CVE-2002-1256: The SMB signing capability in the Server Message Block (SMB) protocol in Microsoft Windows 2000 and Windows...

The SMB signing capability in the Server Message Block (SMB) protocol in Microsoft Windows 2000 and Windows XP allows attackers to disable the digital signing settings in an SMB session to force the data to be sent unsigned, then inject data into the session without detection, e.g. by modifying group policy information sent from a domain controller.

Security readout for executives and security teams

This is a legacy Microsoft Windows SMB signing weakness. On Windows 2000 and Windows XP, an attacker positioned to interfere with SMB traffic could force a session to stop using signing, making trusted file and policy traffic easier to alter without detection. Exposure is likely limited to environments still running or emulating Windows 2000 or Windows XP SMB services, especially domain-connected systems using SMB-based policy delivery. Modern supported Windows versions are not identified as affected in the provided bundle. Treat this as high priority only if legacy Windows 2000 or XP systems remain in production or support critical domain workflows. If none exist, document non-exposure and monitor asset inventory for exceptions. Mitigation focus: Identify and retire Windows 2000 and Windows XP systems where possible.; Review and apply Microsoft MS02-070 vendor guidance for any remaining affected systems.; Segment legacy SMB systems away from domain controllers and sensitive management networks..
