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.

Affected configurations

• dlink dir-655 firmware (<= 3.02b05) • dlink dir-866l firmware (<= 1.03b04) • dlink dir-652 firmware • dlink dhp-1565 firmware (<= 1.01) • dlink dir-855l firmware • dlink dap-1533 firmware • dlink dir-862l firmware • dlink dir-615 firmware • dlink dir-835 firmware • dlink dir-825 firmware
