high Nessus Plugin ID 152164
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 printer driver installed on the remote host is vulnerable to a privilege escalation.


The printer driver installed on the remote host is missing a security update. It is, therefore, affected by a privilege escalation vulnerability. An authenticated, local attacker can exploit this to gain privileged or administrator access to the system.


HP has released a set of patches. See vendor advisory.
