WordPress Plugin Vulnerabilities
Ultimate Product Catalog < 5.2.6 - 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. Navigate to the plugin setup page. 2. Go to the "Categories" section. 3. In the "Category Name" field, input the payload: `<noscript><p title="</noscript><img src=x onerror=alert(1)>` 4. Go to the fourth page and select "Create a Product". 5. In every field except "Product Image", input the payload: `<noscript><p title="</noscript><img src=x onerror=alert(1)>` 6. The payload will be executed, demonstrating the vulnerability.
