CVE-2024-2421Network attack vector

Unauthenticated remote code execution via command injection

Published May 30, 2024 · Updated Aug 1, 2024

OS command injection in LenelS2 NetBox 5.6.1 and earlier allows remote attackers to execute commands with elevated permissions. Honeywell has not disclosed the affected endpoint, parameter, or command-construction path, only that special OS-command elements are not neutralized. No authentication or user interaction is required; successful exploitation can install programs, read or alter data, and interrupt the access-control service.
