Synopsis :

It is possible to obtain the physical path of the remote server
web root.

Description :

Oracle 9iAS allows remote attackers to obtain the physical path of a file
under the server root via a request for a non-existent .JSP file. The default
error generated leaks the pathname in an error message.

Solution : 

Ensure that virtual paths of URL is different from the actual directory 
path. Also, do not use the <servletzonepath> directory in 
'ApJServMount <servletzonepath> <servletzone>' to store data or files. 

Upgrading to Oracle 9iAS 1.1.2.0.0 will also fix this issue.
