Unrestricted file upload (RCE) in express-cart module before 1.1.7 allows a privileged user to gain access in the hosting machine.
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.
The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
