|
|
This module abuses a file exposure vulnerability accessible through the web interface
|
|
on port 49152 of Supermicro Onboard IPMI controllers. The vulnerability allows an attacker
|
|
to obtain detailed device information and download data files containing the clear-text
|
|
usernames and passwords for the controller. In May of 2014, at least 30,000 unique IPs
|
|
were exposed to the internet with this vulnerability.
