CVE-2022-27272Public exploitNetwork attack vector

Unauthenticated code execution via crafted packet

Published Apr 10, 2022 · Updated Aug 3, 2024

OS command injection in InHand Networks InRouter 900 firmware before 1.0.0.r11700 allows remote attackers to execute code via a crafted packet. The sub_1791C packet handler fails to neutralize command syntax in attacker-controlled packet data before invoking an OS command. The affected protocol and packet field are undisclosed; no authentication or user interaction is required, and injected commands run in the router's execution context.
