CVE-2023-37924Network attack vector

Unauthenticated Workbench access via MyBatis username interpolation

Published Nov 22, 2023 · Updated Aug 2, 2024

SQL injection in Apache Submarine 0.7.0 allows remote attackers to bypass login and access Workbench through a crafted username. The SysUserMapper MyBatis LIKE clause embeds userName directly with ${userName}, allowing quotes and Boolean operators to alter the query. The login interface requires no prior authentication, and a successful predicate bypass returns a user record that grants Workbench access.
