Root command execution via crafted TCP requests

Published Jul 18, 2023 · Updated Oct 28, 2024

OS command injection in Kratos NGC Indoor Unit 9.1.0.4 allows remote attackers to execute Linux commands as root via crafted TCP requests. Kratos has not disclosed the listening service, request field, or unsafe command-construction operation that processes the crafted input. No authentication or user interaction is required; network reachability to the device is sufficient for full root-level command execution.
