Summary
On Yealink UVC40 E2 devices before 319.410.0.71, an attacker with short-term physical access can steal Wi‑Fi credentials via the USB interface. Sensitive data within the firmware configuration can be abused to gain root privileges on the device. Within Wi‑Fi coverage, the attacker may perform audio and video eavesdropping with no LED alert from the device.
