An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. They allow remote attackers to execute arbitrary commands via the date parameter in a system_time.cgi POST request. TRENDnet TEW-632BRP 1.010B32 is also affected.
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.
