medium Nessus Plugin ID 91958
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote host is affected by a denial of service vulnerability.


The Palo Alto Networks PAN-OS running on the remote host is affected by a denial of service vulnerability in the API hosted on the management interface, specifically in the panUserLogin() function within, due to improper validation of user-supplied input to the 'username' and 'password' parameters. An unauthenticated, remote attacker can exploit this, via a crafted request, to cause the process to terminate.

Note that PAN-OS is reportedly affected by other vulnerabilities as well; however, Nessus has not tested for these.


Upgrade to Palo Alto Networks PAN-OS version 7.0.8 or later.
