Vulnerability Overview

The Shared Files – Advanced File Sharing & Download Manager with Frontend Uploads plugin for WordPress is vulnerable to Stored Cross-Site Scripting via uploaded file content in all versions up to, and including, 1.7.5 due to the plugin not returning the correct 'Content-Type' header when viewing uploaded files. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in uploaded files that will execute whenever a user accesses the injected upload.

Technical Analysis

REMEDIATION: Update to version 1.7.6, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
