CVE-2025-12278Network attack vector

Post-logout authenticated session retention

Published Oct 26, 2025 · Updated Oct 26, 2025

Insufficient session expiration in Azure Access Technology BLU-IC2 and BLU-IC4 through 1.19.5 allows remote attackers to retain access after logout. The vendor has not published which logout handler or session-state operation fails to invalidate the authenticated session. Exploitation requires possession of a valid session before logout, and retained access remains bounded by that session's existing controller permissions.
