A CWE-22: Improper Limitation of a Pathname to a Restricted Directory vulnerability exists that could cause modification of an existing file by inserting at beginning of file or create a new file in the context of the Data Server potentially leading to remote code execution when an attacker sends a specially crafted message. Affected Product: Interactive Graphical SCADA System Data Server (V15.0.0.22020 and prior)
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.
