At a glance

CVE-2022-3124 is a medium-severity Missing Authorization vulnerability in the Frontend File Manager Plugin WordPress plugin, affecting versions <= 21.2. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 21.3; sites on affected versions should update now. Disclosed September 2022, reported by Raad Haddad.

Vulnerability Overview

The Frontend File Manager plugin for WordPress is vulnerable to authorization bypass due to a missing capability check and lacking authentication in versions up to, and including, 21.2. This makes it possible for unauthenticated attackers to rename uploaded files on the site.

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

Reaching this weakness in Frontend File Manager Plugin <= 21.2 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 Frontend File Manager Plugin the fix is 21.3: builds <= 21.2 are affected, anything from 21.3 onward is not.

Remediation

Update to version 21.3, 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: Frontend File Manager Plugin 21.3 closes this, and updating the plugin is the step that ends it.
