Cisco AnyConnect Secure Mobility Client 2.x < 3.1.13015.0 / 4.x < 4.2.1035.0 Arbitrary File Manipulation

medium Nessus Plugin ID 87894

Language:

Synopsis

The remote host is affected by an arbitrary file manipulation vulnerability.

Description

The Cisco AnyConnect Secure Mobility Client installed on the remote host is version 2.x or 3.x prior to 3.1.13015.0 or 4.x prior to 4.2.1035.0. It is, therefore, affected by an arbitrary file manipulation vulnerability due to missing source path validation in interprocess communication (IPC) commands. A local attacker can exploit this, via crafted IPC messages, to move arbitrary files with elevated privileges, resulting in a loss of integrity and a denial of service condition.

Solution

Upgrade to Cisco AnyConnect Secure Mobility Client version 3.1.13015.0 / 4.2.1035.0 or later.
