Name of the Vulnerable Software and Affected Versions D-Link DI-8400 versions prior to 16.07.26A1

Description A stack-based buffer overflow occurs due to the manipulation of the str argument within the '/dbsrv.asp' endpoint. This allows for remote exploitation. A stack-based buffer overflow is a condition where a program writes more data to a buffer located on the stack than the buffer is allocated to hold, potentially leading to crashes or arbitrary code execution.

Recommendations Update to a version later than 16.07.26A1. As a temporary workaround, restrict access to the '/dbsrv.asp' endpoint to minimize the risk of exploitation.
