CVE-2025-10123 is a remote command injection vulnerability affecting D-Link DIR-823X routers running firmware up to and including version 250416. The flaw is present in the firmware function identified as sub_415028, which processes requests to the web management endpoint responsible for static DHCP lease configuration. By supplying a crafted value in the Hostname parameter of a POST request to the static lease configuration handler, an attacker can inject shell metacharacters that are unsafely incorporated into a system command. This results in arbitrary command execution on the device. The vulnerability stems from insufficient sanitization of user-controlled input before it is passed to command execution logic in the router firmware.
