CVE-2022-26002Public exploitNetwork attack vector

Remote code execution via factory command overflow

Published May 12, 2022 · Updated Apr 15, 2025

Stack-based buffer overflow in InHand Networks InRouter302 3.5.4 allows remote authenticated users to execute code via the console. The hidden factory command parses oversized user data into a fixed-size stack buffer in the restricted SSH or Telnet console. The command requires the most-privileged router account; successful exploitation escapes the restricted console and gains code execution on the device.
