CVE-2025-52353CVE-2025-52353
Description
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.
