Easy Social Icons < 3.2.0 – Admin+ Stored Cross-Site Scripting | Plugin Vulnerabilities

Description

The plugin does not sanitise and escape its saved settings before outputting them in attributes, which could allow high privilege users to perform Cross-Site Scripting attacks when the unfiltered_html capability is disallowed.

3.1.3 added some escaping, but data was output elsewhere

Proof of Concept

Put the following payload in any of the plugin's settings (there is client side validation, which can be bypassed by removing the type=number on input tags via the web browser inspector): "><script>alert(/XSS/)</script>

The XSS will be triggered in the settings, as well as Icons list
