CVE-2015-4550 is a vulnerability of currently unknown severity. The Cavium cryptographic-module firmware on Cisco Adaptive Security Appliance (ASA) devices with software 9.3(3) and 9.4(1.1) does not verify the AES-GCM Integrity Check Value (ICV) octets, which makes it easier for man-in-the-middle attackers to spoof IPSec and IKEv2 traffic by modifying packet data, aka Bug ID CSCuu66218.. EPSS estimates a 1.29% chance of exploitation in the next 30 days.
