CVE-2024-37641Public exploitNetwork attack vector

Code execution or crash via unchecked sprintf

Published Jun 14, 2024 · Updated Aug 2, 2024

Stack overflow in TRENDnet TEW-814DAP firmware 1.01B01 allows remote authenticated users to execute code or crash the device. The formNewSchedule handler copies the submit-url value into stack buffer v14 with sprintf without checking its length. Access to the web management interface and a valid session are required; an oversized POST can corrupt control flow or interrupt service.
