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

This script is Copyright (C) 2016 Tenable Network Security, Inc.


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.
