WordPress Plugin Vulnerabilities
Responsive Lightbox2 < 1.0.4 - Contributor+ Stored XSS
Description
The plugin does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks
Proof of Concept
As a contributor, put, the following shortcode in a page/post [lightbox2 url='" onmouseover=javascript:alert(/XSS/) "'] The XSS will be triggered when viewing/previewing the page/post and moving the mouse over the "Click Here" text in the post
Affects Plugins
Fixed in version 1.0.4
