The Cisco AnyConnect Secure Mobility Client installed on the remote Mac OS X host is version 3.x prior to 3.1.10010.0 or 4.x prior to 4.1.4011.0. It is, therefore, affected by a flaw due to improper sanitization of user-supplied input. An unauthenticated, remote attacker can exploit this issue, by convincing a user to connect to a malicious head-end system, to traverse outside a restricted path and thus write or overwrite arbitrary files in the active user’s context.
