The Ghost of PHP Past: Analyzing the "New" 5.4.16 Exploit on GitHub

There is a familiar cycle in the infosec world: an old vulnerability is repackaged, uploaded to GitHub, and suddenly the internet panics as if it were a zero-day.

Remote Code Execution (RCE): By injecting arguments such as auto_prepend_file=php://input, an attacker can force PHP to execute arbitrary code provided in the body of an HTTP request, potentially leading to a full system compromise.

This repository contains technical details and a Proof of Concept (PoC) for CVE-2024-5416, a Stored Cross-Site Scripting (XSS) vulnerability affecting the Elementor Website Builder plugin for WordPress (versions up to 3.23.4). The Ghost of PHP Past: Analyzing the "New" 5

1. Path Confusion (CVE-like behavior): The attacker sends a request with a deeply nested path:
   GET /vulnerable-script.php/FOO/BAR/../../../etc/passwd HTTP/1.1
2. Environment Variable Hijack: If cgi.fix_pathinfo=1 is enabled (still common in shared hosting), PHP-FPM misinterprets the request and allows the attacker to inject arbitrary environment variables.
3. Code Injection: Using crafted PHP_VALUE directives, the attacker sets auto_prepend_file to a remote URL or base64-encoded PHP code, leading to RCE.

So, why "new"? Because old vulnerabilities rarely die. They sink into the source code of forgotten forks or reappear in IoT devices. The "new" aspect of the GitHub repositories appearing in late 2024 and early 2025 is not a new vulnerability but rather new weaponization techniques against modern environments running unsupported PHP branches (PHP 7.4, 8.0, or custom builds).
