## Overview

Northstar (dromara/northstar, quantitative trading platform) <= 9.1.1 enables the H2 Console but its auth interceptor only covers /northstar/**, so /h2-console is exposed with no authentication and the embedded H2 DB uses default sa / empty password. Any network-reachable attacker can run arbitrary system commands via CREATE ALIAS (pre-auth RCE).
