Security Bulletin: HTTP response splitting attack affects IBM TS7700 Virtualization Engine (CVE-2015-2017)
There is a vulnerability in IBM WebSphere Application Server as used by the IBM TS7700 Virtualization Engine that could allow an HTTP response splitting attack.
DESCRIPTION: IBM WebSphere Application Server 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.
