MQ administration manipulation via process-list argument injection

Argument injection in the websphere_mq agent plugin in Checkmk allows local users to alter a runmqsc invocation through crafted process command lines. The plugin parses ps output to choose a runmqsc argument without restricting attacker-controlled command-line text. Exploitation requires local low-privileged access and the deprecated plugin; the documented effect is manipulation of one MQ administration argument.
