Description
IBM Cloud Orchestrator 2.4 through 2.4.0.5 and 2.5 through 2.5.0.9 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. IBM X-Force ID: 162236.
