CVE-2017-2389

Name of the Vulnerable Software and Affected Versions iOS versions prior to 10.3 Safari versions prior to 10.1

Description The issue involves the Safari component and allows remote attackers to spoof an HTTP authentication sheet or cause a denial of service via a crafted web site. It is related to insufficient access control in the Safari browser and iOS operating system, which can be exploited by a remote attacker to bypass HTTP authentication or cause a denial of service using a specially crafted website.

Recommendations For iOS versions prior to 10.3, update to version 10.3 or later to resolve the issue. For Safari versions prior to 10.1, update to version 10.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the Safari component until a patch is available.
