D-Link Routers Unauthenticated RCE (CVE-2019-16920)

critical Nessus Plugin ID 166889


The remote router is affected by a remote code execution vulnerability.


The remote D-Link router is affected by a remote code execution vulnerability. 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.

Note that Nessus has not tested for this issue but has instead relied only on the router's self-reported model.


Upgrade to a supported device.
