It is possible to read the sensitive configuration files from an Oracle 9i Application Server without any authorization. This can lead to an intruder gaining access to sensitive information about the server and potentially compromising it.
Default installation of the Oracle 9i Application Server does not set appropriate permissions to configuration files that contain sensitive information (see VU#476619). Since these files are not protected by default, any user can access the files directly through a virtual directory and view the contents. When these files have the appropriate permissions set, an HTTP request to access the files results in a "403 Forbidden" response. However, access can be gained by requesting the file using the XSQLServlet. This servlet will bypass any permissions placed on the file and display its content.
An intruder can read files that shouldn't be accessable, and gain sensitive information about the configuration of the server. This information can be used to compromise the server.
The CERT/CC is currently unaware of a practical solution to this problem.
Apply the appropriate permissions to the configuration files and remove the XSQLServlet, if possible.
