The MicroSCADA Pro/X SYS600 product allows an authenticated user input to control or influence paths or file names that are used in filesystem operations. If exploited the vulnerability allows the attacker to access or modify system files or other files that are critical to the application.
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.
