CFNetwork in Apple Mac OS X before 10.9 does not properly support Safari's deletion of session cookies in response to a reset operation, which makes it easier for remote web servers to track users via Set-Cookie HTTP headers.

Security readout for executives and security teams

This is a legacy Apple privacy weakness. On Mac OS X before 10.9, Safari’s reset operation did not reliably delete session cookies because of CFNetwork behavior. Remote websites could use HTTP Set-Cookie headers to continue tracking users after they expected cookies to be cleared. Exposure is mainly legacy Mac OS X systems older than 10.9 using Safari. Current enterprise exposure should be limited unless unmanaged, archived, kiosk, lab, or specialist systems still run pre-10.9 OS X. Treat as low urgency unless the organization still operates pre-10.9 Mac systems. It is primarily a privacy and user-tracking issue, but legacy unsupported endpoints may signal broader governance risk. Mitigation focus: Upgrade affected Mac OS X systems to 10.9 or later where possible.; Review Apple advisory APPLE-SA-2013-10-22-3 for vendor guidance.; Retire or isolate unsupported pre-10.9 Mac systems..
