Mozilla Firefox before 3.0.10 processes a 3xx HTTP CONNECT response before a successful SSL handshake, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying this CONNECT response to specify a 302 redirect to an arbitrary https web site.

Security readout for executives and security teams

This is an old Mozilla Firefox issue affecting versions before 3.0.10. A network attacker positioned between the browser and destination could interfere with an HTTPS proxy connection and cause script to run as if it belonged to an HTTPS site. Modern exposure should be limited to obsolete Firefox installations. Exposure is most likely in unmanaged legacy systems, archived virtual machines, kiosks, or embedded desktops still running Firefox before 3.0.10. No other affected products are identified in the supplied bundle. Treat this as a legacy exposure cleanup item, not an emergency, unless obsolete Firefox is still present in sensitive environments. Prioritize confirmation through asset inventory. Mitigation focus: Upgrade or remove Mozilla Firefox versions earlier than 3.0.10.; Retire systems unable to run a supported modern browser.; Check vendor or distribution guidance for legacy package remediation details..
