Web-service crash via unchecked configuration length
Published Apr 6, 2021 · Updated Sep 16, 2024
Buffer overflow in ASUS BMC firmware's Active Directory configuration page allows remote authenticated users to crash the web service. The page accepts an overlong configuration string without checking its length before copying it into a fixed-size buffer. Exploitation requires privileged BMC web-interface access and interrupts only that management service; no data exposure or modification is reported.
