CyberRota Analysis
AI-GeneratedCudy WR3000 2.0 devices running firmware prior to version 2.5.24 are vulnerable due to a hard-coded JWT HMAC signing secret in the Mosquitto MQTT broker's authentication plugin. This flaw allows unauthenticated attackers to extract the secret from the firmware and forge valid JWT tokens, enabling unauthorized access to the device's mesh networking interface. Organizations using affected devices should prioritize immediate firmware updates to mitigate this critical security risk.
Original NVD Description
Cudy WR3000 2.0 running firmware before 2.5.24 contains a hard-coded JWT HMAC signing secret vulnerability in the Mosquitto MQTT broker's authentication plugin that allows unauthenticated attackers to forge valid JWT tokens by extracting the secret from the firmware image. Attackers can use the extracted secret to craft arbitrary JWT tokens and authenticate to the MQTT broker without legitimate credentials, gaining unauthorized access to the device's mesh networking interface.
