CWE-433: 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.
How it's found
Unparsed Raw Web Content Delivery is a specific, narrowly defined instance of a broader pattern. Testers confirm it with targeted code review and a proof-of-concept input that exercises the exact code path this weakness describes.
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.
