10.0.x prior to 10.0.8 or 10.1.x prior to 10.1.2. It is, therefore, affected by a command injection vulnerability in 
its web interface component due to insufficient validation of user supplied input. An authenticated, remote attacker
can exploit this, by sending specially crafted requests, to execute arbitrary commands on an affected host.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
