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.

ZoneMinder 是一款免费的开源闭路电视（CCTV）软件应用。在版本 1.34.0 至 1.36.38 中，Web 界面在 中对失败的令牌（token）认证处理不当。 函数在令牌格式错误或签名无效时返回 ，但其调用者将该返回值赋给了全局变量 。由于 通过 来检测用户是否已登录，布尔值 被误判为用户已存在，从而跳过了正常的登录重定向流程。 该缺陷可导致触发依赖外层认证机制的视图，包括“区域（zones）”视图。该视图接受攻击者指定的监控摄像头（monitor）ID，并在缺乏独立权限检查的情况下披露监控摄像头和区

Vulnerability Title
ZoneMinder failed token handling bypasses web authentication
Source: CVE Program / CVE List V5
Vulnerability Description
ZoneMinder is a free, open source closed-circuit television software application. In versions 1.34.0 through 1.36.38, the web interface mishandles failed token authentication in web/includes/auth.php. validateToken() returns false when a token is malformed or has an invalid signature, but the caller assigns that value to the global $user variable; because web/index.php tests isset($user), boolean false is treated as a present user and the normal login redirect is skipped. This can dispatch views that rely on the outer authentication gate, including the zones view, which accepts an attacker-selected monitor ID and discloses monitor and zone metadata without an independent permission check. Permission helpers receive the false user value and deny privileged operations, so unauthorized state changes have not been established. This vulnerability is fixed in version 1.36.63, where conversion to ZM\User objects causes invalid token state to fail before view dispatch. Later defense-in-depth changes explicitly leave $user unset after failed token validation and reject non-ZM\User values at the web authentication gate.
