Affects Microsoft Commerce Server 2000

Vulnerability is a buffer overrun in the authentication process used by
Commerce Server (via the AuthFilt ISAPI.dll). As such, it can be
exploited to allow arbitrary code to execute on the Commerce Server in
the LocalSystem context (e.g. root access).

Authfilt is not used by any other process than Commerce Server, even
though it is used on IIS when Commerce Server is installed (iows, this
isn't an IIS issue, its an issue with the ISAPI filter used only by
Commerce Server).

Microsoft rates this issue as Critical for Internet/Intranet services,
doesn't apply to clients.

Cheers,
