Pydio Cells before 1.5.0 fails to neutralize '../' elements, allowing an attacker with minimum privilege to Upload files to, and Delete files/folders from, an unprivileged directory, leading to Privilege escalation.
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.
