CVE-2002-0624
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedBuffer overflow in the password encryption function of Microsoft SQL Server 2000, including Microsoft SQL Server Desktop Engine (MSDE) 2000, allows remote attackers to gain control of the database and execute arbitrary code via SQL Server Authentication, aka "Unchecked Buffer in Password Encryption Procedure."
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceBuffer overflow vulnerability in the password encryption function of Microsoft SQL Server 2000 and MSDE 2000 allows remote attackers to execute arbitrary code via SQL Server Authentication, potentially gaining full control of the database.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify SQL Server versionOpen SQL Server Enterprise Manager or query SELECT @@VERSION to determine the exact build number. Check if it shows SQL Server 2000 or MSDE 2000 without Service Pack 3 or later applied.Affected if The installed version is SQL Server 2000 or MSDE 2000 and the build is below version 8.00.760 (SP3)
-
Verify SQL Server Authentication modeIn Enterprise Manager, right-click the server, select Properties, and check the Security tab. Alternatively, run: SELECT serverproperty('IsIntegratedSecurityOnly'). A value of 0 means SQL Server Authentication is enabled.Affected if SQL Server Authentication mode is enabled (IsIntegratedSecurityOnly returns 0)
-
Confirm network exposureCheck if the server is listening on TCP port 1433. Use netstat -an | findstr 1433 or check SQL Server Network Utility (svrnetcn.exe) for enabled protocols.Affected if TCP/IP protocol is enabled and port 1433 is open to network access
You are affected if SQL Server 2000 or MSDE 2000 without SP3 is installed, SQL Server Authentication mode is enabled, and the database is network accessible on port 1433.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the Microsoft patch (SQL Server 2000 SP3 or later), or migrate to a supported SQL Server version; alternatively, use Windows Authentication mode instead of SQL Server Authentication and restrict network access to port 1433.
