Vulnerability Overview

The Disqus Conditional Load plugin for WordPress is vulnerable to Stored Cross-Site Scripting via plugin options such as 'dcl_div_width', 'dcl_type', and others in versions up to, and including, 11.1.0 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 affects multi-site installations and installations where unfiltered_html has been disabled.

Technical Analysis

REMEDIATION: Update to version 11.1.2, 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.
