Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-94.
Summary
Northstar, the dromara/northstar quantitative trading platform, is affected up to and including 9.1.1. Its authentication interceptor covers only /northstar/**, so the enabled H2 Console at /h2-console requires no login, and the embedded H2 database uses the default sa account with an empty password. A network-reachable attacker can exploit improper control of code generation (CWE-94) to run arbitrary system commands without authentication.

Description from the CNA
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).
