Cisco Adaptive Security Appliances (ASA) 5500 series devices with software 7.2 through 8.4 do not properly perform proxy authentication during attempts to cut through a firewall, which allows remote attackers to obtain sensitive information via a connection attempt, aka Bug ID CSCtx42746.
Weakness
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
