-- Vulnerability Details:
This vulnerability allows attackers to remotely obtain domain
credentials on vulnerable installations of Symantec Altiris Deployment 
Solution. User
interaction is not required to exploit this vulnerability.
Authentication is not required to exploit this vulnerability.

default on TCP port 402. The service allows a remote client to request
encrypted domain credentials without authentication. The encryption
lacks a salt allowing an attacker with a local installation of Altiris
Deployment Solution to easily decrypt the credentials.
