CVE-2025-8404Network attack vector

Authenticated code execution via crafted header overflow

Published Nov 18, 2025 · Updated Nov 18, 2025

Stack-based buffer overflow in Supermicro X13SEDW-F BMC firmware 01.03.48 allows remote authenticated users to execute code via a crafted header. Supermicro identifies the locus as a BMC shared library but has not disclosed the header parser or the specific unchecked operation that overruns its stack buffer. Administrative BMC access is required, and successful exploitation permits arbitrary code execution on the firmware operating system.
