CVE-2025-10666 is a remotely exploitable buffer overflow in D-Link DIR-825 routers affecting firmware up to version 2.10. The flaw is in the apply.cgi component, specifically function sub_4106d4, where manipulation of the countdown_time argument can cause memory corruption due to improper bounds handling during processing of attacker-controlled input. Public reporting identifies this as part of a broader pattern of memory-safety issues in the DIR-825 web management stack. The vulnerable condition is reachable over the device’s HTTP management interface, and a public exploit has been released. The affected DIR-825 hardware revisions are legacy/end-of-support products, and the vendor states no fixed firmware is available for the impacted legacy revisions.
