Vulnerability Overview

The DZS Video Gallery plugin for WordPress is vulnerable to remote/local file inclusion in versions up to, and excluding, 7.95. This can allow unauthenticated attackers to retrieve local and remote files with a .swf extension.

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-98: Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')

Reaching this weakness in DZS Video Gallery < 7.95 takes a caller who can reach the endpoint. PHP file inclusion means a path used by include or require is built from request data, so the file that gets executed is under the caller's influence.

Including an attacker-influenced file executes its contents, which is why this class is routinely chained with an upload or log-poisoning step to reach code execution. For DZS Video Gallery the fix is 7.95: builds < 7.95 are affected, anything from 7.95 onward is not.

Remediation

Update to version 7.95, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to DZS Video Gallery: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: DZS Video Gallery 7.95 closes this, and updating the plugin is the step that ends it.
