编写目的

批量验证poc，Python代码练习。

需求分析

1、poc尽可能简单。
2、多线程。
3、联动fofa获取目标。
4、随机请求头.

实现过程

脚本分为三个模块，获取poc及目标、多线程批量请求验证、输出结果。其中批量请求验证包括构造多线程，修改请求参数，发送请求三个部分。

Main函数

在main函数中，主要有三个部分获取poc及目标，多线程(将目标填充到队列，创建多线程并启动)、输出结果。
具体实现如下：

def main():
    # 响应Ctrl+C停止程序
    signal.signal(signal.SIGINT, quit)
    signal.signal(signal.SIGTERM, quit)
    showpocs() 

    ## 获取目标
    targetList = getTarget()

    ## 多线程批量请求验证
    thread(targetList)

    ## 输出结果
    putTarget(List)

获取目标

关于目标来源，设计单个目标、从文件中读取多个目标以及根据FoFa语法从FOFA_API中获取目标三种方式。

定义函数getTarget，函数分为两个部分

第一部分为根据 -f Fofa语法 获取目标，默认数目为30条，

第二部分为根据 -u url / -i file / -f num(数目，默认为10) 获取要请求验证的目标，两部分以是否传参poc参数区别，最后返回一个targetList列表。

具体实现如下：

def getTarget():
    targetList=[]
    count=0
    if result.poc==None:
        if result.outfile!=None and result.fofa!=None :
            # FOFA读取目标
            if result.fofa!=None:
                qbase=result.fofa
                qbase64=str(base64.b64encode(qbase.encode("utf-8")), "utf-8")
                print("FOFA搜索："+qbase)
                fofa_url="https://fofa.so/api/v1/search/all?email="+email+"&key="+key+"&qbase64="+qbase64+"&fields=title,host,ip,port,city&size=30"
                try:
                    res=requests.get




    
(fofa_url)
                    results = json.loads(res.text)
                    filepath=result.outfile
                    with open(filepath,'w') as targets:
                        for i in results['results']:
                            targets.write(i[1]+'\n')
                            print(i[1])
                            count+=1
                        print("搜索结果有"+str(count)+"条，已保存在"+filepath+"里！")
                except Exception as e:
                    print(e)
            sys.exit()
    else:
        if result.url!=None or result.file!=None or result.fofa!=None:
            # 单个目标




    
            if result.url!=None:
                targetList.append(result.url)
            # 文件读取目标
            if result.file!=None:
                try:
                    filepath=result.file
                    with open(filepath,'r') as targets:
                        for target in targets.readlines():
                           targetList.append(target.strip())
                except Exception as e:
                    print(e)
            # FOFA读取目标
            if result.fofa!=None:
                qbase=""
                pocName = result.poc
                with open('poc.json',encoding='UTF-8') as f:
                    data 




    
= json.load(f)
                    for poc in data:
                        if pocName == poc:
                            qbase=data[poc]['fofa']
                qbase64=str(base64.b64encode(qbase.encode("utf-8")), "utf-8")
                try:
                    fofa_url="https://fofa.so/api/v1/search/all?email="+email+"&key="+key+"&qbase64="+qbase64+"&fields=title,host,ip,port,city&size="+str(result.fofa)
                    res=requests.get(fofa_url)
                    results = json.loads(res.text)
                    print("FOFA搜索："+qbase)
                    print("搜索结果："+str(result.fofa)+"条")
                    for i in results['results']:
                        targetList.append(i[




    
1])
                    # print(targetList)
                except Exception as e:
                    print(e)
            return targetList
        else :
            sys.exit("参错有误！缺少目标！")

批量请求验证

定义thread函数，封装多线程请求相关代码，需传入获取到的目标参数targetList。
具体实现如下：

def thread(targetList):
    ## 获取poc
    poc=poc_load()

    ## 填充队列
    queueLock.acquire()
    for target in targetList:
        targetQueue.put(target)
    queueLock.release()

    ## 创建线程
    threadList = []
    threadNum=result.threadNum
    for i in range(0,threadNum):




    
        t=reqThread(targetQueue,poc)
        t.setDaemon(True)
        threadList.append(t)
    for i in threadList:
        i.start()

    # 等待所有线程完成
    for t in threadList:
        t.join()

加载POC

请求验证必须使用 -p pocName 参数指定要使用的POC，所有POC在poc.json文件中存储。

具体实现如下：

# 加载poc
def poc_load():
    if result.poc!=None:
        poc = result.poc
        isPoc = False # POC是否存在
        # 读取json文件
        with open('poc.json',encoding='UTF-8') as f:
            data =




    
 json.load(f)
            for key in data:
                if poc == key:
                    isPoc=True
        if isPoc==False:
            print("POC 不存在！")
            sys.exit("请通过--show查看poc列表！")
        else:
            return data[poc]
    else:
        pass

多线程类

定义reqThread线程类，传入队列以及poc两个参数，封装req请求方法。
具体实现如下：

class reqThread (threading.Thread):
    def __init__(self, q,poc):
        threading.Thread.__init__(self)
        self.q = q
        self.poc=poc
    def run(self):
        




    
try:
            while not self.q.empty():
                queueLock.acquire()
                target=self.q.get()
                queueLock.release()
                if self.req(target):
                    print(target+" is vuln !")
                    List.append(target)
                else:
                    pass
        except Exception as e:
            pass
    def req(self,url):
        poc=self.poc
        payload=urlParse(url)+poc['request']['url']
        res=requests.request(method=poc['request']['method'],url=payload,headers=




    
randomheaders(poc),proxies=getProxy(),data=poc['request']['data'],verify=False,timeout=5)
        if res.status_code==200 and poc['request']['confirm'] in res.text:
            return True
        else:
            return False

其中在req中的请求方法内，存在三个修改请求的方法。

urlParse

对获取到的目标进行文本处理。

# 处理url
def urlParse(url):
     if "https://" not in url:
        if "http://" in url:
            url=url
        else:
            url="http://"+url
     return url

getProxy

指定请求代理。

# 代理




    
def urlParse(url):
     if "https://" not in url:
        if "http://" in url:
            url=url
        else:
            url="http://"+url
     return url

randomHeaders

添加随机User-Agent、referer、XFF等请求头参数值。

def randomHeaders(poc):
    headers={}

输出结果

定义全局变量Li st，储存要输出的目标，定义输出方法putTarget。
具体实现如下：

List=[]
## 输出
def putTarget(resultList):
    if result.file!=None or result.fofa!=None:
        if len(resultList)!=0 :




    
            if result.outfile != None :
                filepath=result.outfile
                with open(filepath,'w') as targets:
                     for target in resultList:
                        targets.write(target+'\n')
                print("验证结果有"+str(len(resultList))+"条，已保存在"+filepath+"里！")
        else:
            print("没有发现存在漏洞的目标！")
    else:
        pass

poc.json文件

poc本质为一次HTTP请求，本着简单的原则，仅设计名称、联动fofa的语法、请求头、请求内容、以及验证漏洞存在回显的内容5个字段。

        "name":"漏洞描述",
                "fofa":"fofa搜索字符串，特殊符号需要转义",
        "request": {

            "headers": {
                "referer": "",
