Oracle 9iAS allows access to CGI script source code within CGI-BIN directory

Vulnerability Note VU#936507

Original Release Date: 2002-02-27 | Last Revised: 2002-03-05


Oracle 9i Application Server (9iAS) allows remote anonymous users to view source code in CGI scripts stored in the Apache cgi-bin. Attackers may analyze these scripts to discover usernames, passwords, or other proprietary data or methods.


The default Apache configuration file in Oracle 9iAS provides a Location alias from "/perl" to "/cgi-bin". Because this alias is not defined as a ScriptAlias, documents accessed through the "/perl" alias are not interpreted as scripts should be. Instead, the server simply outputs the contents of the document.


Attackers may read the source code of CGI scripts by requesting them through the "/perl" alias. Attackers may analyze source code to discover usernames, passwords, or other proprietary data or methods.


The CERT/CC is currently unaware of a practical solution to this problem.

Edit the "httpd.conf" file to change the "/perl" alias into a ScriptAlias.
