    Internet Security Systems Security Brief
    January 25, 2003

    Microsoft SQL Slammer Worm Propagation


    ISS X-Force has learned of a worm that is spreading via Microsoft SQL
    servers. The worm is responsible for large amounts of Internet traffic as
    well as millions of UDP/IP probes at the time of this alert's publication.
    This worm attempts to exploit MS/SQL servers vulnerable to the SQL Server
    Resolution service buffer overflow (CVE CAN-2002-0649). Once a vulnerable
    computer is compromised, the worm will infect that target, randomly select a
    new target, and resend the exploit and propagation code to that host.


    Although the Slammer worm is not destructive to the infected host, it does
    generate a damaging level of network traffic when it scans for additional
    targets. A large amount of network traffic is created by the worm, which
    scans random IP addresses for vulnerable servers.
