Description

This module exploits a command execution vulnerability in Samba
versions 3.0.20 through 3.0.25rc3 when using the non-default
"username map script" configuration option. By specifying a username
containing shell meta characters, attackers can execute arbitrary
commands.

No authentication is needed to exploit this vulnerability since
this option is used to map usernames prior to authentication!
