CVE-2026-92583— AVideo through 29.0 Rate Limit Bypass via Non-Atomic Counter Increment

Quick assessment

Affected
WWBN AVideo
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

AVideo 版本 29.0 及之前的版本中， 函数存在竞争条件（race condition）。该函数未能原子化地递增速率限制计数器，使得攻击者可以通过发起并发请求来绕过所有速率限制，包括登录暴力破解保护机制。攻击者可以通过提交并行的凭据尝试，以任意倍数（仅取决于他们的连接并发度）超过文档中规定的“5 分钟内最多 30 次尝试”的登录限制。

Vulnerability Title
AVideo through 29.0 Rate Limit Bypass via Non-Atomic Counter Increment
Source: CVE Program / CVE List V5
Vulnerability Description
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.
