Technical details

A privilege escalation vulnerability exists in edu Business Solutions Print Shop Pro WebDesk v.18.34 due to improper privilege management (CWE-269) and a lack of server-side validation on the 'AccessID' parameter. An attacker can self-register an account and then submit a crafted profile update request to the '/PSP/app/web/reg/reg_process.asp' endpoint, setting the 'AccessID' parameter to '1'. Because the application trusts this client-supplied value without verifying the user's current authorization level, the attacker's account is promoted to Super Admin status. This allows for full application takeover and access to administrative functionality at '/PSP/appNet/ManagerHome.aspx'. The issue is resolved in version 19.76.
