Current Description

A vulnerability in the Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to conduct a HTTP response splitting attack. The vulnerability is due to the failure of the application or its environment to properly sanitize input values. An attacker could exploit this vulnerability by injecting malicious HTTP headers, controlling the response body, or splitting the response into multiple responses. An exploit could allow the attacker to perform cross-site scripting attacks, cross-user defacement, web cache poisoning, and similar exploits. Cisco Bug IDs: CSCvf16705.
