IBM MQ 9.2 < 9.2.0.46 LTS (7294461)

high Nessus Plugin ID 379780

Synopsis

The remote web server is affected by a vulnerability.

Description

The version of IBM MQ Server running on the remote host is affected by a vulnerability as referenced in the 7294461 advisory.

- Apache CXF reads a top-level WSDL through its hardened StaxUtils path, which disables XML DTDs and external entities. However, any <wsdl:import> or <xsd:import> referenced from that top-level WSDL is handed off to WSDL4J, which does not disable DOCTYPE declarations or external entities. As a result, the protections applied to the top-level document do not extend to imported documents, leaving imported WSDL/XSD content vulnerable to XML External Entity (XXE) attacks. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue. (CVE-2026-65432)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to IBM MQ 9.2.0.46 LTS or later.
