The Dragon-Fire IDS remote web interface under version 1.0 has an insecure CGI script which allows for users to remotely execute commands as the user nobody. This could lead to a remote compromise of the system running Dragon-Fire.

|echo 'uname -a'

The output of the command will then be displayed in the right hand window of the IDS WWW interface.
