Mozilla Firefox before 31.0 and Thunderbird before 31.0 do not properly implement the sandbox attribute of the IFRAME element, which allows remote attackers to bypass intended restrictions on same-origin content via a crafted web site in conjunction with a redirect.

Security readout for executives and security teams

This is an old Mozilla browser and mail-client flaw. Firefox and Thunderbird before 31.0 mishandled the HTML iframe sandbox attribute, allowing a malicious site plus redirect to bypass restrictions meant to isolate same-origin content. Exposure is most likely in environments still running Firefox or Thunderbird versions earlier than 31.0, including legacy desktops, kiosks, embedded workflows, or old Linux distributions. Treat this as legacy exposure cleanup, not an emergency from the provided evidence. Prioritize if old Mozilla clients remain in internet-facing user workflows. Mitigation focus: Upgrade Firefox and Thunderbird to 31.0 or later.; Check Mozilla and OS vendor advisories for supported fixed packages.; Remove or isolate unsupported legacy browser and mail-client installations..
