Insecure deserialization in IBM App Connect Enterprise Toolkit allows local users to execute arbitrary code with user interaction. IBM has not identified the deserialization locus, serialized data format, or operation that accepts the untrusted input. Exploitation requires local access and user interaction and executes attacker-controlled code in the affected user's context.
