Title: Sage Software MAS 200 Denial of Service Vulnerability

Severity: HIGH

Description:

MAS 200 is a client/server accounting platform which runs on 32-bit Windows platforms.

A user is able to connect to port 10000 on a server running MAS 200. Once connected, the user can enter the <control> x key combination ten times to disable the server side application. At this point the client application is no longer able to connect to the server.

The next time a user connects to port 10000 on the host server, a message is displayed stating that the host has been disabled.

To resume service, the administrator must restart MAS 200 manually.

It has been reported that other key combinations such as <control> q and the arrow keys, will produce the same results.

Affected Products:

  • Sage Software MAS 200
