Thousands of servers running etcd are exposing user credentials publicly on the Internet. According to security researcher Giovanni Collazo, a quick query made through the Shodan search engine revealed a total of 2,284 etcd servers which are leaking credentials, including the passwords and keys required for cms_admin, mysql_root, and postgres server infrastructure.
Etcd is a type of database which allows for the storage of data by clustering. The open-source system is able to store the credentials required for different servers and applications, and as apps can read and write data into the management system, reconfiguration across servers and networks becomes a more streamlined process.
