CVE-2024-39171Public exploitNetwork attack vector

Unauthenticated code execution via upload path traversal

Published Jul 9, 2024 · Updated Jul 9, 2026

Path traversal in PHPVibe 11.0.3 through 11.0.46 allows remote attackers to execute code through crafted upload requests. The upload-ffmpeg.php, upload-mp3.php, and upload.php handlers place an unfiltered token value into the fopen path, enabling traversal to overwrite the web-root .htaccess and place PHP code in a .png file. No authentication or user interaction is required; execution depends on Apache honoring the overwritten rewrite rules and parsing the uploaded image as PHP.
