Vulnerability Overview

The Insert or Embed Articulate Content into WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via e-Learning widget file upload in all versions up to, and including, 4.3000000023 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject 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 interaction from a victim user.

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

Reaching this weakness in Insert or Embed Articulate Content into WordPress <= 4.3000000023 takes an account at Author level or above. 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 Insert or Embed Articulate Content into WordPress the fix is 4.3000000025: builds <= 4.3000000023 are affected, anything from 4.3000000025 onward is not.

Remediation

Update to version 4.3000000025, or a newer patched version

How does WordSec protect against this?

An attacker needs Author access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Insert or Embed Articulate Content into WordPress 4.3000000025 closes this, and updating the plugin is the step that ends it.
