At a glance

CVE-2014-1906 is a high-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Broadcast Live Video WordPress plugin, affecting versions < 4.29.5. 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 4.29.5; sites on affected versions should update now. Disclosed February 2014, reported by High-Tech Bridge Security Research Lab.

Vulnerability Overview

Multiple cross-site scripting (XSS) vulnerabilities in the VideoWhisper Live Streaming Integration plugin before 4.29.5 for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) m parameter to lb_status.php; (2) msg parameter to vc_chatlog.php; n parameter to (3) channel.php, (4) htmlchat.php, (5) video.php, or (6) videotext.php; (7) message parameter to lb_logout.php; or ct parameter to (8) lb_status.php or (9) v_status.php in ls/.

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 Broadcast Live Video < 4.29.5 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 Broadcast Live Video the fix is 4.29.5: builds < 4.29.5 are affected, anything from 4.29.5 onward is not.

Remediation

Update to version 4.29.5, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Broadcast Live Video: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Broadcast Live Video 4.29.5 closes this, and updating the plugin is the step that ends it.
