| Titre | D-Link DIR-823X 250416 OS Command Injection |
|---|
| Description | The D-Link DIR-823X router is susceptible to a Remote Command Injection vulnerability via the /goform/set_qos endpoint. The flaw exists in the backend function sub_420688, which fails to adequately filter the newline character (\n or 0x0A) when handling parameters such as qqos_enable, qqos_max_download, and qqos_max_upload. An authenticated attacker can inject arbitrary shell commands by using a newline to terminate the intended UCI configuration command and initiate a malicious instruction, which is then executed with root privileges. |
