Title

Cisco ASA uRPF校验绕过漏洞

Description

Cisco Adaptive Security Appliance是一款自适应安全设备,可提供安全和VPN服务的模块。 Cisco Adaptive Security Appliance uRPF存在安全漏洞，由于未能正确校验外部接口IP报文的uRPF，如果IP地址存在路由表中并关联外部接口，该报文将不会正确被丢弃，远程攻击者可发送伪造的IP报文，绕过假药你，重定向报文到内部网络。

CVE-2015-4321 (GCVE-0-2015-4321)

Vulnerability from cvelistv5 – Published: 2015-08-20 10:00 – Updated: 2024-08-06 06:11

Summary

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.
