high Nessus Plugin ID 96314
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 NULL pointer dereference flaw in the web management interface, specifically in the parseRange() function within file rx.c, when handling HTTP requests involving a Range header with an empty value.
An unauthenticated, remote attacker can exploit this, via a specially crafted request, to cause the Appweb process for the management interface to terminate, resulting in a denial of service condition.

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 5.0.20 / 5.1.13 / 6.0.15 / 6.1.15 / 7.0.11 / 7.1.6 or later.
