id: CVE-2023-31478

info:
  name: GL.iNET SSID Key Disclosure
  author: DhiyaneshDK
  severity: high
  description: |
    An issue was discovered on GL.iNet devices before 3.216. An API endpoint reveals information about the Wi-Fi configuration, including the SSID and key.
  impact: |
    Unauthenticated attackers can retrieve Wi-Fi SSID and password information through the mesh status API endpoint, potentially allowing unauthorized access to the wireless network and intercepting network traffic.
  remediation: |
    Update GL.iNET firmware to version 3.216 or later that requires authentication for the /api/router/mesh/status endpoint and protects Wi-Fi credentials.
