Remediation

Vendor Solution

1. Uninstall MASmobile Classic Services - These services are installed and configured manually in IIS within a virtual directory. To uninstall, unpublish the services in IIS and remove the service files. All versions (v1.7, 1.8, and 1.9) were discontinued. 2. Remove the MASmobile Classic app from Android and iOS devices. All versions (v1.x.x) were discontinued and no longer available in the app stores (Play and AppStore). 3. Contact MAS to arrange the installation of MASterMind EX Services (v6.46 or later). These services do not run under IIS and must be configured in coordination with the customer. 4. Install MASmobile app from Play or AppStore (v2.x.x). This is not an upgrade to MASmobile Classic; it is a different app.
