Ipswitch WhatsUp Gold is a Microsoft Windows based network monitoring
application. More information is available at
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:
Program: C:Program FilesWhatsUpwhatsupg.exe
abnormal program termination
Successful exploitation allows unauthenticated remote attackers to crash
the WhatsUp Gold application, thereby preventing legitimate usage. The
WhatsUp Gold web server is not enabled by default.
iDEFENSE has confirmed the existence of this vulnerability against
WhatsUp Gold versions 8.03 and the latest version 8.03 Hotfix 1. It is
suspected that earlier versions are also vulnerable.
Disable the WhatsUp Gold web server if it is not required.
