X-SpringBoot 6.0 RBAC Desynchronization Exploit

X-SpringBoot 6.0 is a Java-based web application framework used for building enterprise-level applications. The vulnerability arises from the implementation of role-based access control (RBAC) through dual dependency on frontend menu systems and backend permission tables, without enforcing atomic synchronization between these components. This fundamental flaw creates a dangerous desynchronization that allows attackers to perform privileged operations, including creating high-permission user accounts, accessing sensitive data beyond their clearance level, and executing admin-level commands.

Specific version info not stated in the advisory. If you don't recognise this software, you're probably not affected.

Concrete steps:

1. Upgrade to X-SpringBoot 7.0 or later (https://github.com/yzcheng90/X-SpringBoot/releases).
2. Immediate mitigations:
3. Restrict network access to your X-SpringBoot instance (firewall it from the public internet).
4. Audit admin account activity for suspicious access patterns.
5. Monitor for unauthorized token creation.
