Name of API: Settings API Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=678695
Brief purpose of API: API to configure device settings General Use Cases: None
Inherent threats:
- Access sensitive configuration data (wifi passwords etc)
- Change settings which might cost user money (data settings, roaming etc)
- Safety implications (airplane mode? If you believe a plane can be brought down by a mobile phone...)
Threat severity: High
Regular web content (unauthenticated)
Use cases for unauthenticated code: Read/change non-sensitive settings Authorization model for normal content: None Authorization model for installed content: Implicit read access to limited settings. Write access OS mediated. Potential mitigations: Only non-sensitive settings will be exposed to regular apps.
Trusted (authenticated by publisher)
Use cases for authenticated code: Modify a specific setting - e.g. e-book app modifies brightness in response to lighting conditions Authorization model: Implicit Potential mitigations: Access to a subset of lower risk settings
Certified (vouched for by trusted 3rd party)
Use cases for certified code: replacement settings manager app Authorization model: Implicit access to all settings Potential mitigations: None
