CMS识别(Web指纹识别)扫描器开发

February 3, 2019 • Read: 2018 • 渗透测试

CMS识别原理

CMS英文全称是:Content Management System,中文名称是:网站内容管理系统。CMS识别原理就是得到一些CMS的一些固有特征,通过得到这个特征来判断CMS的类别。

这里我们采用MD5识别和正则表达式识别的方式,具体来说就是用特定的文件路径访问网站,或者这个文件的MD5或者用正则表达式匹配某个关键词,如果匹配成功就说明是这个CMS。所以识别的成功率与字典有关

指纹格式

这里截取一些Web指纹作为参考:

{
    "url": "/install/",
    "re": "aspcms",
    "name": "AspCMS",
    "md5": ""
},
{
    "url": "/about/_notes/dwsync.xml",
    "re": "aspcms",
    "name": "AspCMS",
    "md5": ""
},
{
    "url": "/admin/_Style/_notes/dwsync.xml",
    "re": "aspcms",
    "name": "AspCMS",
    "md5": ""
},
{
    "url": "/apply/_notes/dwsync.xml",
    "re": "aspcms",
    "name": "AspCMS",
    "md5": ""
},
{
    "url": "/tpl/green/common/images/notebg.jpg",
    "re": "",
    "name": "自动发卡平台",
    "md5": "690f337298c331f217c0407cc11620e9"
},
{
    "url": "/images/download.png",
    "re": "",
    "name": "全程oa",
    "md5": "9921660baaf9e0b3b747266eb5af880f"
},
{
    "url": "/kindeditor/license.txt",
    "re": "",
    "name": "T-Site建站系统",
    "md5": "b0d181292c99cf9bb2ae9166dd3a0239"
},
{
    "url": "/public/ico/favicon.png",
    "re": "",
    "name": "悟空CRM",
    "md5": "834089ffa1cd3a27b920a335d7c067d7"
},
{
    "url": "/public/js/php/file_manager_json.php",
    "re": "",
    "name": "悟空CRM",
    "md5": "c64fd0278d72826eb9041773efa1f587"
},
{
    "url": "/plugins/weathermap/images/exclamation.png",
    "re": "",
    "name": "CactiEZ插件",
    "md5": "2e25cb083312b0eabfa378a89b07cd03"
}

指纹文件

data目录下存放data.json文件格式的Web指纹,总共有1400+的国内常见指纹,[下载地址]()

代码编写

思路虽然简单,但实现起来还有很多问题,比如效率,1000+指纹说明需要访问1000+的网页,单步的话速度太慢,所以需要使用多线程,等用多了也会发现多线程也太慢了,所以可以使用协程,以后再慢慢优化,这里就使用多线程就行了

新建文件lib/core/webcms.py,代码如下

# __author__ = 'mathor'
import json, os, sys, hashlib, threading, queue
from lib.core import Download

class webcms(object):
    workQueue = queue.Queue()
    URL = ""
    threadNum = 0
    NotFound = True
    Downloader = Download.Downloader()
    result = ""
    
    def __init__(self, url, threadNum = 10):
        self.URL = url
        self.threadNum = threadNum
        filename = os.path.join(sys.path[0], 'data', 'data.json')
        fp = open(filename, encoding = 'utf-8')
        webdata = json.load(fp, encoding = 'UTF-8')
        for i in webdata:
            self.workQueue.put(i)
        fp.close
        
    def getmd5(self, body):
        m2 = hashlib.md5()
        m2.update(body)
        return m2.hexdigest()
        
    def th_whatweb(self):
        if (self.workQueue.empty()):
            self.NotFound = False
            return False
    
        if (self.NotFound is False):
            return False
        cms = self.workQueue.get()
        _url = self.URL + cms['url']
        html = self.Downloader.get(_url)
        print("[whatweb log]:checking %s" % _url)
        if (html is None):
            return False
        if cms['re']:
            if (html.find(cms['re']) != -1):
                self.result = cms['name']
                self.NotFound = False
                return True
        else:
            md5 = self.getmd5(html)
            if (md5 == cms['md5']):
                self.result = cms['name']
                self.NotFound = False
                return True
    
    def run(self):
        while(self.NotFound):
            th = []
            for i in range(self.threadNum):
                t = threading.Thread(target = self.th_whatweb)
                t.start()
                th.append(t)
            for t in th:
                t.join()
        if (self.result):
            print("[webcms]:%s cms is %s" % (self.URL, self.result))
        else:
            print("[webcms]:%s cms NOTFound!" % self.URL)
