Vulnerability Overview

The rtMedia for WordPress, BuddyPress and bbPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to 4.7.12. This is due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to perform an unauthorized action.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-639: Authorization Bypass Through User-Controlled Key

Reaching this weakness in rtMedia for WordPress, BuddyPress and bbPress < 4.7.12 takes an account at Subscriber level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For rtMedia for WordPress, BuddyPress and bbPress the fix is 4.7.12: builds < 4.7.12 are affected, anything from 4.7.12 onward is not.

Remediation

Update to version 4.7.12, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: rtMedia for WordPress, BuddyPress and bbPress 4.7.12 closes this, and updating the plugin is the step that ends it.
