WORDPRESS, XSS

CVE-2024-0612 — Content Views WP Plugin <= 3.6.2 Administrator+ Stored Cross-Site Scritpting

The Content Views – Post Grid, Slider, Accordion (Gutenberg Blocks and Shortcode) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.6.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions 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.

Proof of Concepts

  1. Add new view then go to Display Setting
  2. Input XSS Payload in “Read More” section Read More<body onload=confirm(document.domain)>
  3. Create post then add shortcode of that created View

XSS Payload will triggered on created Post

Impact

This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
