PAN OS 11.1.6 AWS GWLB Bug

securehops — Mon, 07 Apr 2025 14:20:16 GMT

Hi All,

Just an informative post. There is an unreleased bug in PAN OS 11.1.6 which causes the source username to be displayed as junk values in the traffic logs, which has an impact on any firewall rules that rely on user/groups for authorization. It appears it only affects vm-series firewalls that are behind an AWS GWLB

TAC estimates the fix for this issue is targeted for release in the following PAN-OS versions: 11.2.6, 12.1.2, 11.1.9, and 12.2.0.

Bug ID: PAN-278322. Not sure why this isn't posted as known issues, if they already know when it will be addressed.
