An attacker\\n          can leverage this flaw to target an Active Directory Domain Controller and make repeated authentication attempts\\n          using NULL data fields which will succeed every 1 in 256 tries (~0.4%). This module leverages the vulnerability\\n          to reset the machine account password to an empty string, which will then allow the attacker to authenticate as\\n          the machine account. After exploitation, it's important to restore this password to it's original value.
