"The version of Palo Alto Networks PAN-OS running on the remote host is 10.1.x prior to 10.1.12 or 10.2.x prior to 10.2.8

  - 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. (CVE-2024-3387)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
