|---|
| विवरण | D-Link DIR-823X routers are susceptible to a Remote Command Injection vulnerability via the /goform/set_ddns endpoint. The flaw exists in the backend handling of DDNS (Dynamic DNS) configuration parameters.
Due to an incomplete sanitization mechanism that fails to filter newline characters (\n or 0x0A), an authenticated attacker can inject arbitrary shell commands through parameters such as ddnsType, ddnsDomainName, ddnsUserName, or ddnsPwd. When the system commits these configurations to the UCI (Unified Configuration Interface) and restarts the DDNS service, the injected commands are executed with root privileges via the system shell. |
