Unspecified vulnerability in the queue manager in IBM WebSphere MQ (WMQ) 5.3, 6.0 before 6.0.2.6, and 7.0 before 7.0.0.2 allows local users to gain privileges via vectors related to the (1) setmqaut, (2) dmpmqaut, and (3) dspmqaut authorization commands.
The WebSphere MQ XA 5.3 before FP13 and 6.0.x before 6.0.2.1 client for Windows, when running in an MTS or a COM+ environment, grants the PROCESSDUPHANDLE privilege to the Everyone group upon connection to a queue manager, which allows local users to duplicate an arbitrary handle and possibly hijack an arbitrary process.
