Sensitive data disclosure via unsafe ORDER BY substitution
Published Jun 24, 2025 · Updated Jun 24, 2025
SQL injection in Novel-Plus 5.1.0 through 5.1.3 allows remote authenticated users to read sensitive user data through the user-list endpoint. UserMapper.xml inserts attacker-controlled sort and order values into the listByPerm ORDER BY clause through raw MyBatis text substitution. Access to the authenticated /sys/user/list route is required; injected queries can expose usernames, email addresses, and password hashes from sys_user.
