CVE-2022-24910Public exploitNetwork attack vector

Authenticated code execution via unbounded ping-result parsing

Published May 12, 2022 · Updated Apr 15, 2025

Buffer overflow in InHand Networks InRouter302 3.5.4 allows remote authenticated users to execute code through the ping-result API. parse_ping_result reads a line of up to 256 bytes from /tmp/ping_result.txt, then uses sscanf with unbounded %s conversions to fill three 32-byte buffers. The request must reach the port 4444 apply.cgi endpoint after a privileged user or a separate file-upload flaw controls the ping-results file, enabling code execution or a crash on the router.
