Many of those items can be used for DoS against the user, basically changing the settings to something strange, so that the user would not have a properly working access. The following items could be interesting for an attacker to modify. We will later on elaborate new cases what this subscriber profile contains and what it implies if an attacker gets hold of the subscriber profile.
