CVE-2024-46045Public exploit

Authenticated router crash via oversized page parameter

Published Sep 13, 2024 · Updated Oct 15, 2024

Stack overflow in CH22 Firmware 1.0.0.6(468) allows remote authenticated users on the adjacent network to crash the router. The frmL7PlotForm handler passes the POST page parameter to sprintf when building an im.asp URL without limiting the write to the destination array. Access to the adjacent management network and a low-privilege session are required; an oversized value can interrupt router service.
