The klif.sys driver in Kaspersky Labs Anti-Virus 5.0.227, 5.0.228, and 5.0.335 on Windows 2000 allows local users to gain privileges by modifying certain critical code addresses that are later accessed by privileged programs.

Security readout for executives and security teams

This is a legacy local privilege-escalation issue in Kaspersky Anti-Virus on Windows 2000. A user who already has local access could potentially gain higher privileges through the klif.sys driver. The business risk is mainly for old, unmanaged, or forgotten Windows 2000 systems still running the affected product versions. Exposure is likely limited to legacy Windows 2000 hosts running Kaspersky Anti-Virus 5.0.227, 5.0.228, or 5.0.335. Modern Windows systems or newer Kaspersky versions are not identified as affected in the supplied sources. Treat this as a legacy hygiene and privilege-escalation risk, not a broad internet-facing emergency. Priority should rise if Windows 2000 systems remain in production, especially where multiple users or third parties can log in locally. Mitigation focus: Identify and retire affected Kaspersky Anti-Virus 5.0 installations on Windows 2000.; Check Kaspersky guidance for any historical vendor fix or supported upgrade path.; Replace unsupported Windows 2000 systems where business operations still depend on them..
