What to do
AI-suggested
1. Immediate patching: Organizations should upgrade Badaso CMS to a version where this vulnerability is fixed once available. Until then, consider disabling the Media Manager's file upload functionality if not essential. 2. Implement strict file upload validation: Enforce server-side checks to validate file types and contents beyond MIME types, including scanning for embedded PHP or other executable code within uploaded files. 3. Restrict file execution permissions: Configure web server settings to prevent execution of uploaded files in directories intended for media storage, e.g., by disabling PHP execution in upload directories via .htaccess or equivalent configurations. 4. Enforce least privilege: Limit authenticated user roles that can upload files to trusted personnel only, and monitor upload activities for anomalies. 5. Network segmentation and monitoring: Isolate CMS servers and monitor logs for suspicious file uploads or access patterns. 6. Employ Web Application Firewalls (WAFs): Use WAF rules to detect and block attempts to upload or access malicious files. 7. Conduct regular security audits and penetration testing focusing on file upload functionalities to detect similar weaknesses.
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.
