Strategic Overview

Vulnerability Overview

The Chat Button plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin settings in versions up to, and including, 1.8.9.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only impacts multi-site installations and installations where unfiltered_html has been disabled.

Technical Analysis

REMEDIATION: Update to version 1.8.10, 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.
