Impact
Per: https://ics-cert.us-cert.gov/advisories/ICSA-14-238-02 "WIS may allow access to local resources (files and internal resources) via unsafe parsing of XML external entities. By using specially crafted XML files, an attacker can cause these products to send the contents of local remote resources to the attacker’s server or cause a denial of service of the system. This vulnerability is not exploitable remotely and cannot be exploited without user interaction. The exploit is only triggered when a local user runs the vulnerable application and loads the malformed XML files."
