Background
The Jenkins VMware Lab Manager Slaves Plugin is a Maven package (org.jenkins-ci.plugins:labmanager) that provides integration between Jenkins and VMware Lab Manager. It allows users to manage and provision virtual machines for testing and development purposes. The plugin is responsible for creating and managing slave nodes in the Lab Manager environment. However, versions 0.2.8 and earlier of the plugin suffer from a vulnerability that results in the storage of passwords in plain text format in the global config.xml file on the Jenkins controller. This file can be accessed by users with file system access to the Jenkins controller.
