Python实现E-Mail收集插件

February 2, 2019 • Read: 439 • 渗透测试

__import__函数

我们都知道import是导入模块的,但是其实import实际上是使用builtin函数import来工作的。在一些程序中,我们可以动态去调用函数,如果我们知道模块的名称(字符串)的时候,我们可以很方便的使用动态调用

def getfunctionbyname(module_name, function_name):
    module = __import__(module_name)
    return getattr(module, function_name)

通过这段代码,我们就可以简单调用一个模块的函数了

插件系统开发流程

一个插件系统运转工作,主要进行以下几个方面的操作

  1. 获取插件,通过对一个目录里的.py文件扫描得到
  2. 将插件目录加入到环境变量sys.path
  3. 爬虫将扫描好的URL和网页源码传递给插件
  4. 插件工作,工作完毕后将主动权还给扫描器

插件系统代码

lib/core/plugin.py中创建一个spiderplus类,实现满足我们要求的代码

# __author__ = 'mathor'

import os
import sys
class spiderplus(object):
    def __init__(self, plugin, disallow = []):
        self.dir_exploit = []
        self.disallow = ['__init__']
        self.disallow.extend(disallow)
        self.plugin = os.getcwd() + '/' + plugin
        sys.path.append(plugin)
    
    def list_plusg(self):
        def filter_func(file):
            if not file.endswith('.py'):
                return False
            for disfile in self.disallow:
                if disfile in file:
                    return False
            return True
        dir_exploit = filter(filter_func, os.listdir(self.plugin)
        return list(dir_exploit)
        
    def work(self, url, html):
        for _plugin in self.list_plusg():
            try:
                m = __import__(_plugin.split('.')[0])
                spider = getattr(m, 'spider')
                p = spider()
                s = p.run(url, html)
            except Exception as e:
                print (e)

work函数中需要传递url,html,这个就是我们扫描器传给插件系统的,通过代码

spider = getattr(m, 'spider')
p = spider()
s = p.run(url, html)

我们定义插件必须使用class spider中的run方法调用

扫描器中调用插件

我们主要用爬虫调用插件,因为插件需要传递url和网页源码这两个参数,所以我们在爬虫获取到这两个的地方加入插件系统代码即可

首先打开Spider.py,在Spider.py文件开头加上

from lib.core import plugin

然后在文件的末尾加上

disallow = ['sqlcheck']
_plugin = plugin.spiderplus('script', disallow)
_plugin.work(_str['url'], _str['html'])

disallow是不允许的插件列表,为了方便测试,我们可以把sqlcheck填上

SQL注入融入插件系统

其实非常简单,只需要修改script/sqlcheck.py为下面即可

关于Download模块,其实就是Downloader模块,把Downloader.py复制一份命名为Download.py就行

import re, random
from lib.core import Download

class spider:
    def run(self, url, html):
        if (not url.find("?")): # Pseudo-static page
            return false;
        Downloader = Download.Downloader()
        BOOLEAN_TESTS = (" AND %d=%d", " OR NOT (%d=%d)")
        DBMS_ERRORS = {
            # regular expressions used for DBMS recognition based on error message response
            "MySQL": (r"SQL syntax.*MySQL", r"Warning.*mysql_.*", r"valid MySQL result", r"MySqlClient\."),
            "PostgreSQL": (r"PostgreSQL.*ERROR", r"Warning.*\Wpg_.*", r"valid PostgreSQL result", r"Npgsql\."),
            "Microsoft SQL Server": (r"Driver.* SQL[\-\_\ ]*Server", r"OLE DB.* SQL Server", r"(\W|\A)SQL Server.*Driver", r"Warning.*mssql_.*", r"(\W|\A)SQL Server.*[0-9a-fA-F]{8}", r"(?s)Exception.*\WSystem\.Data\.SqlClient\.", r"(?s)Exception.*\WRoadhouse\.Cms\."),
            "Microsoft Access": (r"Microsoft Access Driver", r"JET Database Engine", r"Access Database Engine"),
            "Oracle": (r"\bORA-[0-9][0-9][0-9][0-9]", r"Oracle error", r"Oracle.*Driver", r"Warning.*\Woci_.*", r"Warning.*\Wora_.*"),
            "IBM DB2": (r"CLI Driver.*DB2", r"DB2 SQL error", r"\bdb2_\w+\("),
            "SQLite": (r"SQLite/JDBCDriver", r"SQLite.Exception", r"System.Data.SQLite.SQLiteException", r"Warning.*sqlite_.*", r"Warning.*SQLite3::", r"\[SQLITE_ERROR\]"),
            "Sybase": (r"(?i)Warning.*sybase.*", r"Sybase message", r"Sybase.*Server message.*"),
        }
        _url = url + "%29%28%22%27"
        _content = Downloader.get(_url)
        for (dbms, regex) in ((dbms, regex) for dbms in DBMS_ERRORS for regex in DBMS_ERRORS[dbms]):
            if (re.search(regex,_content)):
                return True
        content = {}
        content['origin'] = Downloader.get(_url)
        for test_payload in BOOLEAN_TESTS:
            # Right Page
            RANDINT = random.randint(1, 255)
            _url = url + test_payload % (RANDINT, RANDINT)
            content["true"] = Downloader.get(_url)
            _url = url + test_payload % (RANDINT, RANDINT + 1)
            content["false"] = Downloader.get(_url)
            if content["origin"] == content["true"] != content["false"]:
                return "sql found: %" % url 

E-Mail搜索插件

最后一个简单的例子,搜索网页中的E-Mail,因为插件系统会传递网页源码,我们用一个正则表达式([\w-]+@[\w-]+\.[\w-]+)+搜索出所有的邮件。创建script/email_check.py文件

# __author__ = 'mathor'

import re
class spider():
    def run(self, url, html):
        #print(html)
        pattern = re.compile(r'([\w-]+@[\w-]+\.[\w-]+)+')
        email_list = re.findall(pattern, html)
        if (email_list):
            print(email_list)
            return True
        return False

运行python w8ay.py

可以看到网页中的邮箱都被采集到了
