Researchers have disclosed a security flaw affecting H2 database consoles that could result in remote code execution in a manner that echoes the Log4j "Log4Shell" vulnerability that came to light last month.

The issue, tracked as CVE-2021-42392, is the " first critical issue published since Log4Shell, on a component other than Log4j, that exploits the same root cause of the Log4Shell vulnerability, namely JNDI remote class loading," JFrog researchers Andrey Polkovnychenko and Shachar Menashe said.

H2 is an open-source relational database management system written in Java that can be embedded within applications or run in a client-server mode.

"Similar to the Log4Shell vulnerability uncovered in early December, attacker-controlled URLs that propagate into JNDI lookups can allow unauthenticated remote code execution, giving attackers sole control over the operation of another person or organization's systems," Menashe, senior director of JFrog security research, explained.

The flaw affects H2 database versions 1.1.100 to 2.0.204 and has been addressed in version 2.0.206 shipped on January 5, 2022.

"The H2 database is used by many third-party frameworks, including Spring Boot, Play Framework and JHipster," Menashe added.
