WordPress Plugin Vulnerabilities
External Media < 1.0.36 - 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 Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
Proof of Concept
1. Open the settings page of the plugin. 2. On the setting page of this plugin, Select 'GoogleDrive' on the left side of the page. 3. Enter the following value on both the input box named 'Client ID' and the input box named 'Application ID'. The value is: 123';alert(/XSS/); '
