CVE-2002-0650 is a medium vulnerability (CVSS 5.0) in Microsoft Sql Server, published August 12, 2002. No source lists public exploit code. EPSS puts the chance of exploitation in the next 30 days at 18.3%, the 97th percentile. No source names a fixed version.
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.
