IBM Director Systems, specifically CIM Server, contains a denial-of-service vulnerability that can allow a remote, unauthenticated attacker to render Director inoperative.
IBM Director is a suite of system management tools.
When a rogue connection request is made to IBM Director Systems, specifically the CIM Server, a thread is created that listens on a port, waiting for a specific response from the client. If the client does not send the expected response, the thread remains in memory listening, indicating a high CPU utilization until the client connects to it. If multiple rogue clients connect simultaneously, the finite number of connections can be exhausted causing server to crash.
IBM Director Systems will become inaccessible for management.
