Description

An issue was discovered on Supermicro BMC firmware in select X11, X12, H12, B12, X13, H13, and B13 motherboards (and CMM6 modules). An unauthenticated user can post crafted data to the interface that triggers a stack buffer overflow, and may lead to arbitrary remote code execution on a BMC.
