The COPPA error page in the Accounts setup dialog in Mozilla Firefox OS before 2.2 embeds content from an external web server URL into the System process, which allows man-in-the-middle attackers to bypass intended access restrictions by spoofing that server.

Security readout for executives and security teams

CVE-2015-5961 affects Mozilla Firefox OS before 2.2. A COPPA error page in account setup loaded external web content inside the privileged System process, creating a path for a network man-in-the-middle to bypass intended restrictions by spoofing that server. Exposure appears limited to legacy Mozilla Firefox OS deployments before version 2.2 and specifically the Accounts setup dialog COPPA error page path. Modern environments are unlikely to run Firefox OS, but embedded, lab, or archived devices should be checked. Treat this as a legacy-platform risk, not an enterprise-wide emergency. Prioritize if your organization still owns Firefox OS devices, inherited mobile test labs, or embedded deployments using old Firefox OS images. Mitigation focus: Identify any Mozilla Firefox OS devices or images below version 2.2.; Upgrade affected Firefox OS deployments to 2.2 or later where supported.; Review Mozilla MFSA-2015-75 and vendor guidance for fixed builds..
