Cisco PIX是一款流行的硬件防火墙设备。 Cisco PIX 500系列安全设备处理SIP消息时存在问题，远程攻击者可以利用漏洞转发UDP包到任意设备，造成绕过防火墙设置获得敏感信息。 当接收到特殊的SIP消息时，PIX会打开UDP连接到内部网络的任意设备，此连接允许攻击者发送任意UDP通信到内部设备，导致绕过防火墙规则进行通信。 Cisco PIX Firewall 535 Cisco PIX Firewall 525 6.3 Cisco PIX Firewall 525 Cisco PIX Firewall 520 Cisco PIX Firewall 515E Cisco PIX Firewall 515 Cisco PIX Firewall 506 Cisco PIX Firewall 501 Cisco PIX Firewall 6.3.5 (112) Cisco PIX Firewall 6.3.3 (133) Cisco PIX Firewall 6.3.2 Cisco PIX Firewall 6.3.1 Cisco PIX Firewall 6.3 (5) Cisco PIX Firewall 6.3 (3.109) Cisco PIX Firewall 6.3 (3.102) Cisco PIX Firewall 6.3 (3) Cisco PIX Firewall 6.3 (1) Cisco PIX Firewall 6.3 Cisco PIX Firewall 6.2.3 (110) Cisco PIX Firewall 6.2.3 Cisco PIX Firewall 6.2.2 .111 Cisco PIX Firewall 6.2.2 Cisco PIX Firewall 6.2.1 Cisco PIX Firewall 6.2 (3.100) Cisco PIX Firewall 6.2 (3) Cisco PIX Firewall 6.2 (2) Cisco PIX Firewall 6.2 (1) Cisco PIX Firewall 6.2 Cisco PIX Firewall 6.1.5 (104) Cisco PIX Firewall 6.1.5 Cisco PIX Firewall 6.1.4 Cisco...
