Well this is bad news. Via At least 32,000 servers broadcast admin passwords in the clear, advisory warns :
The threat resides in the baseboard management controller BMC, a motherboard component that allows administrators to monitor the physical status of large fleets of servers, including their temperatures, disk and memory performance, and fan speeds. Unpatched BMCs in Supermicro motherboards contain a binary file that stores remote login passwords in clear text. Vulnerable systems can be detected by performing an Internet scan on port 49152. A recent query on the Shodan search engine indicated there are 31,964 machines still vulnerable, a number that may not include many virtual machines used in shared hosting environments.
Patch and reboot!
