CVE-2021-41295Network attack vector

Arbitrary system operations via forged web requests

Published Sep 30, 2021 · Updated Sep 17, 2024

Cross-site request forgery in ECOA BAS controllers allows remote attackers to perform arbitrary system operations through a user's browser. The web interface accepts forged GET, POST, PUT, and DELETE requests from a malicious page, but ECOA has not disclosed the affected endpoint or missing request-authenticity check. An authenticated browser session and user interaction are required; successful requests can create, read, modify, or delete controller data.
