According to its self-reported version, the IBM MQ server installed on the remote host is 8.0.0.x prior to 8.0.0.15 or 9.1.0.x prior to 9.1.0.6 LTS or 9.2 CD and is therefore affected by an information disclosure vulnerability. An authenticated, remote attacker can exploit this issue and cause a memory leak and crash the affected host.
