CVE-2021-42392

Impact

H2 Console in versions since 1.1.100 (2008-10-14) to 2.0.204 (2021-12-21) inclusive allows loading of custom classes from remote servers through JNDI.

H2 Console doesn't accept remote connections by default. If remote access was enabled explicitly and some protection method (such as security constraint) wasn't set, an intruder can load own custom class and execute its code in a process with H2 Console (H2 Server process or a web server with H2 Console servlet).

It is also possible to load them by creation a linked table in these versions, but it requires ADMIN privileges and user with ADMIN privileges has full access to the Java process by design. These privileges should never be granted to untrusted users.

Patches

Since version 2.0.206 H2 Console and linked tables explicitly forbid attempts to specify LDAP URLs for JNDI. Only local data sources can be used.

Workarounds

H2 Console should never be available to untrusted users.

-webAllowOthers is a dangerous setting that should be avoided.

H2 Console Servlet deployed on a web server can be protected with a security constraint:
https://h2database.com/html/tutorial.html#usingH2ConsoleServlet
If webAllowOthers is specified, you need to uncomment and edit <security-role> and <security-constraint> as necessary. See documentation of your web server for more details.

CVE-2022-23221

H2 Console before 2.1.210 allows remote attackers to execute arbitrary code via a jdbc:h2:mem JDBC URL containing the IGNORE_UNKNOWN_SETTINGS=TRUE;FORBID_CREATION=FALSE;INIT=RUNSCRIPT substring, a different vulnerability than CVE-2021-42392.
