Unrestricted Upload of File with Dangerous Type
CWE-434
The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
We track 2,513 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 8.9. 28 have been exploited in real attacks.
How this weakness is prevented
- Architecture and Design: Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.
- Architecture and Design: When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
- Architecture and Design: Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically.
- Architecture and Design: Define a very limited set of allowable extensions and only generate filenames that end in these extensions. Consider the possibility of XSS (CWE-79) before allowing.html or.htm file types.
- Implementation: Ensure that only one extension is used in the filename. Some web servers, including some versions of Apache, may process files based on inner extensions so that filename.php.gif is fed to the PHP interpreter.
