VirtualJDBC is an additional extension for SAP Hybris E-commerce. It is a kind of proxy for accessing RDBMS over HTTP.
So, there is an opportunity to run any SQL query in the DB remotely.
The VirtualJDBC servlet requires a valid credential, but it has a default one in a configuration file.
Also, it doesn’t have any protection against bruteforce attacks.
An attacker can use default credentials to get unauthorized access to the database and perform various actions in the system. It may have been implemented into the system as a backdoor.
