CVE-2022-26420Public exploitNetwork attack vector

Root command execution via unsanitized interface name

Published May 12, 2022 · Updated Apr 15, 2025

OS command injection in InHand Networks InRouter302 3.5.37 allows remote authenticated users to execute commands as root over Telnet or SSH. The console port functionality interpolates an unsanitized interface-name argument into an ip link set shell command and passes it to system(). Access requires valid router-console credentials plus the infactory password; successful injection opens a root shell with control of the appliance.
