CVE-2021-32983Network attack vector

Unauthenticated code execution via unvalidated keyword parameter

Published Aug 30, 2021 · Updated Aug 3, 2024

Blind SQL injection in Delta Electronics DIAEnergie 1.7.5 and earlier allows remote attackers to execute code without authentication. The /DataHandler/Handler_CFG.ashx endpoint inserts the user-controlled keyword parameter into an SQL query without adequate validation. No credentials or user interaction are required, and successful exploitation runs arbitrary code as NT SERVICE\MSSQLSERVER.
