IP.Board<=3.4.7 SQL注入漏洞（0day）POC
近日IP.Board <= 3.4.7爆出重要0day漏洞。IPB论坛全称为Invision Power Board（缩写为IPB或IP.Board），是世界上最著名的论坛程序之一，由PHP+MySQL架构。
漏洞成因是酱紫的，interface/ipsconnect/ipsconnect.php页面的没有正确处理id参数。导致网站出现sql error，漏洞会把sql error写入/cache/sql_error_latest.cgi。通过不断遍历读取数据，可以获取到相应敏感信息。
漏洞POC（仅供网站安全验证，禁止非法用途）

# you can adapt to other types of blind injection if 'cache/sql_error_latest.cgi' is unreadable
