CVE-2026-79901: Fortra BoKS boks_keytabmd predictable password generation

CVE-2026-79901 · Severity: critical · CVSS 9.9 · Published 2026-10-01

Fortra BoKS is a privileged account and credential management system that manages service account passwords in Active Directory. Affected versions generate passwords using a weak random seed based on the current Unix timestamp, allowing attackers who know the service principal name to predict and verify passwords offline, potentially gaining unauthorized access to critical service accounts.

Vendors: Fortra.

Technical details

The boks_keytabmd component generates Active Directory service-account passwords using a pseudo-random sequence seeded only with the current Unix timestamp. An attacker with knowledge of the service principal can estimate the password-change time and brute-force a limited candidate set of passwords, then verify them offline without requiring network access or authentication. This is a cryptographic weakness in password generation that affects the confidentiality of privileged credentials.
