CVE-2023-2567Network attack vector

Authenticated SQL injection via improperly validated Query parameters

Published Sep 19, 2023 · Updated Feb 27, 2025

SQL injection in Nozomi Networks Guardian and CMC before 22.6.3 or 23.0.0 through 23.0.x allows remote authenticated users to run SQL. The Query functionality passes improperly validated parameters into DBMS statements, causing attacker-controlled SQL to be executed. A valid web management account and network access are required; exploitation permits uncontrolled database reads, arbitrary changes, or service interruption.
