Brief purpose of API: Make and receive phone calls
- WebAPI:https://wiki.mozilla.org/WebAPI/WebTelephony
- B2G Meta telephony bughttps://bugzilla.mozilla.org/show_bug.cgi?id=699235
- Web Telephony meta bug:https://bugzilla.mozilla.org/show_bug.cgi?id=674726
General Use Cases: None
Inherent threats:
- Place calls to high cost numbers,
- Route calls through high cost network,
- Direct calls through MITM network (spying).
- Possibly with audio API, record phone calls, record touch tone signals (account numbers?).
- In addition, there is a high likelihood that this API will need to be controlled for legal reasons.
Threat severity: high to critical, confidential information disclosure and direct financial risk
Regular web content (unauthenticated)
Use cases for unauthenticated code: click on a phone number in an email or browser to dial
- Authorization model for uninstalled web content: explicit (web activities)
- Authorization model for installed web content: explicit (web activities)
- Potential mitigations: When user clicks on a phone number, app triggers a web activity to initiate the call. User interaction required to trigger.
Trusted (authenticated by publisher)
Use cases for authenticated code:
- Fun dialers (eg. rotary dialer)
Authorization model: explicit (web activities)
Certified (vouched for by trusted 3rd party)
Use cases for certified code:
- Handler for telephony web activities
- Replacement dialer
- Voice conference software (e.g. connect Voip with a mobile call)?
- Mediate incoming calls (accept/reject/merge)
- Query transceiver state
Authorization model: implicit Potential mitigations: none
