Description
A security vulnerability has been detected in D-Link DIR-823X 250416. This issue affects some unknown processing of the file /goform/set_ddns of the component DDNS Service. The manipulation of the argument ddnsType/ddnsDomainName/ddnsUserName/ddnsPwd leads to os command injection. The attack is possible to be carried out remotely. The exploit has been disclosed publicly and may be used.
A remote command injection vulnerability has been identified in the D-Link DIR-823X router, specifically in version 250416. The issue arises in the DDNS (Dynamic DNS) service component, within the file '/goform/set_ddns'. The vulnerability allows authenticated attackers to inject arbitrary operating system commands through several parameters, including ddnsType, ddnsDomainName, ddnsUserName, and ddnsPwd. This exploitation is possible due to inadequate input sanitization that fails to remove newline characters, enabling the injection of commands that are executed with root privileges via the system shell.
No specific remediation is known for this vulnerability.
