At a glance

CVE-2013-6797 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Blue Wrench Video Widget WordPress plugin, affecting versions <= 1.0.5. It carries a CVSS score of 7.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.0.0; sites on affected versions should update now. Disclosed October 2013, reported by Haider Mahmood.

Vulnerability Overview

Cross-site request forgery (CSRF) vulnerability in bluewrench-video-widget.php in the Blue Wrench Video Widget plugin before 2.0.0 for WordPress allows remote attackers to hijack the authentication of administrators for requests that embed arbitrary URLs via the bw_url parameter in the bw-videos page to wp-admin/admin.php, allowing the injection of arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Blue Wrench Video Widget <= 1.0.5 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Blue Wrench Video Widget the fix is 2.0.0: builds <= 1.0.5 are affected, anything from 2.0.0 onward is not.

Remediation

Update to version 2.0.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Blue Wrench Video Widget: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Blue Wrench Video Widget 2.0.0 closes this, and updating the plugin is the step that ends it.
