Vulnerability from variot
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. Vendors have confirmed this vulnerability Bug ID CSCuv60724 It is released as.Via a forged packet by a third party, uRPF May be bypassed. Cisco Adaptive Security Appliance Software is prone to a remote security-bypass vulnerability. An attacker can exploit this issue to bypass security restrictions and perform unauthorized actions. This may aid in further attacks. This issue is tracked by Cisco Bug ID CSCuv60724. The appliance also includes IPS (Intrusion Prevention System), SSL VPN, IPSec VPN, anti-spam, and more. The vulnerability comes from the fact that the program does not perform uRPF authentication correctly. The following releases are affected: Cisco ASA Release 9.3(1.50), Release 9.3(2.100), Release 9.3(3), Release 9.4(1)
