Summary
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.
