CVE-2023-3066Public exploitNetwork attack vector

Account impersonation via unbound request identifier

Published Jun 5, 2023 · Updated Jan 8, 2025

Incorrect authorization in Mobatime AMXGT-100 1.3.20 and earlier allows remote authenticated users to impersonate other users. The API trusts the user identifier repeated in each JSON request and fails to bind it to the authenticated session, so replacing that value selects another account. Low-privileged access is sufficient, and choosing an administrator identifier exposes that account's data and administrative functions.
