Unparsed Raw Web Content Delivery

The product stores raw content or supporting code under the web document root with an extension that is not specifically handled by the server.


If code is stored in a file with an extension such as ".inc" or ".pl", and the web server does not have a handler for that extension, then the server will likely send the contents of the file directly to the requester without the pre-processing that was expected. When that file contains sensitive information such as database credentials, this may allow the attacker to compromise the application or associated components.


The following examples help to illustrate the nature of this weakness and describe methods or techniques which can be used to mitigate the risk.

Note that the examples here are by no means exhaustive and any given weakness may have many subtle varieties, each of which may require different detection methods or runtime controls.

Example One

The following code uses an include file to store database credentials:


$dbName = 'usersDB';
$dbPassword = 'skjdh#67nkjd3$3$';


$db = connectToDB($dbName, $dbPassword);
$db.authenticateUser($username, $password);

If the server does not have an explicit handler set for .inc files it may send the contents of database.inc to an attacker without pre-processing, if the attacker requests the file directly. This will expose the database name and password.
