AIX 6.1 / 7.1.2 / 7.1.3 : IBM PowerHA SystemMirror CSPOC Privilege Escalation

critical Nessus Plugin ID 94674
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.

Synopsis

The remote AIX host is missing a security patch.

Description

The remote AIX host is running a version of IBM PowerHA SystemMirror that is missing a security patch. It is, therefore, affected by a privilege escalation vulnerability in the Cluster Single Point of Control (CSPOC) feature that occurs when adding an authenticated, remote user to the list that allows cluster-wide changing of the password. An authenticated, remote attacker who has been added to this list can exploit this issue, via a vulnerable script shipped with the product, to gain root privileges by using a 'su root' action.

Solution

Install the appropriate interim fix according to the vendor advisory.
