3. VULNERABILITY DESCRIPTION

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.
