WordPress Plugin Vulnerabilities
Site Reviews < 6.7.1 - 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 Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
Proof of Concept
1. Login as Admin. 2. Go to http://vulnerable-site.tld/wp-admin/edit.php?post_type=site-review&page=glsr-settings&tab=general 3. Make some changes in the `schema` tab and intercept the request. 4. The form will have the parameter `site_reviews_v6[settings][general][notification_message]` 5. Insert the following payload in it ``` <strong>A new {review_rating}-star review has been submitted:</strong> </textarea><script>alert(1)</script> {review_title} {review_content} {review_author} <{review_email}> - {review_ip} {review_link} ``` 6. Hit send and the xss payload will be saved and will be triggered whenever the settings page is open.
