D-Link Multiple Routers Command Injection Vulnerability
Cos'è
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.
CISA: Multiple D-Link routers contain a command injection vulnerability which can allow attackers to achieve full system compromise.
Cosa fare
The impacted product is end-of-life and should be disconnected if still in use.
