The use of the weather bar in Outlook must be disabled


Overview

Finding ID Version Rule ID IA Controls Severity
V-41492 DTOO424 SV-54068r1_rule Medium
Description
The Weather Bar in Outlook displays weather conditions and forecast for a geographic location. By default, Outlook uses weather data provided by MSN Weather. The Weather Bar supports third-party weather data web services that follow a defined protocol to communicate with Outlook. As long as a third-party weather data service supports this protocol, users can choose that weather data service to provide weather data in the Weather Bar. Since the Weather Bar communicates to external, commercial weather sites, enabling it introduces the possibility of connections to malicious sites that could download malware into the environment.
