Description

WWBN AVideo fails to validate trusted proxies before accepting X-Real-IP and X-Forwarded-For headers, allowing attackers to spoof the client address used by enforceRateLimit(). Attackers can rotate the header value per request to bypass login rate limiting and perform unlimited credential guessing attacks.
