WordPress Plugin Vulnerabilities
WP Contact Slider < 2.4.7 - Editor+ Stored Cross-Site Scripting
Description
The plugin does not sanitize and escape the Text to Display settings of sliders, which could allow high privileged users such as editor and above to perform Cross-Site Scripting attacks even when the unfiltered_html is disallowed
Proof of Concept
Create/edit a Slider, select the "text or HTML" for the " What would you like to display?" setting (at the bottom of the page), and put the following payload in the "Text to display" field while in Text mode: <img src onerror=alert(/XSS/)> The XSS will be triggered in the post/page where the slider is embed/displayed
Affects Plugins
Fixed in version 2.4.7
