Unparsed Raw Web Content Delivery
Weakness ID: 433 (Weakness Variant)Status: Incomplete
+ Description

Description Summary

The software stores raw content or supporting code under the web document root with an extension that is not specifically handled by the server, resulting in an information leak.

Extended Description

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 will result in an information leak that allows the attacker to compromise the application or associated components.

+ Potential Mitigations

Clean up debug code before deploying the application.

Perform a type check before interpreting files.

Do not store sentitive information in files which may be misinterpreted, causing a possible information leak.
