CVE-2022-4980Known exploitationNetwork attack vector

Unauthenticated administrator creation via first-installation workflow

Published Sep 19, 2025 · Updated Nov 21, 2025

Authentication bypass in General Bytes Crypto Application Server allows remote attackers to create administrators through the admin interface. The default-installation page accepts an unauthenticated URL call and repeats its first-administrator creation operation after setup. Internet-exposed admin services on ports 7777 or 443 are reachable without credentials, and the resulting account can redirect ATM funds.
