| 标题 | D-Link DIR-823X 250416 OS Command Injection |
|---|
| 描述 | The D-Link DIR-823X router is vulnerable to a Remote Command Injection vulnerability via the /goform/set_filtering endpoint. This vulnerability exists in the backend function sub_4211C8. The root cause is an insufficient security validation of user-supplied parameters (ipaddr, macaddr, urladdr, and name).
By using the newline character (\n or 0x0A), an authenticated attacker can bypass a shallow blacklist filter to terminate an intended uci set command and execute arbitrary shell commands with root privileges. |
