At a glance

CVE-2022-2633 is a high-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the All-in-One Video Gallery WordPress plugin, affecting versions 2.5.8 – 2.6.0. 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 2.6.1; sites on affected versions should update now. Disclosed August 2022, reported by Gabriele Zuddas.

Vulnerability Overview

The All-in-One Video Gallery plugin for WordPress is vulnerable to arbitrary file downloads and blind server-side request forgery via the 'dl' parameter found in the ~/public/video.php file in versions up to, and including 2.6.0. This makes it possible for unauthenticated users to download sensitive files hosted on the affected server and forge requests to the server.

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

Reaching this weakness in All-in-One Video Gallery 2.5.8 – 2.6.0 takes a caller who can reach the endpoint. 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 All-in-One Video Gallery the fix is 2.6.1: builds 2.5.8 – 2.6.0 are affected, anything from 2.6.1 onward is not.

Remediation

Update to version 2.6.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to All-in-One Video Gallery: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: All-in-One Video Gallery 2.6.1 closes this, and updating the plugin is the step that ends it.
