CVEID: CVE-2016-6816
DESCRIPTION: Apache Tomcat is vulnerable to HTTP response splitting attacks,
caused by improper validation of user-supplied input. A remote attacker
could exploit this vulnerability to inject arbitrary HTTP headers and cause
the server to return a split response, once the URL is clicked. This would
allow the attacker to perform further attacks, such as Web cache poisoning
or cross-site scripting, and possibly obtain sensitive information.
