CVE-2026-50099

Naxclow IoT Platform Insertion of sensitive information into Externally-Accessible file or directory

Published Jun 12, 2026 CVSS 4.0 · 5.1 Medium EPSS < 1% KEV · Not listed
Description
During WiFi association, Naxclow device firmware prints the host network’s SSID, PSK, and negotiated WPA keys in cleartext to an exposed UART console on production hardware. The UART pads are labeled, run with default serial settings, and drop to an interactive RT-Thread shell that permits arbitrary memory reads, enabling full firmware extraction. An attacker with brief physical access, common for outdoor-mounted devices, can therefore recover WiFi credentials and bootstrap firmware-side attacks.
