IBM Control Center 6.2.1 through 6.3.1 is vulnerable to an external service interaction attack, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability to induce the application to perform server-side DNS lookups or HTTP requests to arbitrary domain names. By submitting suitable payloads, an attacker can cause the application server to attack other systems that it can interact with.
An interaction error occurs when two entities have correct behavior when running independently of each other, but when they are integrated as components in a larger system or process, they introduce incorrect behaviors that may cause resultant weaknesses.
