Executive brief
The Awesome Support plugin for WordPress, which provides helpdesk and customer support functionality, contains a security flaw that allows users to view support tickets they do not own. By simply changing a ticket ID number, any logged-in user (such as a basic subscriber) can read sensitive information contained in other customers' support requests. This could lead to the exposure of private customer data, technical details, or internal communications stored within the helpdesk system.
Technical details
The vulnerability is classified as an Insecure Direct Object Reference (IDOR) within the wpas_get_ticket_replies_ajax() function of the Awesome Support plugin. The root cause is a failure to implement proper authorization checks to verify if the requesting user has the rights to view a specific ticket before returning its replies via AJAX. An attacker with at least subscriber-level authentication can exploit this by sending crafted requests with manipulated 'ticket_id' parameters. This allows for the unauthorized retrieval of sensitive data from all support tickets in the database. The issue is present in versions up to and including 6.3.7; users should update to the latest version where a patch has been applied.
