Title: Microsoft Windows 2000 SMTP Improper Authentication Vulnerability
Severity: HIGH
Description:
The SMTP (Simple Mail Transfer Protocol) server is an internet service which implements mail transfer according to the SMTP protocol. SMTP installs by default in Windows 2000.
Due to a flaw in the authentication process of the SMTP service in Windows 2000, it is possible for an unauthorized host to successfully authenticate and use the SMTP service.
This behaviour occurs when invalid credentials are submitted to the service during the authentication process. The precise technical details are not currently known, however the result is that a user without valid credentials can be successfully authenticated.
This vulnerability could enable an unauthorized user to abuse SMTP services (mass e-mailing, forging, etc.).
The vendor has reported that this vulnerability only affects the SMTP service and will not enable an attacker to execute operating system commands or gain administrative access on the host.
It should be noted that only stand-alone machines are affected by this issue and not domain members.
Unfortunately, no further technical details have been provided. Updates will be published as more information becomes available.
