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.
