WordPress Advanced Ticket System < 1.0.64 - Authenticated Stored Cross-Site Scripting (XSS)

less than 1 minute read

Description

The plugin does not sanitize or escape form values before saving to the database or when outputting, which allows high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.

Proof of Concept

Navigate to Tickets > Add New > add all information on the title, post, Ticket type, Ticket priority, Ticket status > click update and intercept the request using burp suite. The parameters "wats_select_ticket_type", "wats_select_ticket_priority", "wats_select_ticket_status" can be injected with cross-site scripting (XSS), such as test"><script>alert('test')</script>; test"><script>alert(document.cookie)</script> payload. Next Click Forward on burp suite. To trigger the XSS payload, Open the permalink post/ticket page.
