巡风源码阅读与分析---view.py

巡风是一款适用于企业内网的漏洞快速应急、巡航扫描系统，通过搜索功能可清晰的了解内部网络资产分布情况，并且可指定漏洞插件对搜索结果进行快速漏洞检测并输出结果报表。

环境：

巡风是基于python的flask框架写的，数据库为mongodb。

可安装在Windows OSX Linux Docker

Python2.7 pip mongodb

安装：

我安装在window，用于简单阅读代码和调试。

https://github.com/ysrc/xunfeng

下载后跟着官网的window安装教程即可。

然后运行 Run.bat （得使用管理员运行，不然没反应。。）

安装成功。

阅读:

使用的ide为pycharm
Run.bat

mogod.exe 用于启动mongodb

Run.py 启动web网站

Aider.py  # 辅助验证脚本

VulScan.py  # 漏洞检测引擎

NAScan.py  # 网络资产信息抓取引擎

Run.py

from views.View import app

if __name__ == '__main__':
    #app.debug = True
    app.run(threaded=True, port=8888,host='')

去到views/View.py

一共有24个方法。

一个方法一个方法来看。

1.Search()

# 搜索页
@app.route('/filter')
@logincheck
def Search():
    return render_template('search.html')

@logincheck 使用了装饰器函数。跟过去查看views/lib/Login.py

# 登录状态检查
def logincheck(f):
    @wraps(f)
    def wrapper(*args, **kwargs):
        try:
            if session.has_key('login'):
                if session['login'] == 'loginsuccess':
                    return f(*args, **kwargs)
                else:
                    return redirect(url_for('Login'))
            else:
                return redirect(url_for('Login'))
        except Exception, e:
            print e
            return redirect(url_for('Error'))

    return wrapper

如果seesion中的login等于loginsuccess 就继续执行view.py下的函数。否则跳转掉Error模板。就是检测是否有登录。

回到Search()加载search.html模板

2.Deleteall()

# 删除所有
@app.route('/deleteall', methods=['post'])
@logincheck
@anticsrf
def Deleteall():
    Mongo.coll['Task'].remove({})
    return 'success'

先判断了登录状态，多了一个@anticsrf 装饰器函数。跟过去查看views/lib/AntiCSRF.py

# 检查referer
def anticsrf(f):
    @wraps(f)
    def wrapper(*args, **kwargs):
        try:
            if request.referrer and request.referrer.replace('http://', '').split('/')[0] == request.host:
                return f(*args, **kwargs)
            else:
                return redirect(url_for('NotFound'))
        except Exception, e:
            print e
            return redirect(url_for('Error'))

    return wrapper

判断是否有referrer头，而且将http://替换成空 再分割取第一部分，也就是取出网站的host，然后与本站host相比较。看是否一致。不一样的话，跳转404页面。否则就继续执行。

@anticsrf 就是防止CSRF漏洞的。

回到Deleteall()

Mongo 跟过去发现是连接mongoDB。选择Task这个数据表，移除所有数据。

就是将任务总数全部删除。

3.Main()

# 搜索结果页
@app.route('/')
@logincheck
def Main():
    q = request.args.get('q', '')
    page = int(request.args.get('page', ''))
    plugin = Mongo.coll['Plugin'].find()  # 插件列表
    plugin_type = plugin.distinct('type')  # 插件类型列表
    if q:  # 基于搜索条件显示结果
        result = q.strip().split(';')
        query = querylogic(result)
        cursor = Mongo.coll['Info'].find(query).sort('time', -1).limit(page_size).skip((page - 1) * page_size)
        return render_template('main.html', item=cursor, plugin=plugin, itemcount=cursor.count(),
                               plugin_type=plugin_type, query=q)
    else:  # 自定义，无任何结果，用户手工添加
        return render_template('main.html', item=[], plugin=plugin, itemcount=0, plugin_type=plugin_type)

判断是否登录（下同）

先获取传入的q 和page 。

plugin = Mongo.coll['Plugin'].find()  #连接数据库，列出Plugin中所有清单。

plugin_type = plugin.distinct('type') #从查询的所有清单里面获取名字是 type的数据。

然后将q进行分割“；”主要是分割类似这种的 q= 127.0.0.1;127.8.8.1

分成列表传入querylogic()函数。 跟过去看看views/lib/QueryLogic.py（详细：https://www.cnblogs.com/zhengjim/p/9406065.html）

将搜索的值q转成mongoDB能查询的语句。

cursor = Mongo.coll['Info'].find(query).sort('time', -1).limit(page_size).skip((page - 1) * page_size)

在info表里把条件代入查询sort()排序 limit()分页

最后传给视图

4.Getplugin()

# 获取插件信息异步
@app.route('/getplugin', methods=['get', 'post'])
@logincheck
def Getplugin():
    type = request.form.get('type', '')
    risk = request.form.get('risk', '')
    search = request.form.get('search', '')
    query = {}
    if type:
        query['type'] = type
    if risk:
        query['level'] = risk
    if search:
        search = unquote(search)
        query['name'] = {"$regex": search, '$options': 'i'}
    cursor = Mongo.coll['Plugin'].find(query)
    rsp = []
    for i in cursor:
        result = {'name': i['name'], 'info': i['info']}
        rsp.append(result)
    return json.dumps(rsp)

获取了type risk search 是否有值

没有的话，就全部查询。有的话 在Plugin表代入条件查询。然后将插件名字和信息转json格式返回。

5.Addtask()

# 新增任务异步
@app.route('/addtask', methods=['get', 'post'])
@logincheck
@anticsrf
def Addtask():
    title = request.form.get('title', '')
    plugin = request.form.get('plugin', '')
    condition = unquote(request.form.get('condition', ''))
    plan = request.form.get('plan', 0)
    ids = request.form.get('ids', '')
    isupdate = request.form.get('isupdate', '')
    resultcheck = request.form.get('resultcheck', '')
    result = 'fail'
    if plugin:
        targets = []
        if resultcheck == 'true':  # 结果集全选
            list = condition.strip().split(';')
            query = querylogic(list)
            cursor = Mongo.coll['Info'].find(query)
            for i in cursor:
                tar = [i['ip'], i['port']]
                targets.append(tar)
        else:  # 当前页结果选择
            for i in ids.split(','):
                tar = [i.split(':')[0], int(i.split(':')[1])]
                targets.append(tar)
        temp_result = True
        for p in plugin.split(','):
            query = querylogic(condition.strip().split(';'))
            item = {'status': 0, 'title': title, 'plugin': p, 'condition': condition, 'time': datetime.now(),
                    'target': targets, 'plan': int(plan), 'isupdate': int(isupdate), 'query': dumps(query)}
            insert_reuslt = Mongo.coll['Task'].insert(item)
            if not insert_reuslt:
                temp_result = False
        if temp_result:
            result = 'success'
    return result

先获取了页面传了的值 先默认result为fail

没有plugin的话直接返回fail

有的话，先判断结果集是否全选，将结果集的ip和port都加入列表，否则将当前页的ip将入列表。 然后执行插入。成功返回success

6.Task()

# 任务列表页面
@app.route('/task')
@logincheck
def Task():
    page = int(request.args.get('page', ''))
    cursor = Mongo.coll['Task'].find().sort('time', -1).limit(page_size).skip((page - 1) * page_size)
    return render_template('task.html', item=cursor)

查询出任务信息，展示。

7.Recheck()

# 复测任务异步
@app.route('/taskrecheck')
@logincheck
@anticsrf
def Recheck():
    tid = request.args.get('taskid', '')
    task = Mongo.coll['Task'].find_one({'_id': ObjectId(tid)})
    result = 'fail'
    if task and task['plan'] == 0 and task['status'] == 2:  # 一次性任务，并且已经扫描完成
        result = Mongo.coll['Task'].update({'_id': ObjectId(tid)}, {'$set': {'status': 0}})
        if result:
            result = 'success'
    return result

找到任务后，判断扫描完成后，更新数据库。返回success。

8.TaskDetail()

# 任务详情页面
@app.route('/taskdetail')
@logincheck
def TaskDetail():
    id = request.args.get('taskid', '')
    page = int(request.args.get('page', ''))
    taskdate = request.args.get('taskdate', "")
    plugin_name = ''
    task_info = Mongo.coll['Task'].find_one({'_id': ObjectId(id)})
    if task_info:
        plugin_name = task_info['plugin']
    vulcount = 0
    lastscan = Mongo.coll["Result"].distinct('task_date', {'task_id': ObjectId(id)})
    result_list = []
    if len(lastscan) > 0:
        lastscan.sort(reverse=True)
        if taskdate:  # 根据扫描批次查看结果
            cursor = Mongo.coll['Result'].find(
                {'task_id': ObjectId(id), 'task_date': datetime.strptime(taskdate, "%Y-%m-%d %H:%M:%S.%f")}).sort(
                'time', -1).limit(page_size).skip((page - 1) * page_size)
        else:  # 查看最新批次结果
            taskdate = lastscan[0].strftime("%Y-%m-%d %H:%M:%S.%f")
            cursor = Mongo.coll['Result'].find(
                {'task_id': ObjectId(id), 'task_date': lastscan[0]}).sort('time', -1).limit(page_size).skip(
                (page - 1) * page_size)
        vulcount = cursor.count()
        for _ in cursor:
            result_list.append(
                {'ip': _['ip'], 'port': _['port'], 'info': _['info'], 'vul_level': _['vul_info']['vul_level'],
                 'time': _['time']})

        # 速度优化，数据量多采取不同的方式查询
        if len(result_list) > 100:
            ip_hostname = {}
            hostname = Mongo.coll['Info'].aggregate(
                [{'$match': {'hostname': {'$ne': None}}}, {'$project': {'_id': 0, 'ip': 1, 'hostname': 1}}])
            for _ in hostname:
                if 'hostname' in hostname:
                    ip_hostname[_["ip"]] = _["hostname"]
            for _ in result_list:
                if 'ip' in ip_hostname:
                    _['hostname'] = ip_hostname[_["ip"]]
                else:
                    _['hostname'] = ''
        else:
            for _ in result_list:
                hostname = Mongo.coll['Info'].find_one({'ip': _['ip']})
                if hostname and 'hostname' in hostname:
                    _['hostname'] = hostname['hostname']
                else:
                    _['hostname'] = ''
    return render_template('detail.html', item=result_list, count=vulcount, id=id, taskdate=taskdate,
                           plugin_name=plugin_name, scanlist=lastscan)

通过id找到任务详情，然后将详情展示出来。有taskdate就是可以查询指定的日期。没有这个参数就是查询最新日期。当结果大于100，使用优化的查询语句。

9.DeleteTask()

# 删除任务异步
@app.route('/deletetask', methods=['get', 'post'])
@logincheck
@anticsrf
def DeleteTask():
    oid = request.form.get('oid', '')
    if oid:
        result = Mongo.coll['Task'].delete_one({'_id': ObjectId(oid)})
        if result.deleted_count > 0:
            result = Mongo.coll['Result'].delete_many({'task_id': ObjectId(oid)})
            if result:
                return 'success'
    return 'fail'

删除任务操作

10.Downloadxls()

# 下载excel报表异步
@app.route('/downloadxls', methods=['get', 'post'])
@logincheck
@anticsrf
def DownloadXls():
    tid = request.args.get('taskid', '')
    taskdate = request.args.get('taskdate', '')
    result_list = []
    if tid:  # 有任务id
        if taskdate:  # 从任务中拉取指定批次扫描结果
            taskdate = datetime.strptime(taskdate, "%Y-%m-%d %H:%M:%S.%f")
            cursor = Mongo.coll['Result'].find({'task_id': ObjectId(tid), 'task_date': taskdate}).sort(
                'time', -1)
        else:  # 从任务中直接取该任务最新一次扫描结果
            lastscan = Mongo.coll["Result"].distinct('task_date', {'task_id': ObjectId(tid)})
            if len(lastscan) == 0:
                cursor = []
                taskdate = datetime.now()
            else:
                lastscan.sort(reverse=True)
                taskdate = lastscan[0]
                cursor = Mongo.coll['Result'].find({'task_id': ObjectId(tid), 'task_date': taskdate}).sort(
                    'time', -1)
        title = Mongo.coll['Task'].find_one({'_id': ObjectId(tid)})['title']
        for _ in cursor:
            hostname = ''
            result = Mongo.coll['Info'].find_one({'ip': _['ip']})
            if result and 'hostname' in result:
                hostname = result['hostname']
            result_list.append(
                {'ip': _['ip'], 'port': _['port'], 'info': _['info'], 'vul_level': _['vul_info']['vul_level'],
                 'time': _['time'], 'vul_name': _['vul_info']['vul_name'], 'lastscan': taskdate, 'title': title,
                 'hostname': hostname})
        response = make_response(CreateTable(result_list, taskdate.strftime("%Y%m%d-%H%M%S")))
        if taskdate == '':
            response.headers["Content-Disposition"] = "attachment; filename=nodata.xls;"
        else:
            response.headers["Content-Disposition"] = "attachment; filename=" + quote(
                title.encode('utf-8')) + taskdate.strftime(
                "%Y-%m-%d-%H-%M-%S") + ".xls;"
    else:  # 下载综合报表
        tasks = Mongo.coll['Task'].find({})
        t_list = []
        for t in tasks:
            name = t['title']
            lastscan = Mongo.coll["Result"].distinct('task_date', {'task_id': t['_id']})
            if len(lastscan) == 0:
                cursor = Mongo.coll['Result'].find({'task_id': t['_id']})
                taskdate = None
            else:
                lastscan.sort(reverse=True)
                taskdate = lastscan[0]
                cursor = Mongo.coll['Result'].find({'task_id': t['_id'], 'task_date': taskdate})
            for _ in cursor:  # 单任务详情
                hostname = Mongo.coll['Info'].find_one({'ip': _['ip']})
                if hostname:
                    _['hostname'] = hostname['hostname']
                else:
                    _['hostname'] = None
                _['title'] = name
                _['vul_level'] = _['vul_info']['vul_level']
                _['vul_name'] = _['vul_info']['vul_name']
                _['lastscan'] = taskdate
                t_list.append(_)
        response = make_response(CreateTable(t_list, 'all_data'))
        response.headers["Content-Disposition"] = "attachment; filename=all_data.xls;"
    response.headers["Content-Type"] = "application/x-xls"
    return response

216-243行 将扫描结果查询出来后加到result_list

response = make_response(CreateTable(result_list, taskdate.strftime("%Y%m%d-%H%M%S")))

跟CreateTable（）函数  View/lib/CreateExcel.py

def CreateTable(cursor, id):
    item = []
    item.append(['IP', '端口', '主机名', '风险等级', '漏洞描述', '插件类型', '任务名称', '时间', '扫描批次'])
    for i in cursor:
        if i['lastscan']:
            _ = [i['ip'], i['port'], i['hostname'], i['vul_level'], i['info'],
                 i['vul_name'], i['title'], i['time'].strftime('%Y-%m-%d %H:%M:%S'),
                 i['lastscan'].strftime('%Y-%m-%d %H:%M:%S')]
        else:
            _ = [i['ip'], i['port'], i['hostname'], i['vul_level'], i['info'],
                 i['vul_name'], i['title'], i['time'].strftime('%Y-%m-%d %H:%M:%S'), '']
        item.append(_)
    file = write_data(item, id)
    return file.getvalue()

创建个列表，将数据加入列表和描述对应起来。write_data()函数

def write_data(data, tname):
    file = xlwt.Workbook(encoding='utf-8')
    table = file.add_sheet(tname, cell_overwrite_ok=True)
    l = 0
    for line in data:
        c = 0
        for _ in line:
            table.write(l, c, line[c])
            c += 1
        l += 1
    sio = StringIO.StringIO()
    file.save(sio)
    return sio

通过xlwt包，将数据一行行写到文件里， 然后保存，文件名为时间格式。

回到view/view.py

make_response()返回文件名。 245-250行设置了http头和下载文件名字。后面返回下载。

251-277行同上。

11.search_result_xls()

看了页面回来看代码，这个方法就是将数据库中的值查询出来然后显示，不具体分析语句。

16.Config()

# 配置页面
@app.route('/config')
@logincheck
def Config():
    val = []
    table = request.args.get('config', '')
    if table in ("vulscan", "nascan"):
        dict = Mongo.coll['Config'].find_one({'type': table})
        if dict and 'config' in dict:
            dict = dict['config']
            for _ in dict:
                if _.find('_') > 0:
                    item_type = "list"
                else:
                    item_type = "word"
                val.append({"show": item_type, "type": _, "info": dict[_]["info"], "help": dict[_]["help"],
                            "value": dict[_]["value"]})
    val = sorted(val, key=lambda x: x["show"], reverse=True)
    return render_template('config.html', values=val)

判断是爬虫引擎还是扫描引擎，然后分别查询出数据。

17.UpdateConfig()

# 配置更新异步
@app.route('/updateconfig', methods=['get', 'post'])
@logincheck
@anticsrf
def UpdateConfig():
    rsp = 'fail'
    name = request.form.get('name', 'default')
    value = request.form.get('value', '')
    conftype = request.form.get('conftype', '')
    if name and value and conftype:
        if name == 'Masscan' or name == 'Port_list':
            origin_value = Mongo.coll['Config'].find_one({'type': 'nascan'})["config"][name]["value"]
            value = origin_value.split('|')[0] + '|' + value
        elif name == 'Port_list_Flag':
            name = 'Port_list'
            origin_value = Mongo.coll['Config'].find_one({'type': 'nascan'})["config"]['Port_list']["value"]
            value = value + '|' + origin_value.split('|')[1]
        elif name == 'Masscan_Flag':
            name = 'Masscan'
            path = Mongo.coll['Config'].find_one({'type': 'nascan'})["config"]["Masscan"]["value"]
            if len(path.split('|')) == 3:
                path = path.split('|')[1] + "|" + path.split('|')[2]
            else:
                path = path.split('|')[1]
            if value == '':
                value = '1|' + path
            else:
                value = '0|' + path
        result = Mongo.coll['Config'].update({"type": conftype}, {'$set': {'config.' + name + '.value': value}})
        if result:
            rsp = 'success'
    return rsp

　　

先判断是更新哪一个配置。

根据name来判断是哪个配置，就从数据库去取对应的值，然后把提交过来的value加上去更新。

均为更新插件的，不细分析。

在https://sec.ly.com/xunfeng/getlist 查询出最新插件，然后与数据库比较。

查看是否本地有安装。

阅读了view.py 里的每个方法具体都是干嘛的，对巡风扫描器整体有一个大概了解。
