WordPress Plugin Vulnerabilities
Image Hover Effects Css3 <= 4.5 - Admin+ Stored XSS
Description
The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
Proof of Concept
1. Go to Hover Effects » Hover Effects » Add New Hover Effect. 2. Enter the payload: <img src onerror=alert(/TESTXSS/)>, then copy the shortcode and create a new page with the shortcode. 3. Go to the page where you saved the shortcode, XSS popup.
