Severity: High
Vulnerability Published: 2012-04-30
Patch Published: 2012-05-04
CVE [?]: CVE-2012-4598
CPE [?]: cpe:/a:mcafee:mcafee_virtual_technician

Synopsis

An ActiveX control installed on the remote Windows host can be abused to execute arbitrary code.

Description

The remote Windows host has a version of the McAfee Virtual Technician / ePolicy Orchestrator ActiveX control that allows execution of arbitrary code. The 'GetObject()' method can be used to load any class on the underlying operating system. For example, by loading the 'WScript.Shell' class, attackers can then run arbitrary operating system commands.

If an attacker can trick a user on the affected host into viewing a specially crafted HTML document, he can leverage this issue to execute arbitrary commands on the affected system subject to the user's privileges.

Solution

Upgrade to McAfee Virtual Technician 6.4 / ePolicy Orchestrator 1.0.8 or later.
