CVE-2022-37070Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized param

Published Aug 25, 2022 · Updated Aug 3, 2024

OS command injection in H3C GR-1200W firmware MiniGRW1A0V100R006 and earlier allows remote attackers to execute commands via param. DelL2tpLNSList formats attacker-controlled param data into a command string with snprintf and invokes system without neutralizing shell substitution. No authenticated session or user interaction is required, and successful injection runs commands with the web service process's privileges.
