CVE-2020-12734Public exploit

Device lockout via unauthenticated Wi-Fi reconfiguration

Published Jul 15, 2021 · Updated Aug 4, 2024

Missing authorization in DEPSTECH WiFi Digital Microscope 3 allows remote attackers to change its SSID and password over Wi-Fi. The wireless configuration interface accepts unauthenticated credential changes; the published research does not identify the responsible endpoint or function. An attacker must be within wireless range; changed credentials lock out the owner, and the device provides no factory-reset recovery path.
