CVE-2021-36206Network attack vector

Authentication bypass via crafted SQL queries

Published Oct 28, 2022 · Updated May 5, 2025

SQL query injection in Johnson Controls CEVAS before 1.01.46 allows remote attackers to bypass authentication and retrieve application data. The vendor identifies insufficient validation of user-controllable input before crafted SQL queries are processed but does not disclose the affected endpoint, parameter, or database call. No credentials or user interaction are required, and successful exploitation exposes stored data through the web-based billing and reporting service.
