SMTP service in (1) Microsoft Windows 2000 and (2) Internet Mail Connector (IMC) in Exchange Server 5.5 does not properly handle responses to NTLM authentication, which allows remote attackers to perform mail relaying via an SMTP AUTH command using null session credentials.

Security readout for executives and security teams

This is an old Microsoft SMTP relay flaw. A remote party could abuse affected Windows 2000 SMTP or Exchange Server 5.5 IMC systems to send mail through them without valid credentials, creating spam, blacklist, and reputation risk. Exposure is most likely on legacy Windows 2000 SMTP services or Exchange Server 5.5 IMC systems that are still reachable over SMTP, especially internet-facing relay infrastructure or forgotten internal mail gateways. Treat this as a legacy exposure and reputation-risk item. Prioritize if any affected SMTP service is internet-facing or still trusted for outbound mail flow. Mitigation focus: Identify any remaining Windows 2000 SMTP or Exchange 5.5 IMC systems.; Review Microsoft MS02-011 for vendor-specified updates or mitigations.; Restrict SMTP relay access to trusted authenticated systems only..
