Detailsinfo

A vulnerability classified as critical has been found in donknap dpanel up to 1.9.1. This affects some unknown functionality of the file app/common/http/controller/attach.go. The manipulation of the argument path with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on integrity, and availability. The summary by CVE is:

DPanel is an open source server management panel written in Go. Prior to 1.9.2, DPanel has an arbitrary file deletion vulnerability in the /api/common/attach/delete interface. Authenticated users can delete arbitrary files on the server via path traversal. When a user logs into the administrative backend, this interface can be used to delete files. The vulnerability lies in the Delete function within the app/common/http/controller/attach.go file. The path parameter submitted by the user is directly passed to storage.Local{}.GetSaveRealPath and subsequently to os.Remove without proper sanitization or checking for path traversal characters (../). And the helper function in common/service/storage/local.go uses filepath.Join, which resolves ../ but does not enforce a chroot/jail. This vulnerability is fixed in 1.9.2.
