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),so there may be security risks. Besides, we found that the SNMP of a few products has security risks and may be exploited by attackers in some extreme cases.
The affected products and corresponding update versions are shown in the table below.
