Blue Coat Unified Agent < 4.1.3.151952 Certificate Validation MitM

high Nessus Plugin ID 93402

Language:

Synopsis

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

Description

The version of Blue Coat Unified Agent installed on the remote Windows host is prior to 4.1.3.151952. 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 Unified Agent version 4.1.3.151952 or later.
