The Cisco AnyConnect Secure Mobility Client installed on the remote host is a version prior to 3.1.10010.0, or is version 4.0.x prior to 4.0.4014.0, or version 4.1.x prior to 4.1.4011.0. It is, therefore, affected by a flaw that allows unauthenticated IPC commands to install software as root. A local attacker, by sending a specially crafted IPC command, can exploit this to execute arbitrary programs with elevated privileges.
