9.7.x prior to 9.7.0.5, or 10.0.x prior to 10.0.0.2. It is, therefore, affected by a code injection vulnerability due to
a failure to properly handle input. A remote, authenticated actor can exploit this, by sending malicious traffic to
VMWare Cloud Director, in order to execute arbitrary code.

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