Lotus Domino vulnerable to a denial of service via DOS device request

Vulnerability Note VU#890128

Original Release Date: 2001-07-12 | Last Revised: 2001-07-12

Overview

The Lotus Domino Web Server contains a flaw that could be exploited to cause a denial-of-service situation on the Windows and OS/2 Platforms.

Description

With the Lotus Domino Web Server, you can access DOS-devices. If this is done through the cgi-bin directory, a ncgihttp.exe process will be opened to handle the execution of the request. A flaw exists where this processing will not finish. After numerous requests have been made, the server will no longer respond to requests on tcp port 80.

Impact

A denial of service results on Windows and OS/2 platforms.

Solution

Upgrade to Notes/Domino 5.0.7 or later. See http://www.notes.net/qmrdown.nsf/QMRWelcome.

If possible, disable access to DOS-Devices through the web server's cgi-bin directory. An application layer filter may be able to detect and block such requests.
