Title: Sitespring Server Denial of Service

BUG-ID: 2002028 Released: 01st Jul 2002


A malicious user with access to the Sitespring database engine port can crash both the runtime database engine and the Sitespring web service.


  • Sitespring 1.2.0(277.1) using Sybase runtime engine v7.0.2.1480


If the sybase database engine receives 1077 x chr(2) + \r\n\r\n it crashes. The web service will crash shortly after the database engine stops.

Vendor Response:

This was reported to the vendor on the 16th of April, 2002. There is currently no scheduled patch for this vulnerability. Vendor support for Sitespring is planned to end May, 2004.

Corrective action:

Apply IP filtering to the Sitespring server, so only the local host is allowed to connect to TCP port 2500.

On Win2000 or WinXP this can be done using the built-in IP filter functionality.
