CVE-2026-79901: Fortra Boks Manager Boks-Server

Critical severity, CVSS 9.9. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Fortra Boks Manager Boks-Server: before 9.0.0.6 (fixed in 9.0.0.6)
