OpenSSH 安全漏洞
(CVE-2024-6387)
描述：OpenSSH（OpenBSD Secure Shell）是加拿大OpenBSD计划组的一套用于安全访问远程计算机的连接工具。该工具是SSH协议的开源实现，支持对所有的传输进行加密，可有效阻止窃听、连接劫持以及其他网络级的攻击。 OpenSSH 存在安全漏洞，该漏洞源于信号处理程序中存在竞争条件，攻击者利用该漏洞可以在无需认证的情况下远程执行任意代码并获得系统控制权。
描述
CVE-2024-6387 (regreSSHion) Exploit (PoC), a vulnerability in OpenSSH's server (sshd) on glibc-based Linux systems.
介绍
# regreSSHion Exploit (PoC)
## Description
This repository contains an exploit targeting CVE-2024-6387 (regreSSHion), a vulnerability in OpenSSH's server (sshd) on glibc-based Linux systems. It exploits a race condition in the signal handler of OpenSSH, potentially leading to remote code execution as root.
## Requirements
- Linux system with glibc-based OpenSSH server (tested on Ubuntu, Debian).
- `gcc` compiler installed.
- Basic understanding of compiling and running C programs.
- Permission to test or use such exploits on authorized systems only.
## Usage
1. **Compile the Exploit:**
```bash
gcc -o regreSSHion exploit.c -lpthread
```
2. **Run the Exploit:**
```bash
./regreSSHion <target_ip> <target_port>
```
Replace `<target_ip>` and `<target_port>` with the IP address and port of the vulnerable OpenSSH server.
3. **Interpret Output:**
- Monitor the terminal for exploitation attempts and feedback.
- Adjust timing parameters or shellcode as necessary for successful exploitation.
## Shellcode Customization
You can customize the shellcode in the *exploit.c* file to execute different payloads or commands on the target system. The provided shellcode is a basic example that spawns a `/bin/sh` shell. Modify the `shellcode[]` array to suit your specific requirements.
