Executive Summary

This is a Server-Side Request Forgery (SSRF) vulnerability in WWBN AVideo. The _json_decode function fetches remote URLs and local file paths without proper validation. Unauthenticated attackers can send POST requests with file paths or HTTP URLs to login.json.php, causing the application to read local files or access internal services. The fetched content is then parsed as login credentials.

Detection Guidance

To detect this vulnerability, monitor network traffic for POST requests to login.json.php with file paths or HTTP URLs in the body. Check server logs for suspicious file reads or internal service access attempts. Use tools like curl to test if the server responds to crafted POST requests with local file paths or internal URLs.

Impact Analysis

An attacker could read sensitive local files, access internal services, or gain unauthorized access by manipulating login credentials. This could lead to data breaches, system compromise, or further network infiltration depending on the exposed services.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Non-compliance may result in legal penalties, fines, or reputational damage.

Mitigation Strategies

Immediately update WWBN AVideo to the latest commit (c3edcc274c389816d434acadac07ee78eaf330c1) or later. If no patch is available, disable or restrict access to login.json.php. Implement network-level controls to block unauthorized POST requests to sensitive endpoints. Review and restrict file system permissions to prevent unauthorized file reads.
