CVE-2024-31806Public exploit

Unauthenticated reboot via RebootSystem request

Published Apr 8, 2024 · Updated Mar 13, 2025

Denial of service in TOTOLINK EX200 firmware 4.0.3c.7646_B20201211 allows remote attackers to reboot the device via an unauthenticated request. The RebootSystem function in system.so accepts a request without enforcing authorization and immediately restarts the range extender. Network access to the management interface is sufficient, and repeated requests can repeatedly interrupt wireless service.
