At a glance

This record tracks a medium-severity Missing Authorization vulnerability in the Download Manager WordPress plugin, affecting versions < 3.1.18. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 3.1.18; sites on affected versions should update now. Disclosed April 2021.

Vulnerability Overview

The WordPress Download Manager plugin for WordPress is vulnerable to unauthorized download duplication in versions up to, and including, 3.1.17. This is due to missing authorization and nonce validation on the duplicate() function. This makes it possible for unauthenticated attackers to duplicate any of a vulnerable sites downloads.

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 privileges on the target site, and no interaction from a victim user.

CWE-862: Missing Authorization

Download Manager < 3.1.18 carries this weakness at duplicate(), and reaching it takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Download Manager the fix is 3.1.18: builds < 3.1.18 are affected, anything from 3.1.18 onward is not.

Remediation

Update to version 3.1.18, 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: Download Manager 3.1.18 closes this, and updating the plugin is the step that ends it.
