1Panel is an open source Linux server operation and maintenance management panel. In version 1.4.3, an arbitrary file write vulnerability could lead to direct control of the server. In the api/v1/file.go file, there is a function called SaveContentthat,It recieves JSON data sent by users in the form of a POST request. And the lack of parameter filtering allows for arbitrary file write operations. Version 1.5.0 contains a patch for this issue.
