CVE-2002-1256 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 5.38% chance of exploitation in the next 30 days.
