Title
Cudy WR3000 2.0 OS Command Injection via Mesh MQTT Command Handler
Summary
Cudy WR3000 2.0 running firmware before 2.5.24 contains an OS command injection vulnerability that allows authenticated attackers to execute arbitrary OS commands with root privileges by sending unsanitized input through the mesh MQTT command interface. The sync_command binary forwards unsanitized input directly to a shell execution sink in command.lua, enabling attackers with access to the MQTT broker to exploit the default-enabled command execution path to achieve full root-level system compromise.

Title
Cudy WR3000 2.0 Hard-coded JWT Secret Authentication Bypass via MQTT
Summary
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.

Title
Cudy WR3000 2.0 Hard-coded JWT Secret Authentication Bypass via MQTT
Summary
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.

Title
Cudy LT300 3.0 OS Command Injection via NTP Configuration
Summary
Cudy LT300 3.0 running firmware prior to version 2.5.12 contains an OS command injection vulnerability that allows authenticated attackers to execute arbitrary commands by injecting shell metacharacters into the cbid.system.ntp.current POST parameter in the system time configuration interface. Attackers can submit malicious payloads through the NTP settings endpoint to achieve remote code execution on the underlying system.
