapsulation from arbitrary sources to arbitrary destinations. The intended
|
|
||||||
use of this code requires at least two more devices with distinct IP
|
|
||||||
addresses for these two devices. The testing in "bypass" mode requires
|
|
||||||
the vulnerable device to be "dual-homed" so routing to the "inside"
|
|
||||||
network from an external network interface can be verified.
|
|
||||||
|
|
||||||
Spoof mode:
|
|
||||||
|
|
||||||
|
|
||||||
The demonstration script can be used in two ways - spoof mode and
|
|
||||||
bypass mode. Initial setup requires at least three devices for this
|
|
||||||
testing. In the simple spoofing mode, attacker will send a IP-in-IP
|
|
||||||
packet from their device to a vulnerable machine
|
|
||||||
(VULNERABLE_MACHINE_IP sys.argv[1]) to replay a packet to the victim's
|
|
||||||
device (VICTIM_IP sys.argv[2]). This mode demonstrates a DDOS
|
|
||||||
capability to send unsolicited traffic to VICTIM_IP. Because this
|
|
||||||
packet has valid source and destination, anti-spoofing measure such as
|
|
||||||
BCP-38 will not block this crafted packet. The intended traffic can be
|
|
||||||
routed through the VULNERABLE_IP to the VICTIM_IP device by an
|
|
||||||
unauthenticated attacker.
|
|
||||||
|
|
||||||
Bypass mode:
|
|
||||||
|
|
||||||
|
|
||||||
In the bypass mode (using all 4 arguments for the script), the
|
|
||||||
attacker will send a crafted IP-in-IP packet from the attacker's
|
|
||||||
device to a vulnerable device (VULNERABLE_MACHINE_IP sys.argv[1]). The
|
|
||||||
vulnerable device will receive and decapsulate the packet and forward
|
|
||||||
the inner IP packet to the victim device (VICTIM_IP sys.argv[2])
|
|
||||||
machine with a source IP Address of DATA_COLLECT_IP (sys.argv[3]). The
|
|
||||||
attacker can thus solicit information using the sample SNMP query to
|
|
||||||
be sent to DATA_COLLECT_IP which he has access to. In the provided
|
|
||||||
example, device at the VICTIM_IP address is assumed to have SNMP
|
|
||||||
enabled with the standard "public" community string for read-only
|
|
||||||
access. SNMP is being demonstrated here, but this forwarding behavior
|
|
||||||
can allow for many types of unexpected IP traffic to traverse using
|
|
||||||
the vulnerable machine as a forwarding point for any nefarious
|
|
||||||
communications as planned by the attacker.

# cve-2021-22908
|
|
||||||
|
|
||||||
This python3 script checks for Pulse Connect Secure servers vulnerable to
|
|
||||||
[VU#667933](https://www.kb.cert.org/vuls/id/667933) CVE-2021-22908. The python requests library is required for operation.
|
|
||||||
|
|
||||||
## Usage modes:
|
|
||||||
`cve-2021-22908.py <host>`
|
|
||||||
This mode will interactively log in to a PCS server to obtain a DSID value.
|
|
||||||
|
|
||||||
`cve-2021-22908.py <host> -d <DSID>`
|
|
||||||
In the case were a PCS user's DSID is already known, this mode will skip the
|
|
||||||
interactive login exchange.
|
|
||||||
|
|
||||||
`cve-2021-22908.py <host> -n`
|
|
||||||
If you do not have authentication available for the target PCS, you can check
|
|
||||||
for only the presence of the Workaround-2105.xml mitigation.
|
|
||||||
|
|
||||||
|
|
||||||
## Results:
|
|
||||||
`HTTP 500`
|
|
||||||
This is indicative of a vulnerable PCS server, due to a crashing CGI.
|
|
||||||
|
|
||||||
`HTTP 403. XML workaround applied`
|
|
||||||
This is indicative of a PCS server that has an XML mitigation applied.
|
|
||||||
|
|
||||||
`HTTP 200. Windows File Access Policies prevents exploitation.`
|
|
||||||
This is indicative of a PCS server that has "Windows File Access Policies"
|
|
||||||
configured in a way that prevents exploitation.
|
|
||||||
|
|
||||||
`HTTP %s. Not vulnerable.`
|
|
||||||
The PCS server does not appear to be vulnerable.

|
|
||||||
|
|

## PackageKit Exploit
|
|
||||||
### Installing Packages
|
|
||||||
`install.py` can be used to install a package (such as gnome-control-center) bypassing authentication on systems vulnerable to CVE-2021-3560
|
|
||||||
|
|
||||||
The package ID will need to include the semicolons so the quotations are necessary. To determine a valid package id, use the included `search.py` script
|
|
||||||
|
|
||||||
On tested systems, simply running the python script results in the process being killed at the correct timing. If needed, you can add a 'time.sleep()' to the end of the script and the sleep & kill technique can be used for better timing.
|
|
||||||
### Usage
|
|
||||||
`python3 install.py 'full;package;id;here'`
|
|
||||||
|
|
||||||
|
|
||||||
### Searching For Package IDs
|
|
||||||
`search.py` is used to determine a full package id from a simple package name.
|
|
||||||
|
|
||||||
### Usage
|
|

`python3 search.py package_name(s)`

## Vulnerability Info
|
|
||||||
https://blog.exodusintel.com/2022/03/10/exploiting-a-use-after-free-in-windows-common-logging-file-system-clfs/
|
|

||||||
## PoC Crasher
|
|
||||||
### Overview
|
|
||||||
The proof-of-concept is very simple, just code to open and close a log file, using `CreateLogFile()` and `CloseHandle()`.
|
|
||||||
|
|
||||||
If the log file `test_log.blf` does NOT exist it will be created.
|
|
||||||
If the log file `test_log.blf` does exist, then the existing file will be opened.
|
|
||||||
|
|
||||||
The file `test_log_crafted.blf` has been modified, such that when opened by `CreateLogFile()`, it will trigger the vulnerability on unpatched systems. The provided proof-of-concept causes a double free when `CloseHandle()` is called, resulting in a BSOD for a BAD_POOL_HEADER.
|
|
||||||
|
|
||||||
### BLF Layout
|
|
||||||
|
|
||||||
The first 0x200 bytes of test_log.blf are the important bytes. Most of these bytes are 0's (as with the rest of a default newly created file), and only matter for the purposes of the checksum.
|
|
||||||
|
|
||||||
These bytes make up a CLFS_RECORD_HEADER and a CLFS_CONTROL_RECORD.
|
|
||||||
|
|
||||||
(Screenshots are taken of the [010 Editor](https://www.sweetscape.com/010editor/))
|
|
||||||
|
|
||||||
#### Crafting the CLFS_CONTROL_RECORD
|
|
||||||
The following fields are changed from the default value of 0 to meet the conditions described in the [referenced blog post](https://blog.exodusintel.com/2022/03/10/exploiting-a-use-after-free-in-windows-common-logging-file-system-clfs/)
|
|
||||||
- `eExtendState` -> 2
|
|
||||||
- `iExtendBlock` -> 2
|
|
||||||
- `iFlushBlock` -> 3
|
|
||||||
- `cNewBlockSectors` -> 3
|
|
||||||
|
|
||||||
After updating these fields, the checksum needs to be updated
|
|
||||||
The result looks like (the changed bytes are colored orange):
|
|
||||||
|
|
||||||
|
|
||||||
##### Checksum Notes
|
|
||||||
The checksum is calculated over the first 0x200 bytes, with the checksum field zeroed out.
|
|
||||||
|
|
||||||
[Alex Ionescu documents](https://github.com/ionescu007/clfs-docs) that the CRC32 polynomial is `0x04C11DB7`.
|
|
||||||
However, after some experimentation with the 010 Editor's CRC32 tool and referencing [Michaelangel007's notes](https://github.com/Michaelangel007/crc32) the checksum can be replicated using the 'reverse' fixed polynomial `0xEDB88320`.
|
|
||||||
(This is the same polynomial, just flipped around from the perspective of 010 Editor's CRC32 implementation.)
