Blue Coat ProxyClient < 3.3.3.3 / 3.4.x < 3.4.4.10 Certificate Validation MitM

high Nessus Plugin ID 93404

Language:

Synopsis

An application installed on the remote host is affected by a man-in-the-middle vulnerability.

Description

The version of Blue Coat ProxyClient installed on the remote Windows host is either prior to 3.3.3.3 or is 3.4.x prior to 3.4.4.10. It is, therefore, affected by a man-in-the-middle (MitM) vulnerability due to improper validation of the Client Manager certificate. A MitM attacker can exploit this, via a specially crafted certificate, to spoof ProxySG Client Managers, allowing the attacker to modify configurations and execute arbitrary software updates.

Solution

Upgrade to Blue Coat ProxyClient version 3.3.3.3 / 3.4.4.10 or later.
