CVE-2026-7289 is a remotely exploitable buffer overflow vulnerability in D-Link DIR-825M firmware 1.1.12. The flaw is in function sub_414BA8 associated with the /boafrm/formWanConfigSetup endpoint. According to the provided content, the handler retrieves the HTTP parameter submit-url and copies it into a fixed-size stack buffer using strcpy without proper bounds checking. A crafted oversized submit-url value can overflow the stack and overwrite adjacent memory, potentially including control-flow data such as the saved return address. The issue is reachable over the network via an HTTP request to the affected endpoint, and public exploit information is available.
