PatchTheCVECVE-2019-6260: The ASPEED ast2400 and ast2500 Baseband Management Controller (BMC) hardware and firmware implement Advanced H
CVE-2019-6260 is a critical-severity flaw (CVSS 9.8) affecting ast2400 firmware, ast2500 firmware, fas\/aff baseboard management controller. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
The ASPEED ast2400 and ast2500 Baseband Management Controller (BMC) hardware and firmware implement Advanced High-performance Bus (AHB) bridges, which allow arbitrary read and write access to the BMC's physical address space from the host (or from the network in unusual cases where the BMC console uart is attached to a serial concentrator). This CVE applies to the specific cases of iLPC2AHB bridge Pt I, iLPC2AHB bridge Pt II, PCIe VGA P2A bridge,
