Detailed vulnerability description
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to improper input validation in the getJdbc function in H2.java when handling datasource validation requests. A remote attacker can send a specially crafted request to execute arbitrary code.
The issue arises because the check validates that jdbcUrl starts with "jdbc:h2" while the actual connection URL is taken from the separate jdbc field, allowing use of an arbitrary JDBC driver and connection URL.
