Palo Alto Networks PAN-OS 11.1.x < 11.1.10 / 11.2.x < 11.2.8 Vulnerability

medium Nessus Plugin ID 249234

Synopsis

The remote PAN-OS host is affected by a vulnerability

Description

The version of Palo Alto Networks PAN-OS running on the remote host is 11.1.x prior to 11.1.10 or 11.2.x prior to 11.2.8. It is, therefore, affected by a vulnerability.

 A problem with the implementation of the MACsec protocol in Palo Alto Networks PAN-OS results in the cleartext exposure of the connectivity association key (CAK). This issue is only applicable to PA-7500 Series devices which are in an NGFW cluster.
 A user who possesses this key can read messages being sent between devices in a NGFW Cluster. There is no impact in non-clustered firewalls or clusters of firewalls that do not enable MACsec.




Tenable has extracted the preceding description block directly from the PAN-OS security advisory.

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

Solution

Upgrade to PAN-OS 11.1.10 / 11.2.8 or later
