At a glance

CVE-2022-2926 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Download Manager WordPress plugin, affecting versions < 3.2.55. It carries a CVSS score of 4.9 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Admin level or above. The issue is fixed in version 3.2.55; sites on affected versions should update now. Disclosed September 2022, reported by Raad Haddad.

Vulnerability Overview

The Download Manager plugin for WordPress is vulnerable to Path Traversal in versions up to, and including, 3.2.54 via the File Browser Root field. This makes it possible for administrator-level attackers to list and read arbitrary files and folders outside of the blog directory.

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. A successful exploit has high impact on confidentiality.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Reaching this weakness in Download Manager < 3.2.55 takes an account at Admin level or above. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.

Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Download Manager the fix is 3.2.55: builds < 3.2.55 are affected, anything from 3.2.55 onward is not.

Remediation

Update to version 3.2.55, or a newer patched version

How does WordSec protect against this?

An attacker needs Admin access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Download Manager 3.2.55 closes this, and updating the plugin is the step that ends it.
