CyberRota Analysis
AI-GeneratedThe vulnerability affects WWBN AVideo versions e01e41ecc and earlier, allowing unauthenticated attackers to bypass brute-force rate limiting on the login endpoint and 13 other endpoints. By exploiting the flawed rate limiting mechanism that misidentifies clients without a User-Agent header as bots, attackers can perform unlimited login attempts, significantly increasing the risk of successful password-guessing attacks. Organizations using affected versions of AVideo should prioritize patching this vulnerability to protect against potential unauthorized access.

Original NVD Description
WWBN AVideo (current e01e41ecc and earlier) contains a brute-force rate limiting bypass in enforceRateLimit(), which protects login.json.php and 13 other endpoints. The function stores its attempt counter via a cache layer (ObjectYPT::setCacheGlobal) that silently discards writes for any client identified as a bot by isBot(). Because isBot() treats a missing User-Agent header as a bot by default — and also matches common bot identifiers such as 'curl', 'bot', 'crawler', and 'spider' — the counter never increments for such clients, so the rate limit never fires. An unauthenticated attacker can therefore submit unlimited login attempts (e.g., by omitting the User-Agent header or using curl's default User-Agent), enabling unrestricted password-guessing attacks.
