Summary
IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 is vulnerable to HTTP response splitting attacks. A remote attacker could exploit this vulnerability using specially-crafted URL to 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, cross-site scripting, and possibly obtain sensitive information. IBM X-Force ID: 129578.
