The vulnerability was fixed with the release of iOS 9.2.1 on Tuesday, almost three years after it was first discovered and reported to Apple.</div>

Here's How the Vulnerability Worked</h3>

<div style="border: 0px; font-stretch: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
The vulnerability caused due to the way iOS handles <b style="border: 0px; font-family: inherit; font-size: inherit; font-stretch: inherit; font-style: inherit; font-variant: inherit; line-height: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">Cookie Stores </b>at <b style="border: 0px; font-family: inherit; font-size: inherit; font-stretch: inherit; font-style: inherit; font-variant: inherit; line-height: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">Captive Portals</b>, generally a login page that requires users to authenticate themselves before connecting to the free or paid public Wi-Fi hotspots when they are first joining.</div>
<div style="border: 0px; font-stretch: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">

So, when a user with a vulnerable iPhone or iPad connects to a captive-enabled network (<i style="border: 0px; font-family: inherit; font-size: inherit; font-stretch: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">sample page shown in the screenshot below</i>) – typically at coffee shops, hotels, and airports – a login window is displayed showing terms and conditions over a standard, unencrypted HTTP connection.</div>

Once accepted, the affected user is able to browse the Internet normally, but the embedded browser shares its unencrypted cookie store with the Safari browser.</div>
