What is CVE-2019-16920?
CVE-2019-16920 is a critical command injection vulnerability in n/a, published on 27 Sep 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
