CVE-2025-4692Network attack vector

Privilege escalation via crafted JWT submission

Published May 22, 2025 · Updated May 23, 2025

Incorrect privilege assignment in ABUP IoT Cloud Platform allows remote authenticated users to access unauthorized device profiles via a crafted JWT. The platform accepts a maliciously crafted JWT at an exposed cloud method and assigns privileges that the authenticated account should not receive. Exploitation requires a legitimate low-privilege account and passive user interaction; successful attacks expose profiles for any managed device.
