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
iCloud Data Access in Apple iOS before 8.1 does not verify X.509 certificates from TLS servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

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

iCloud Data Access in Apple iOS before 8.1 fails to verify X.509 certificates during TLS server connections. This allows man-in-the-middle attackers to intercept traffic by presenting crafted certificates, enabling server spoofing and unauthorized access to sensitive data.

MitigationUpgrade iOS devices to version 8.1 or later to implement proper X.509 certificate validation. Organizations should identify and update all managed iOS devices running earlier versions.

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 the iOS version installed on the device
    Go to Settings > General > About and look at the 'Version' field. This displays the exact iOS version number (for example, 8.0, 8.0.1, 8.0.2).
    Affected if The version number is 8.0.2 or lower (any version up to and including 8.0.2).
  2. Confirm iCloud is enabled on the device
    Navigate to Settings > iCloud. If iCloud is turned off, the iCloud Data Access feature is not being used.
    Affected if iCloud is turned ON and the device is signed into an iCloud account.
  3. Check if iCloud Drive or iCloud Data features are active
    In Settings > iCloud, verify if 'iCloud Drive' or other data sync features are enabled. Also check Settings > Photos to see if iCloud Photo Library is enabled.
    Affected if Any iCloud data synchronization feature (Drive, Photos, Documents, Backup) is turned on.

The device is affected if it runs iOS version 8.0.2 or earlier AND has iCloud data sync features enabled, making it vulnerable to MITM attacks on iCloud connections.

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 data
Upgrade available Upgrade to a release after 8.0.2
Interim mitigation

Upgrade iOS devices to version 8.1 or later to implement proper X.509 certificate validation. Organizations should identify and update all managed iOS devices running earlier versions.
