IBM Rational Quality Manager 5.0 through 5.0.2 and 6.0 through 6.0.5 are 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: 142658.
