Severity ?
8.7 (High) - CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CWE
  • CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
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.

CWE
  • CWE-798 - Use of Hard-coded Credentials
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.
