| 제목 | D-Link DIR-823X 250416 OS Command Injection |
|---|
| 설명 | The D-Link DIR-823X router is susceptible to a Remote Command Injection vulnerability via the /goform/set_upnp endpoint. The flaw exists in the backend function sub_420618, which fails to adequately filter the newline character (\n or 0x0A) when handling the upnp_enable parameter.
An authenticated attacker can inject arbitrary shell commands by using a newline to terminate the intended UCI configuration command and initiate a malicious instruction. These commands are subsequently executed with root privileges. |
