CVE-2022-1357Network attack vector

Unauthenticated code execution via logger command injection

Published May 17, 2022 · Updated Apr 16, 2025

OS command injection in Cambium Networks cnMaestro On-Premises allows remote attackers to execute code with web-server privileges. The server fails to validate attacker-controlled data before appending it to the logger command, causing injected content to be executed. No authentication or user interaction is required, and successful exploitation grants control at the web server's privilege level.
