AI-analyzed exploit summary This is a Metasploit module that exploits a Zip-Slip vulnerability (CVE-2026-24479) in HUSTOJ versions before v26.01.24, allowing authenticated administrators to achieve remote code execution by uploading a crafted zip file that traverses directories and extracts a malicious PHP payload.
Description
HUSTOF is an open source online judge based on PHP/C++/MySQL/Linux for ACM/ICPC and NOIP training. Prior to version 26.01.24, the problem_import_qduoj.php and problem_import_hoj.php modules fail to properly sanitize filenames within uploaded ZIP archives. Attackers can craft a malicious ZIP file containing files with path traversal sequences (e.g., ../../shell.php). When extracted by the server, this allows writing files to arbitrary locations in the web root, leading to Remote Code Execution (RCE). Version 26.01.24 contains a fix for the issue.
