Authenticated database data access via Username interpolation
Published Jun 27, 2025 · Updated Jun 27, 2025
SQL injection in huija bicycleSharingServer 7b8a3ba48ad618604abd4797d2e7cf3b5ac7625a allows remote authenticated users to read database data. The UserDao mapper expands Username inside the %${_parameter}% LIKE pattern, causing MyBatis to insert untrusted text into SQL instead of binding it as data. The GET route requires a JSESSIONID-backed authenticated session, and the published sqlmap test demonstrates retrieval of the database user name root.
