Vulnerability from fkie_nvd - Published: 2021-09-30 11:15 - Updated: 2026-06-17 04:08
Severity
Summary
ECOA BAS controller is vulnerable to insecure direct object references that occur when the application provides direct access to objects based on user-supplied input. As a result of this vulnerability, attackers with general user's privilege can remotely bypass authorization and access the hidden resources in the system and execute privileged functionalities.
