The EAP-FAST authentication module in Cisco Secure Access Control Server (ACS) 4.x before 4.2.1.15.11, when a RADIUS server configuration is enabled, does not properly parse user identities, which allows remote attackers to execute arbitrary commands via crafted EAP-FAST packets, aka Bug ID CSCui57636.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
