Adjacent privilege escalation via BMC buffer overflow
Published Jun 9, 2021 · Updated Aug 3, 2024
Buffer overflow in Intel Server Board M10JNP2SB BMC firmware before 8100.01.08 allows remote attackers to escalate privileges. Intel identifies the affected locus only as BMC firmware and has not disclosed which input overruns which buffer or how the overwrite reaches privileged execution. Exploitation requires unauthenticated adjacent access; Intel reports privilege escalation but does not specify the resulting privilege level.
