Vulnerable Application:  
Sun Microsystems NetBeans (recently renamed to Forte') Java IDE  
  
Versions tested:  
Netbeans Developer 3.0 Beta  
Forte Community Edition 1.0 Beta  
unknown if earlier versions have vulnerability  
  
Platform tested:  
Windows NT 4.0  
unknown if other platforms have vulnerability  
  
Description:  
The IDE includes an internal HTTP server to try Java code. The settings  
indicate that access must be explicitly granted on a per IP address bases.  
However, when service is enabled for one machine, the HTTP server allows  
remote access to root and all subdirectories from any machine. NOTE, for  
the NetBeans 3.0 Beta version, this is the default activity. Therefore, no  
action is required by the user for the vulnerability to exist. Under the  
Forte' 1.0 Beta version, a user must enable at least one address in the  
HTTP server settings for the vulnerability to exist. However, once a  
single IP address is entered, any machine can connect to the internal HTTP  
server port (default is 8082). Even if all IP addresses are removed, the  
server continues to allow connections when the IDE is running.  
  
Example:  
While the IDE is running connecting with any browser to  
http://vvv.xxx.yyy.zzz:8082/..  
provides a listing of the root directory.  
Sub-directories can then be accessed.  
  
Solution (work around):  
1) Set the HTTP Server "Enable" setting to False in Project settings.  
or  
2) Remove the HTTP Server module in Global settings.  
  
Vendor notified: Yes.
