Awesome Support < 6.3.8 - Authenticated (Subscriber+) Insecure Direct Object Reference to Unauthorized Ticket Reply Access via 'ticket_id' Parameter

Description

The Awesome Support – WordPress HelpDesk & Support Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 6.3.7. This is due to the wpas_get_ticket_replies_ajax() function failing to verify whether the authenticated user has permission to view the specific ticket being requested. This makes it possible for authenticated attackers, with subscriber-level access and above, to access sensitive information from all support tickets in the system by manipulating the ticket_id parameter.
