COMMAND Veritas BackupExec 9.0 is vulnerable to Slammer worm SYSTEMS AFFECTED Veritas BackupExec 9.0 PROBLEM Marcus Beaman [marcus(dot)beaman(at)state(dot)or(dot)us] found following: Veritas BackupExec 9.0 that recently shipped out on CD to registered owners is vulnerable to the SQL Slammer worm. http://seer.support.veritas.com/docs/254244.htm For some reason, Veritas shipped the CDs with an old, unpatched version of MS SQL Desktop Engine that is vulnerable. It took the worm less than two hours to find the box I upgraded to BackupExec 9.0 on this morning and have it spewing 20mb/sec onto the network (impressive for an old dual PPro 200). If you know of anyone else running BackupExec on their servers, you may want to warn them before they try to upgrade to the new version. BackupExec 8.x is apparently not vulnerable unless it's also running the Network Storage Executive. SOLUTION firewall the MSQL port, or ask veritas for a patch
