Executive Summary

This vulnerability in WWBN AVideo allows unauthenticated users to access private playlist contents through the video_from_program API endpoint. The system fails to validate playlist ownership, enabling attackers to enumerate private playlist names, owner details, and video titles, including password-protected content, via simple HTTP GET requests.

Detection Guidance

To detect this vulnerability, check if unauthenticated HTTP GET requests to the /APIName=video_from_program endpoint return private playlist data. Use curl commands like: curl -X GET 'http://<target>/APIName=video_from_program&ID=<playlist_id>' to test for unauthorized access to private content.

Impact Analysis

Attackers could access sensitive information such as private playlist names, owner data, and video titles without authentication. This includes content that is password-protected, potentially exposing confidential or proprietary information. The impact depends on the nature of the playlists and videos stored in the system.

Compliance Impact

This vulnerability could lead to non-compliance with data protection regulations like GDPR or HIPAA by exposing sensitive personal or confidential data. Unauthorized access to private playlists may violate privacy requirements, leading to legal penalties, reputational damage, and loss of user trust.

Mitigation Strategies

Immediately update AVideo to the latest patched version if available. If no patch exists, restrict access to the video_from_program API endpoint via network-level controls or web application firewall rules. Review server logs for suspicious unauthenticated API queries to this endpoint.
