Kerentanan Cleartext Transmission of Sensitive Information pada netun helpflash iot firmware. Skor CVSS 3.1 6.6 (Medium) menurut CISA ADP.

Deskripsi (NVD)

The OTA firmware update mechanism in Netun Solutions HelpFlash IoT (firmware v18_178_221102_ASCII_PRO_1R5_50) uses hard-coded WiFi credentials identical across all devices and does not authenticate update servers or validate firmware signatures. An attacker with brief physical access can activate OTA mode (8-second button press), create a malicious WiFi AP using the known credentials, and serve malicious firmware via unauthenticated HTTP to achieve arbitrary code execution on this safety-critical emergency signaling device.
