A vulnerability has been identified in SCALANCE M875 (All versions). An authenticated remote attacker with access to the web interface (443/tcp), could potentially read and download arbitrary files from the device's file system. Successful exploitation requires that the attacker has network access to the web interface. The attacker must be authenticated as administrative user to exploit the security vulnerability. At the time of advisory publication no public exploitation of this security vulnerability was known.
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 exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
