SANS Top-20 Entry: W2 Microsoft SQL Server (MSSQL) http://isc.sans.org/top20.html#w2 The Microsoft SQL Server (MSSQL) contains several serious vulnerabilities that allow remote attackers to obtain sensitive information, alter database content, compromise SQL servers, and, in some configurations, compromise server hosts. MSSQL vulnerabilities are well-publicized and actively under attack. Two recent MSSQL worms in May 2002 and January 2003 exploited several known MSSQL flaws. Hosts compromised by these worms generate a damaging level of network traffic when they scan for other vulnerable hosts.

Port 1433 is used by Microsoft SQL Server. SQLSnake is one worm taking advantage of SQL Server installs without password. As SQL Server is able to run batch files and command line programs, it can be used to download and install malware. Basic Protection: Use good passwords for all SQL Server accounts.
