WordPress Plugin Vulnerabilities
Shared Files < 1.7.6 - Unauthenticated Stored Cross-Site Scripting
Description
The plugin does not return the right Content-Type header for the specified uploaded file. Therefore, an attacker can upload an allowed file extension injected with malicious scripts.
Proof of Concept
Upload an allowed WordPress extension such as JPG and inject it with a script such as: <script>alert(1);</script>. To access the resource, the uploaded file ID can be seen in the source code of the (Preview) button under data-file-url as such: /shared-files/{FILE_ID}/?xss.jpg and can be triggered using HTTP://url.com/shared-files/{FILE_ID}/?xss.jpg
