CVE-2017-2359 Apple CVE debrief

Who should care

Organizations and users still running Safari 10.0.2 or earlier, especially on legacy Apple systems, should care because the issue can mislead users into trusting a deceptive webpage.

Technical summary

The vulnerability is a browser UI spoofing problem in Safari. The NVD record shows a network-exploitable issue with user interaction required (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N). The primary impact is integrity: a crafted webpage may visually impersonate the browser’s address bar, which can support phishing or other user-deception attacks. The vulnerable range is Safari before 10.0.3, with the NVD CPE criteria ending at 10.0.2.

Defensive priority

Recommended defensive actions

• Update Safari to version 10.0.3 or later on affected Apple systems.
• Verify legacy or long-lived devices are not pinned to Safari 10.0.2 or earlier.
• Use browser and user-training controls to reduce susceptibility to address-bar spoofing and phishing.
• Confirm Apple security advisories such as HT207484 are reflected in your patch management records.
