medium Nessus Plugin ID 59193
New! Plugin Severity Now Using CVSS v3

Synopsis

An update management application installed on the remote Windows host has a privilege escalation vulnerability.

Description

The version of Symantec LiveUpdate Administrator (LUA) installed on the remote host has a privilege escalation vulnerability. The installation directory allows write access to the Everyone group. This directory contains batch files that are periodically executed as SYSTEM. A local, unprivileged attacker could exploit this by creating or modifying files that will be executed as SYSTEM, resulting in privilege escalation.

A partial fix for this issue was included in LUA 2.3.1, but it does not mitigate all possible attack vectors.

Solution

Upgrade to Symantec LiveUpdate Administrator 2.3.2 or later.
