Description
A weak (low bit strength) device certificate in Palo Alto Networks Panorama
software enables an attacker to perform a meddler-in-the-middle (MitM) attack
to capture encrypted traffic between the Panorama management server and the
firewalls it manages. With sufficient computing resources, the attacker could
break encrypted communication and expose sensitive information that is shared
between the management server and the firewalls.
