Unauthenticated username disclosure via differentiated login errors

Published Jul 19, 2024 · Updated Mar 18, 2025

Improper access control in lin-CMS Springboot 0.2.1 and earlier allows remote attackers to identify valid usernames through its login endpoint. The UserController login method returns distinct error conditions for an unknown username and an incorrect password, exposing whether the submitted account exists. No authentication or user interaction is required, and the disclosed information is limited to account-name validity rather than credentials or content.
