The Cisco AnyConnect Secure Mobility Client installed on the remote Mac OS X host is a version prior to 3.1.10010.0, or is version 4.0.x prior to 4.0.4013.0, or version 4.1.x prior to 4.1.4011.0. It is, therefore, affected by a flaw that allows unauthenticated IPC commands to write files. A local, authenticated attacker, using a specially crafted IPC command, can write or overwrite arbitrary files.
