Vulnerability Overview

The WordPress File Sharing Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to 2.0.5 (exclusive) via the upvf_pro_preview_file function due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to gain access to files and folders belonging to other users.

Technical Analysis

REMEDIATION: Update to version 2.0.5, or a newer patched version --- IDENTIFIER: CWE-639 (Authorization Bypass Through User-Controlled Key) The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
