Vulnerability Overview

The Comments – wpDiscuz plugin for WordPress is vulnerable to insecure direct object reference in versions up to, and including, 7.4.2. This is due to insufficient validation on the 'wmu_attachments' user-controlled key. This makes it possible for authenticated attackers with subscriber-level capabilities and above to inject attachments that do not belong to them into post comments.

Technical Analysis

REMEDIATION: Update to version 7.5, 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.
