"The remote host is running iDRAC8 with a firmware version prior to 2.70.70.70 or iDRAC9 with a firmware version prior
to 3.36.36.36 and is therefore affected by an improper authorization vulnerability. A remote, authenticated iDRAC user
with low privileges can exploit this vulnerability to obtain sensitive information, such as password hashes.

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