description=[[
Performs brute force password auditing against a Nexpose vulnerability scanner
using the API 1.1.
As the Nexpose application enforces account lockout after 4 incorrect login
attempts, the script performs only 3 guesses per default. This can be
altered by supplying the <code>brute.guesses</code> argument a different
value or 0 (zero) to guess the whole dictionary.
