BACKGROUND

Ipswitch WhatsUp Gold is a Microsoft Windows based network monitoring

DESCRIPTION

Remote exploitation of a denial of service vulnerability in Ipswitch
Inc.'s WhatsUp Gold allows attackers to cause the application to crash.

The problem specifically exists in the handling of reserved DOS device
names. By generating a GET request for 'prn.htm' to the HTTP daemon
installed by WhatsUp Gold, the application crashes and the following
Runtime Library error is displayed:

the WhatsUp Gold application, thereby preventing legitimate usage. The
