Super Admin escalation via unchecked AccessID

Published Feb 20, 2026 · Updated Feb 20, 2026

Privilege escalation in edu Business Solutions Print Shop Pro WebDesk 18.34 allows remote authenticated users to gain Super Admin access. The profile-update handler accepts the client-supplied AccessID field without server-side validation and writes the requested account role. Self-registration supplies the required account, after which changing AccessID from 5 to 1 exposes administrative functions and enables full application takeover.
