Remotely reachable, low-complexity, unauthenticated race on a default endpoint (AV:N/AC:L/PR:N/UI:N); impact limited to weakening a control (C:L/I:L), no availability effect, no scope change.

AVideo through 29.0 contains a race condition in the enforceRateLimit() function that fails to atomically increment rate limit counters, allowing attackers to bypass all rate limits including login brute-force protection by issuing concurrent requests. Attackers can submit parallel credential attempts to exceed the documented 30-attempts-per-5-minutes login limit by an arbitrary factor determined only by their connection concurrency.
AnalysisAI
Non-atomic rate-limit counter increments in AVideo through 29.0 let remote unauthenticated attackers bypass the platform's documented 30-attempts-per-5-minute login throttle simply by firing genuinely concurrent credential guesses, multiplying their effective attempt rate by their connection concurrency. The weakness only degrades a protective control, so abuse still requires a brute-forceable account (weak or guessable password, no MFA, and no independent account lockout), which keeps this a moderate, defense-in-depth issue rather than a critical priority. …

Vulnerability AssessmentAI
| Exploitation | No special product configuration is required - the race exists in the default enforceRateLimit() logic and is reachable by remote unauthenticated attackers against any AVideo instance through version 29.0. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a moderate, defense-in-depth weakness rather than a critical priority. … 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 | Follow the vendor advisory GHSA-8jrm-qg5f-966w and upgrade AVideo to the latest release beyond 29.0; no specific patched version number is confirmed in the supplied data, so verify the fixed release on the advisory before deploying, and confirm that the fix makes the counter increment atomic rather than merely widening the window. … Detailed patch versions, workarounds, and compensating controls in full report. |
