3DescriptionCVE.org
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.
AnalysisAI
Rate-limit bypass in WWBN AVideo (all versions) allows unauthenticated remote attackers to perform unlimited credential-guessing against login endpoints by rotating arbitrary X-Real-IP or X-Forwarded-For header values per request. The enforceRateLimit() function uses the attacker-supplied header as the client identifier without verifying the request originates from a trusted proxy, nullifying IP-based throttling entirely. …

Vulnerability AssessmentAI
| Exploitation | No special conditions required beyond network access to the AVideo login endpoint. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 8.7 (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H) reflects trivially automated exploitation with no authentication or special prerequisites. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Consult the vendor security advisory at https://github.com/WWBN/AVideo/security/advisories/GHSA-gg65-574p-h4wc for the authoritative patch version and upgrade instructions; no exact fixed version number is independently confirmed from the available data, so patch availability per vendor advisory should be assumed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Implement Web Application Firewall (WAF) rules to block or validate X-Real-IP and X-Forwarded-For headers; configure your reverse proxy to strip these headers before they reach AVideo; and enable detailed login attempt logging with automated alerts on failed-login anomalies. …
