Unauthenticated stack corruption via unchecked next_page copy
Published Mar 4, 2026 · Updated Mar 4, 2026
Stack buffer overflow in formDeviceReboot in D-Link DIR-513 1.10 allows remote attackers to corrupt process memory via a crafted next_page value. The handler copies the unbounded next_page form value through p_last_url with strcpy into a fixed-size stack buffer. No authentication or user interaction is required; the public artifact supplies a triggering request but does not demonstrate code execution.
