According to its self-reported version, the IBM MQ server installed on the remote host is 8.0.0.x prior to 8.0.0.14 or 9.1.0.x prior to 9.1.0.4 LTS or 9.1.4 CD and is therefore affected by a security restrictions bypass vulnerabylity. An authenticated, remote attacker can exploit this issue, via an unspecified vector, to gain privileged rights in the affected host.
