Steal My Bitcoin CTF PoC

A researcher has published a proof-of-concept exploit for the "Steal My Bitcoin" CTF challenge that exploits PHP memory handling vulnerabilities to achieve remote code execution. The attack uses crafted multipart uploads to trigger out-of-memory conditions in PHP workers, leaking heap and code addresses through session cookies, then forges a PHP structure to execute arbitrary system commands. The complete exploit is demonstrated in a single Python script using only standard libraries and requires at most 20 HTTP requests to execute successfully.
