CVE-2022-45207Public exploitNetwork attack vector

Database compromise via unvalidated field name substitution

Published Nov 25, 2022 · Updated Jul 9, 2026

SQL injection in JeecgBoot 3.4.3 allows remote attackers to execute attacker-controlled SQL through updateNullByEmptyString. The SysUserMapper.xml statement substitutes fieldName directly into a column assignment and WHERE clause instead of restricting it to approved columns. The published network assessment requires no authentication or user interaction, and successful injection can expose, alter, or disrupt database data.
