CVE-2025-49602: Keyfactor EJBCA authentication cache persistence after admin removal

CVE-2025-49602 · Severity: info · Published 2026-10-30

EJBCA is a certificate authority and public key infrastructure management system used by enterprises to issue and manage digital certificates. When an administrator's access is revoked while they maintain an active session, the system may continue to cache their authentication credentials beyond the intended timeout period, allowing the former administrator to retain unauthorized access to sensitive PKI functions.

Vendors: Keyfactor.

Technical details

A caching mechanism in EJBCA 9 fails to invalidate authentication sessions immediately when an administrator is removed from their role. An attacker with a valid TLS session can exploit this race condition to perform administrative actions after losing role privileges, as the authentication cache persists longer than the configured maximum time (default 30 seconds). This affects session-level privilege revocation and requires the attacker to already hold a valid authenticated session at the time of role removal.
