CVE-2021-27715Network attack vector

Root command execution via unauthenticated API requests

Published Sep 8, 2023 · Updated Jul 9, 2026

Command injection in MoFi Network MOFI4500-4GXeLTE V2 3.5.6-xnet-5052 allows remote attackers to execute commands as root via HTTP. The router's HTTP API accepts crafted requests without enforcing authentication and passes injected commands for execution with root privileges. No credentials or user interaction are required, and API access also exposes configuration, kernel logs, GPS coordinates, and WAN passwords.
