CVE-2014-4363
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 · uneditedSafari in Apple iOS before 8 does not properly restrict the autofilling of passwords in forms, which allows remote attackers to obtain sensitive information via (1) an http web site, (2) an https web site with an unacceptable X.509 certificate, or (3) an IFRAME element.
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 confidenceSafari in iOS before 8 improperly auto-fills passwords in insecure contexts: unencrypted HTTP pages, HTTPS sites with invalid certificates (indicating MITM), and within IFRAME elements. This allows remote attackers to extract credentials via malicious pages or man-in-the-middle intercepts.

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 checksWork through these to decide whether this CVE applies to you.
-
Check iOS versionGo to Settings > General > About and look at the Version number. For iPhone, this is found on the device itself.Affected if Version is 7.0 through 7.1.2 (iOS 7.0-7.1.2 includes Safari 7.0-7.0.5 which is vulnerable)
-
Confirm Safari password autofill is enabledGo to Settings > Safari > Passwords & Autofill and check if 'Autofill Passwords' toggle is turned ON.Affected if Autofill Passwords is enabled, making the device susceptible to credential extraction via the vulnerable auto-fill behavior
-
Check for iOS version history or MDM inventoryQuery your mobile device management (MDM) system or check device enrollment profiles for the iOS version reported by each managed device.Affected if Any managed device reports iOS version 7.0-7.1.2 as the current installed version
-
Identify devices that cannot be upgradedReview devices that are unable to receive iOS 8 or later updates, typically iPhone 4 and older devices.Affected if Devices are running iOS 7.x and are hardware-limited to iOS 7.x, meaning they cannot receive the fix via update
A device is affected if it runs iOS 7.0-7.1.2 (or Safari 6.0-6.1.5/7.0-7.0.5) and has Safari password autofill enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade all iOS devices to version 8 or later to receive the Safari fix. For devices that cannot upgrade, consider using alternative browsers or implementing MDM to restrict autofill behavior until devices can be replaced.
