从commons-fileupload源码看⽂件上传绕waf
之前hvv的时候遇到个⽂件上传，有waf没绕过去就想着从⽂件上传解析流程看看有什么可利⽤的地⽅，
于是有了这篇⽂章。
那次主要是⽂件名的地⽅绕不过去，尝试了挺多⽅法就不⼀⼀说了。
⾸先搭建了⼀个和⽬标类似的环境，使⽤commons-fileupload做⽂件上传。
⾸先在 formLists = fileUpload.parseRequest(request); 处打断点跟⼊⽂件上传解析流
程。
注意到下⾯肯定是以及解析完了，那么解析的地⽅肯定在箭头处。

如果之前有调试tomcat源码的话可以知道 Filter 是在 tomcat 服务器启动时通过 init 方法启动
的，服务器关闭时通过 destroy 方法销毁。中间通过执行 doFilter 方法进行进行过滤。

在参与BugBounty时，排⾏榜中有⼀些⼈分数很⾼，除了他很勤奋外，还有很好的⾃动化来发现资产中的漏洞，像h1这
种赏⾦平台竞争也很⼤，明显的漏洞⼏乎很少，要不资产独特，要不漏洞点很隐蔽，否则不容易发现,我在⼀开始接触
这个平台，因为xss最好上⼿，所以我花了很多时间在这上⾯，但是反射型xss很容易重复，因为其他⼈也很容易发现，
或者扫到，所以最开始那段时间，我把⽬光集中在Dom Xss上，并且制作了⾃动化来帮助我发现这种类型的漏洞，尽管
国内并不重视Xss，但是国外对于Xss的奖励还算可观，所以对于学习这个漏洞类型来说很有助⼒，因为有钱赚 (^-^)，

任意文件下载击溃跳板站点
这次的实战渗透过程，信息收集是很重要的一个阶段。尽可能收集目标网站或目标主机尽量多的信
息。信息收集的方式：
主动信息收集是通过直接访问网站主动获取信息，对IP开放的端口、CMS、中间件、敏感目
录、敏感文件、脚本类型、JS里的域名、操作系统扫描分析。
被动信息收集是基于公开的渠道，在不与目标系统直接交互的情况下获取信息，比如搜索引擎
获取网站的URI、获取IP绑定的域名、C段、域名whois信息、证书对应的其他资产做扩展信息收
集。
常用的几个小技巧：
1）利用windows和linux区分大小写的区别，在访问的时候尝试把路径部分改成大写，

使用静态代码检测微服务越权、未授权访问漏洞
作者：xsser
背景
现在的互联网很多都是来自阿里那一套，公司的整体的应用的架构都
是微服务，在微服务下基于 spring boot 之类的搭建了 一套开发体
系。在历史的发展下，微服务一般发展成这样的架构
安全做为一个属性，需要深入契合这个框架。为什么要讲微服务呢？
因为有统一的框架，可以通过静态代码去一些事情。外购的系统，不
能接入到微服务里的，我们没办法拿到源代码，也自然无法做静态代
码的事情。
难以解决的安全问题
当今在越来越完善的 SDLC 安全建设之下，很多安全问题已经逐步变
少，例如 SQLI、RCE 等，企业的安全建设在研发安全方面已经逐步完

SSRF基础知识
ssrf出现最根本的原因，就是服务端使⽤了⽹络函数，⽽⼀般编程语⾔⽹络函数底层调⽤的都是 curl (当然，这个
要看具体的函数代码以及底层逻辑)，curl⼜⽀持很多协议，所以ssrf就可以使⽤这些协议。

实战攻防演习之
紫队视角下的实战攻防演习组织

前 言
网络实战攻防演习，是新形势下关键信息系统网络
安全保护工作的重要组成部分。演习通常是以实际运
行的信息系统为保护目标，通过有监督的攻防对抗，
最大限度地模拟真实的网络攻击，以此来检验信息系
统的实际安全性和运维保障的实际有效性。
2016年以来，在国家监管机构的有力推动下，网
络实战攻防演习日益得到重视，演习范围越来越广，
演习周期越来越长，演习规模越来越大。国家有关部
门组织的全国性网络实战攻防演习从2016年仅有几家
参演单位，到2019年已扩展到上百家参演单位；同时
各省、各市、各行业的监管机构，也都在积极地筹备
