Cisco AnyConnect Secure Mobility Client 3.1.x < 4.3.4019.0 / 4.4.x < 4.4.225.0 Privilege Escalation

high Nessus Plugin ID 95951

Language:

Synopsis

A VPN application installed on the remote host is affected by a privilege escalation vulnerability.

Description

The version of Cisco AnyConnect Secure Mobility Client installed on the remote Windows host is 3.x or 4.x prior to 4.3.4019.0 or 4.4.x prior to 4.4.225.0. It is, therefore, affected by a privilege escalation vulnerability due to incorrect permissions of a system directory at installation time. A local attacker can exploit this, by creating a specially crafted interprocess communication (IPC) to the virtual private network (VPN) agent process, to execute commands on the host with elevated system level privileges.

Solution

Upgrade to Cisco AnyConnect Secure Mobility Client version 4.3.4019.0 / 4.4.225.0 or later.
