Authenticated SQL injection via custom-model import
Published Sep 22, 2026 · Updated Sep 22, 2026
SQL injection in MCMS 6.1.1 through 6.2.1 allows remote authenticated users to execute arbitrary SQL through a custom-model import. The importJson handler passes the imported sql field through ModelBizImpl.importModel to IBaseDao.excuteSql, which executes semicolon-delimited statements without filtering. Administrative backend access and a generated custom-business-form payload are required; successful exploitation permits direct database reads or writes.
