Vulnerability from variot
A vulnerability in the Decryption Policy Default Action functionality of the Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to bypass a configured drop policy and allow traffic onto the network that should have been denied. The vulnerability is due to the incorrect handling of SSL-encrypted traffic when Decrypt for End-User Notification is disabled in the configuration. An attacker could exploit this vulnerability by sending a SSL connection through the affected device. A successful exploit could allow the attacker to bypass a configured drop policy to block specific SSL connections. Releases 10.1.x and 10.5.x are affected. Cisco Web Security Appliance (WSA) Contains a resource exhaustion vulnerability.Information may be tampered with. CiscoWebSecurityAppliance is a WEB secure access device. 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 CSCvm91630. The appliance provides SaaS-based access control, real-time network reporting and tracking, and security policy formulation. The vulnerability stems from the fact that the program does not properly handle traffic encrypted by SSL
