Administrator access via arbitrary credential acceptance

Published Jun 13, 2026 · Updated Jun 13, 2026

Authentication bypass in BUK TS-G Gas Station Automation System 2.9.1 through 2.10.2 allows remote attackers to gain administrator access. The /php/ajax-login.php endpoint returns userid=1 for arbitrary credentials, while privileged endpoints do not validate a server-side session. Network access to the web interface is sufficient to read or modify configuration for fuel equipment, payment devices, users, and pricing.
