Palo Alto Networks PAN-OS 10.0.x < 10.0.1 Buffer Overflow

high Nessus Plugin ID 140528


The remote PAN-OS host is affected by a buffer overflow


The version of Palo Alto Networks PAN-OS running on the remote host is 10.0.x prior to 10.0.1. It is, therefore, affected by a buffer overflow vulnerability in the management web interface that allows authenticated administrators to disrupt system processes and potentially execute arbitrary code with root privileges.

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


Upgrade to PAN-OS 10.0.1 or later
