Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Phpmyfaq/phpmyfaq, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary There is a Path Traversal vulnerability in Attachments that allows attackers with admin rights to upload malicious files to other locations of the web root. ### PoC 1. In settings, the attachment location is vulnerable to path traversal and can be set to e.g ..\hacked ![image](https://github.com/thorsten/phpMyFAQ/assets/63487456/6167ba74-254c-4aed-9c16-759e5ceafd81) 2. When the above is set, attachments files are now uploaded to e.g C:\Apps\XAMPP\htdocs\hacked instead of C:\Apps\XAMPP\htdocs\phpmyfaq\attachments 3. Verify this by uploading an attachment and see that the "hacked" directory is now created in the web root folder with the attachment file inside. ![image](https://github.com/thorsten/phpMyFAQ/assets/63487456/325df0cc-e9ee-48bd-a7bb-1295199b4d9e) ![image](https://github.com/thorsten/phpMyFAQ/assets/63487456/beb10a6a-9d56-4607-8da6-49581991b1fe) ### Impact Attackers can potentially upload malicious files outside the specified directory.
