CVE-2018-10054 (opens in a new tab)Amendment
This was deemed not a vulnerability.
Overview
com.h2database:h2 is a database engine
Affected versions of this package are vulnerable to Remote Code Execution (RCE). It provides a web console for managing the database, and by default it does not have a password set. The CREATE ALIAS function calls Java code, allowing an attacker to execute arbitrary Java code on projects running the h2 database.
NOTE: To be remotely exploitable, the affected application must be configured with the non-default setting webAllowOthers=true, either in a config file or as a parameter passed in when the servlet is invoked. The vulnerability can be avoided by setting a password on the database and/or restricting access to localhost using the above setting.
PoC
CREATE ALIAS REVERSE AS $$ String reverse(String s) { return new StringBuilder(s).reverse().toString(); } $$;
CALL REVERSE('Test');
