The version of IBM MQ Server running on the remote host is affected by a vulnerability. IBM MQ 7.5, 8.0, 9.0, 9.1, 9.2 LTS, and 9.2 CD could allow a remote attacker to execute arbitrary code on the system, caused by an unsafe deserialization of trusted data. An attacker could exploit this vulnerability to execute arbitrary code on the system.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
