Vulnerability Overview

The ConvertBox Auto Embed WordPress plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘cboxarea’ shortcode in versions up to, and including, 1.0.19 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

REMEDIATION: Update to version 1.0.20, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
