CVE-2024-24550Public exploitNetwork attack vector

Authenticated code execution via unchecked File API upload

Published Jun 24, 2024 · Updated Aug 1, 2024

Unrestricted file upload in the Bludit File API 3.14.0 through 3.15.0 allows remote authenticated users to execute server-side code. The uploadFile method moves an attacker-supplied filename and temporary upload into a web-accessible page directory without checking its extension or MIME type. Exploitation requires the API to be enabled, which is disabled by default, and a valid API token; a PHP web shell then runs with the web server's privileges.
