WebAPI/Security/NetworkInformation
Name of API: Network Information API Sec Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=677166 https://wiki.mozilla.org/WebAPI/NetworkAPI
Brief purpose of API: General Use Cases: Read current bandwidth estimate or ask if connection is metered
Listen for connection change events
Inherent threats: Privacy (de-anonymize users based on connection change events?)
Threat severity:Low
Regular web content (unauthenticated)
Use cases for unauthenticated code: Read current bandwidth estimate or ask if connection is metered Authorization model for normal content: Read current bandwidth estimate or ask if connection is metered Authorization model for installed content: Potential mitigations: Maybe fuzz the exact time of the network change event in a similar manner to idle API.
Trusted (authenticated by publisher)
Use cases for authenticated code:As above Use cases for trusted code: Potential mitigations:
Certified (vouched for by trusted 3rd party)
Use cases for certified code: As above Authorization model: Potential mitigations:
