# [!] Problem

There are currently some problems:
1. If yakit proxy is not used, uploading of malicious plug-ins will fail;
2. After the webshell is uploaded, if you want to make a post request, an error will be reported, as shown below:

![](https://raw.githubusercontent.com/W01fh4cker/blog_image/main/image-20240308230546869.png)

But this problem can also be solved. Just get the X-TC-CSRF-Token corresponding to the session id through a 403 error. For example, I uploaded the webshell ofbehinder3.0 and connected:

3. There are still some details that need to be improved, such as the removal of malicious plugins, etc.If you have relevant coding skills, you can make pull requests.

# Vulnerability recurrence environment construction

Use docker to pull the vulnerable image and start it:

```shell
sudo docker pull jetbrains/teamcity-server:2023.11.3
sudo docker run -it -d --name teamcity -u root -p 8111:8111 jetbrains/teamcity-server:2023.11.3

Then make basic settings:
