CWE-113
Summary
* A vulnerability in the Cisco Email Security Appliance (ESA) and Content
Security Management Appliance (SMA) software 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.
There are no workarounds that address this vulnerability.
