CVE-2022-26042Public exploitNetwork attack vector

Authenticated command execution via daretools system call

Published May 12, 2022 · Updated Apr 15, 2025

OS command injection in InHand Networks InRouter302 3.5.4 allows remote authenticated users to execute arbitrary commands through the router console. The hidden inhand command starts /sbin/daretools after a hard-coded password check, and daretools passes lines beginning with a or r directly to system(). Low-privileged Telnet or SSH console access and the embedded password are required; successful exploitation opens an underlying BusyBox shell.
