Password exposure in H2 Database

The web-based admin console in H2 Database Engine through 2.1.214 can be started via the CLI with the argument -webAdminPassword, which allows the user to specify the password in cleartext for the web admin console. Consequently, a local user (or an attacker that has obtained local access through some means) would be able to discover the password by listing processes and their arguments. NOTE: the vendor states “This is not a vulnerability of H2 Console … Passwords should never be passed on the command line and every qualified DBA or system administrator is expected to know that.”
