CVE-2002-0650: The keep-alive mechanism for Microsoft SQL Server 2000 allows remote attackers to cause a denial of service...

The keep-alive mechanism for Microsoft SQL Server 2000 allows remote attackers to cause a denial of service (bandwidth consumption) via a "ping" style packet to the Resolution Service (UDP port 1434) with a spoofed IP address of another SQL Server system, which causes the two servers to exchange packets in an infinite loop.

Security readout for executives and security teams

CVE-2002-0650 is a denial-of-service issue in Microsoft SQL Server 2000. An attacker could abuse the SQL Server Resolution Service on UDP 1434 so two servers repeatedly send traffic to each other, consuming bandwidth and disrupting service availability. Exposure is likely limited to environments still running Microsoft SQL Server 2000 with UDP 1434 reachable between SQL Server systems or from untrusted networks. The bundle does not identify other affected products or versions. Treat as a targeted availability risk for legacy SQL Server 2000 environments. It is not marked as actively exploited in the provided sources, but internet or broad internal exposure of UDP 1434 should be reduced promptly. Mitigation focus: Review Microsoft MS02-039 and apply vendor-directed remediation where applicable.; Inventory environments for Microsoft SQL Server 2000 instances.; Restrict UDP 1434 exposure to only required trusted networks..
