CVE-2026-50751
Check Point Security Gateway contains an improper authentication vulnerability in IKEv1 key exchange that could allow an unauthenticated remote attacker to bypass user authentication and establish a remote access VPN connection without a valid user password.
Ver en NVDAnálisis
Esta vulnerabilidad crítica en Check Point Security Gateway permite a atacantes remotos no autenticados evadir la validación de certificados y conectarse a la VPN sin una contraseña válida. El fallo está siendo explotado activamente en el entorno real, comprometiendo directamente el acceso perimetral a la infraestructura interna de servidores y servicios. Se recomienda actualizar inmediatamente los gateways afectados que todavía utilicen el intercambio de llaves IKEv1.
