At a glance

CVE-2014-3923 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the DZS Video Gallery WordPress plugin, affecting versions < 7.95.

The issue is fixed in version 7.95; sites on affected versions should update now. Disclosed August 2014.

Vulnerability Overview

Multiple cross-site scripting (XSS) vulnerabilities in the Digital Zoom Studio (DZS) Video Gallery plugin for WordPress allow remote attackers to inject arbitrary web script or HTML via the logoLink parameter to (1) preview.swf, (2) preview_skin_rouge.swf, (3) preview_allchars.swf, or (4) preview_skin_overlay.swf in deploy/.

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.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in DZS Video Gallery < 7.95 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. 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. None of that substitutes for the fix: DZS Video Gallery 7.95 closes this, and updating the plugin is the step that ends it.
