WordPress Plugin Vulnerabilities
Shared Files < 1.6.61 - Admin+ Stored Cross-Site Scripting
Description
The plugin does not sanitise and escape the Download Counter Text settings, which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed
Proof of Concept
Put the following payload in the Download Counter Text settings (and tick the Show Download Counter as well): <svg/onload=alert(/XSS/)> The XSS will be triggered in pages/posts where the [shared_files] is embed and has at least one file
Affects Plugins
Fixed in version 1.6.72
