WordPress Plugin Vulnerabilities
Nextgen Gallery < 3.59.1 - 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 Cross-Site Scripting attacks even when unfiltered_html is disallowed
Proof of Concept
1. Add the "NextGEN Media RSS" Widget to the blog (Appearance > Widgets) 2. Change the "Tooltip text for Media RSS link" to `feed" asdasd='' onmouseover='alert(1)'` 3. Save the settings and view the site 4. Move your mouse over the icon/text to see the XSS
