vulnerability in the support tunnel feature due to improper configuration of that feature. An authenticated, local
attacker can exploit this, by enabling the support tunnel, setting a key, and deriving the tunnel password, to allow the
attacker to run any system command with root access.
Note that Nessus has not attempted to exploit this issue but has instead relied only on the application's self-reported
