A format string vulnerability in the Varrcvr daemon of PAN-OS on PA-7000 Series devices with a Log Forwarding Card (LFC) allows remote attackers to crash the daemon creating a denial of service condition or potentially execute code with root privileges. This issue affects Palo Alto Networks PAN-OS 9.0 versions before 9.0.7; PAN-OS 9.1 versions before 9.1.2 on PA-7000 Series devices with an LFC installed and configured. This issue requires WildFire services to be configured and enabled. This issue does not affect PAN-OS 8.1 and earlier releases. This issue does not affect any other PA Series firewalls.

The version of Palo Alto Networks PAN-OS running on the remote host is 9.0.x prior to 9.0.7 or 9.1.x prior to 9.1.2.
It is, therefore, affected by a remote code execution vulnerability. Improper restriction of communications to Log Forwarding Card (LFC) on PA-7000 Series devices with the WildFire service enabled may allow an unauthenticated attacker with network access to the LFC to gain root access to PAN-OS.

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