Directory traversal vulnerability in Siemens WinCC (TIA Portal) 11 allows remote authenticated users to read HMI web-application source code and user-defined scripts via a crafted URL.
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.
