Security Bulletin
Summary
There is a potential HTTP response splitting vulnerability in IBM WebSphere Application Server as used by the IBM Virtualization Engine TS7700.
Vulnerability Details
CVEID: CVE-2016-0359
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.
CVSS Base Score: 6.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111929 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)
