Simply telnet to the IPMI IP Address in port 49152 and do a specific GET request. You should get your users and passwords if you're compromised.

telnet 49152

After the connection ask for GET /PSBlock and watch the results, it should be something like this:

Connected to
Escape character is '^]'.
GET /PSBlock



To solve this issue update the IPMI firmware to the latest version. The firmware is specific to your IPMI controller, so you should get the specified in Supermicro website.

Then after updating the firmware change your passwords.
