At a glance

CVE-2022-0828 is a high-severity Inadequate Encryption Strength vulnerability in the Download Manager WordPress plugin, affecting versions < 3.2.39. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 3.2.39; sites on affected versions should update now. Disclosed March 2022, reported by Diogo Real.

Vulnerability Overview

The Download Manager WordPress plugin before 3.2.39 uses the uniqid php function to generate the master key for a download, allowing an attacker to brute force the key with reasonable resources giving direct download access regardless of role based restrictions or password protections set for the download.

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. A successful exploit has high impact on confidentiality.

CWE-326: Inadequate Encryption Strength

The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.

Remediation

Update to version 3.2.39, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Download Manager 3.2.39 closes this, and updating the plugin is the step that ends it.
