CVE-2022-25552Public exploitNetwork attack vector

Service interruption via unchecked SSID copy

Published Mar 9, 2022 · Updated Aug 3, 2024

Stack overflow in Tenda AX1806 firmware 1.0.0.1 allows remote attackers to interrupt service via a crafted ssid parameter. The /goform/fast_setting_wifi_set handler passes the HTTP ssid value through cmsUtl_strcpy to strcpy and copies it into a stack buffer without checking its length. An unauthenticated network request is sufficient, and the disclosed consequence is limited to service interruption; code execution has not been demonstrated.
