CVE-2022-37822Public exploit

Stack overflow via route static handler

Published Aug 25, 2022 · Updated Aug 3, 2024

A stack overflow in Tenda AX1803 v1.0.0.1 allows local users to corrupt memory through the fromSetRouteStatic function. The route-static handler performs an unsafe stack operation on attacker-controlled input, overwriting stack memory. Local low-privilege access is required, and public records do not specify whether corruption results in a crash or code execution.
