The DNS implementation in smtpsvc.dll before 6.0.2600.5949 in Microsoft Windows 2000 SP4 and earlier, Windows XP SP3 and earlier, Windows Server 2003 SP2 and earlier, Windows Server 2008 SP2 and earlier, Windows Server 2008 R2, Exchange Server 2003 SP3 and earlier, Exchange Server 2007 SP2 and earlier, and Exchange Server 2010 uses predictable transaction IDs that are formed by incrementing a previous ID by 1, which makes it easier for man-in-the-middle attackers to spoof DNS responses, a different vulnerability than CVE-2010-0024 and CVE-2010-0025.

Security readout for executives and security teams

This flaw affects legacy Microsoft SMTP/DNS handling. It makes DNS query identifiers predictable, which can help a man-in-the-middle attacker spoof DNS responses and misdirect mail-related lookups. The bundle does not show active exploitation or a CVSS score. Exposure is most likely on legacy Windows and Exchange systems listed in the CVE: Windows 2000, XP, Server 2003, Server 2008, Server 2008 R2, Exchange 2003, Exchange 2007, and Exchange 2010 running affected smtpsvc.dll builds. Treat this as a legacy infrastructure risk, not a broad modern emergency. Prioritize if old Microsoft SMTP or Exchange systems still route business mail, especially across untrusted networks. Mitigation focus: Inventory systems using Microsoft SMTP Service or affected Exchange versions.; Check Microsoft/vendor guidance for the applicable security update or supported replacement path.; Verify smtpsvc.dll version where applicable; the CVE references builds before 6.0.2600.5949..
