Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
StoreKit in Apple iOS before 6.1 does not properly handle the disabling of JavaScript within the preferences configuration of Mobile Safari, which allows remote attackers to bypass intended access restrictions and execute JavaScript code via a web site with a Smart App Banner.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

StoreKit in Apple iOS before 6.1 fails to respect the user's JavaScript disable preference in Mobile Safari settings. When a user disables JavaScript for security reasons, Smart App Banners (used for app promotion links) can still execute JavaScript code, bypassing the user's intended security restriction.

MitigationUpgrade affected iOS devices to iOS 6.1 or later. For legacy systems that cannot upgrade, users should be aware that Smart App Banners may execute JavaScript regardless of Safari JavaScript preferences.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check iOS version
    Navigate to Settings > General > About > Version, or check via iTunes or MDM tools
    Affected if Version is 6.0, 6.0.1, 6.0.2, or any version earlier than 6.1
  2. Verify JavaScript is disabled in Safari
    Go to Settings > Safari and confirm the 'Enable JavaScript' toggle is turned OFF
    Affected if JavaScript is disabled in Safari settings (this is the user preference that the vulnerability bypasses)
  3. Confirm exposure to Smart App Banners
    Visit websites in Mobile Safari that use Smart App Banners (websites with <meta name="apple-itunes-app" content="app-id=..."> in their HTML)
    Affected if You visit sites with Smart App Banners while running an affected iOS version AND JavaScript is disabled

You are affected if you run iOS 6.0 through 6.0.2, have disabled JavaScript in Safari settings, and visit websites displaying Smart App Banners, because the banners will execute JavaScript despite your disabled preference.

Interim mitigation

Upgrade affected iOS devices to iOS 6.1 or later. For legacy systems that cannot upgrade, users should be aware that Smart App Banners may execute JavaScript regardless of Safari JavaScript preferences.
