Note rule content has been altered for this rule. Don't know if we should say so in documentation. Rule: -- Sid: 1022 -- Summary: This event is generated when an attempt is made to execute a shell command possibly associated with an exploit with the Microsoft Jet database engine. -- Impact: Remote access.

Exploit code is freely available. -- False Positives: None Known. -- False Negatives: None Known. -- Corrective Action: Disable Jet ODBC drivers if they are not required. Upgrade to Jet 4.0. -- Contributors: Original rule writer unknown Modified by Brian Caswell <bmc@sourcefire.com> Sourcefire Research Team Judy Novak <judy.novak@sourcefire.com> -- Additional References: Microsoft http://www.microsoft.com/technet/security/bulletin/ms99-030.asp Bugtraq: http://www.securityfocus.com/bid/286 --
