Descriptions

An authentication bypass vulnerability in the Panorama context switching feature allows an attacker with network access to a Panorama's management interface to gain privileged access to managed firewalls. An attacker requires some knowledge of managed firewalls to exploit this issue. This issue does not affect Panorama configured with custom certificates authentication for communication between Panorama and managed devices. This issue affects: PAN-OS 7.1 versions earlier than 7.1.26; PAN-OS 8.1 versions earlier than 8.1.12; PAN-OS 9.0 versions earlier than 9.0.6; All versions of PAN-OS 8.0.

Una vulnerabilidad de omisión de autentificación en la función de conmutación de contexto de Panorama permite a un atacante con acceso de red a la interfaz de gestión de Panorama obtener un acceso privilegiado a la gestión del Firewall. Un atacante requiere cierto conocimiento de la gestión del Firewall para explotar esta cuestión. Este problema no afecta a Panorama configurado con certificados personalizados de autenticación para la comunicación entre Panorama y los dispositivos gestionados. Este problema afecta: PAN-OS versiones 7.1 anteriores a 7.1.26; PAN-OS versiones 8.0 anteriores a 8.0.21; PAN-OS versiones 8.1 anteriores a 8.1.12; PAN-OS versiones 9.0 anteriores a 9.0.6
