Path traversal vulnerability exists in Redmine DMSF Plugin versions prior to 3.1.4. If this vulnerability is exploited, a logged-in user may obtain or delete arbitrary files on the server (within the privilege of the Redmine process).
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.
