CVE-2023-28437Public exploitNetwork attack vector

Unauthenticated database disclosure via raw order clause

Published Mar 24, 2023 · Updated Feb 19, 2025

SQL injection in DataEase 1.18.4 and earlier allows remote attackers to extract database information through the orders parameter. ExtSysMsgMapper.xml inserts orderByClause with raw ${} substitution, while XssAndSqlHttpServletRequestWrapper applies an incomplete keyword blacklist that functions such as GTID_SUBSET bypass. The affected list endpoint requires no privileges, and its demonstrated error-based path discloses database-derived information through query errors.
