Event History
Frequently Asked Questions
Who can exploit this issue?
An attacker needs an authenticated WordPress account with subscriber-level access or higher. The vulnerable AJAX action is reachable over the network and does not require user interaction.
What access or data does an attacker need to target another user's order?
The attacker must be able to submit a crafted request to the marketking_send_refund AJAX action and supply an order ID. The flaw allows arbitrary order IDs to be used for refund requests, including orders the attacker did not place.
Which versions should be remediated?
MarketKing versions before 2.1.72 are affected. Update to version 2.1.72 or later.
How can an administrator look for attempted exploitation?
Review refund-request activity for requests associated with accounts that did not place the targeted orders. Also investigate AJAX requests invoking marketking_send_refund where the requesting user and supplied order ID do not correspond.
