Quick assessment

Affected
Finsys dockhand
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.

在 1.0.50 之前的 Dockhand 版本中存在一个权限提升漏洞，允许来自其他租户的用户获得管理员权限，原因是未验证 OIDC 的 iss、aud、nonce 和 exp 声明。在共享提供程序（如 Microsoft Entra ID）中拥有其他租户管理员权限的攻击者可以重新创建映射的管理组，并以 Dockhand 管理员身份登录。
