SQL injection via subquery exception blacklist bypass
Published Aug 22, 2025 · Updated Aug 22, 2025
SQL injection in JeecgBoot 3.4.3 through 3.8.0 allows remote attackers to read database metadata through a crafted parseSql request. AbstractQueryBlackListHandler.isPass casts parsed subquery objects without checking their type, and the resulting exception leaves the table list null so blacklist validation returns true. The published request demonstrates access to database schema names; broader data access depends on the application's database account privileges.
