Last modified
CVE-2015-4321 is a vulnerability of currently unknown severity. The Unicast Reverse Path Forwarding (uRPF) implementation in Cisco Adaptive Security Appliance (ASA) Software 9.3(1.50), 9.3(2.100), 9.3(3), and 9.4(1) mishandles cases where an IP address belongs to an internal interface but is also in the ASA routing table, which allows remote attackers to bypass uRPF validation via spoofed packets, aka Bug ID CSCuv60724.. EPSS estimates a 1.73% chance of exploitation in the next 30 days.
