Web service crash via unchecked storage string
Published Apr 6, 2021 · Updated Sep 17, 2024
Buffer overflow in ASUS BMC firmware's remote video storage function allows remote authenticated users to crash the Web service. The Web management handler accepts an overlong remote-storage string without checking its length before copying it into a fixed-size buffer. Administrative privileges are required, and the documented consequence is termination of the BMC Web service rather than code execution.
