info:
  name: D-Link DIR-868L/817LW - Information Disclosure
  author: pikpikcu
  severity: critical
  description: |
    D-Link DIR-868L B1-2.03 and DIR-817LW A1-1.04 routers are vulnerable to information disclosure vulnerabilities because certain web interfaces do not require authentication. An attacker can get the router's username and password (and other information) via a DEVICE.ACCOUNT value for SERVICES in conjunction with AUTHORIZED_GROUP=1%0a to getcfg.php. This could be used to control the router remotely.
  impact: |
    An attacker can exploit this vulnerability to gain access to sensitive information, such as router configuration settings and credentials.
  remediation: |
    Apply the latest firmware update provided by D-Link to fix the information disclosure vulnerability.
