CVE-2026-79901— Predictable Active Directory service-account passwords in BoKS Manager
Quick assessment
Affected
Fortra BoKS Manager boks-server
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.
在使用 BoKS keytab 管理的部署环境中，受影响的 boks_keytabmd 版本会基于当前 Unix 时间戳作为种子，从一个可预测的伪随机序列中生成 Active Directory 服务账户密码。如果攻击者知晓服务主体名称（service principal），并能估算出密码更改的时间，则可以重现一个有限的候选密码集合，并在离线环境中对这些候选项进行验证。

Vulnerability Title
Predictable Active Directory service-account passwords in BoKS Manager
Source: CVE Program / CVE List V5
Vulnerability Description
In deployments using BoKS keytab management, affected versions of boks_keytabmd generate Active Directory service-account passwords from a predictable pseudo-random sequence seeded with the current Unix timestamp. An attacker who knows the service principal and can estimate the password-change time can reproduce a limited candidate set and verify candidates offline.
