Vulnerability details
TinyIce is a streaming server for audio and video. In versions 0.8.95 through 2.4.1, missing authentication on WebRTC ingest endpoint allows unauthenticated stream injection. Version 2.5.0 fixes the issue by requiring either HTTP Basic auth or a `?password=` query parameter,…
more
comparing the supplied password against the per-mount source password (or the `default_source_password` fallback) using bcrypt, hooking into the existing brute-force IP rate-limiter (5 failed attempts per IP within 15 minutes triggers a lockout), and rejecting requests for mounts in `disabled_mounts`. The same release also tightens an adjacent endpoint, `POST /admin/golive/chunk`, which previously required session authentication but did not verify the session user's per-mount access nor check the CSRF token.

Why these techniques?
Missing authentication on a public WebRTC ingest endpoint (CWE-306) directly enables remote exploitation of the streaming server without credentials.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
