Web-service crash via unchecked certificate string length
Published Apr 6, 2021 · Updated Sep 16, 2024
Buffer overflow in ASUS BMC firmware allows remote authenticated users to crash its web service through the certificate-generation page. The certificate-generation function accepts a user-supplied string without checking its length before copying it into a fixed-size buffer. Administrative access to the BMC web interface is required, and exploitation terminates that management web service without reported data disclosure or modification.
