CVE-2020-36126Public exploitNetwork attack vector

Authenticated privilege escalation via broken access control

Published May 7, 2021 · Updated Aug 4, 2024

Incorrect access control in Pax Technology PAXSTORE 7.0.8_20200511171508 and earlier allows remote authenticated users to alter other users' data. Marketplace endpoints accept reads and writes for records owned by other users, applications, and payment terminals, allowing token impersonation. Authentication is required, and the resulting access can disclose, modify, or destroy information without affecting service availability.
