HIGH

Badaso CMS file upload vulnerability

Published August 26, 2025Updated August 26, 2025Source: osv

Summary

An arbitrary code execution vulnerability in Badaso CMS 2.9.11. The Media Manager allows authenticated users to upload files containing embedded PHP code via the file-upload endpoint, bypassing content-type validation. When such a file is accessed via its URL, the server executes the PHP payload, enabling an attacker to run arbitrary system commands and achieve full compromise of the underlying host. This has been demonstrated by embedding a backdoor within a PDF and renaming it with a .php extension.
