Unprotected Exposed Firebird Database with default credentials

An unauthenticated attacker with access to the local network of the
medical office can use known default credentials to gain remote DBA
access to the Elefant Firebird database. The data in the database
includes patient data and login credentials among other sensitive data.
In addition, this enables an attacker to create and overwrite arbitrary
files on the server filesystem with the rights of the Firebird database
("NT AUTHORITY\SYSTEM").
