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
A logic issue was addressed with improved file handling. This issue is fixed in iOS 17.7.1 and iPadOS 17.7.1, iOS 18.1 and iPadOS 18.1, tvOS 18.1, visionOS 2.1. Restoring a maliciously crafted backup file may lead to modification of protected system files.

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

A logic flaw in Apple's backup restoration process allows a maliciously crafted backup file to bypass file handling restrictions and overwrite protected system files. This could enable privilege escalation or system compromise by restoring a specially crafted backup.

MitigationApply the vendor-supplied patches (iOS 17.7.1+/iOS 18.1+/tvOS 18.1+/visionOS 2.1+) and avoid restoring backups from untrusted or unknown sources.

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. Identify your device's iOS or iPadOS version
    On the device, go to Settings > General > About to view the iOS/iPadOS version number
    Affected if The version is below 17.7.1, or is 18.0 through any version lower than 18.1
  2. Identify your Apple TV's tvOS version
    On Apple TV, go to Settings > General > About to view the tvOS version number
    Affected if The version is below 18.1
  3. Identify your Apple Vision Pro's visionOS version
    On the device, go to Settings > General > About to view the visionOS version number
    Affected if The version is below 2.1
  4. Determine if backup restoration from external sources is permitted
    Verify if the device allows restoring from locally sourced or unencrypted backups from sources other than iCloud
    Affected if The device permits restoring backups from untrusted or unknown sources and the OS version falls within the affected ranges

A device is affected if it runs iOS/iPadOS < 17.7.1 or >= 18.0 but < 18.1, tvOS < 18.1, or visionOS < 2.1, and if backup restoration from untrusted sources is enabled.

Interim mitigation

Apply the vendor-supplied patches (iOS 17.7.1+/iOS 18.1+/tvOS 18.1+/visionOS 2.1+) and avoid restoring backups from untrusted or unknown sources.

Recommended fix High confidence

iOS 17.7.1/iPadOS 17.7.1, iOS 18.1/iPadOS 18.1, tvOS 18.1, visionOS 2.1

  1. Back up your device data before performing the update
  2. Go to Settings > General > Software Update on your iPhone, iPad, Apple TV, or Apple Vision Pro
  3. Download and install iOS 17.7.1 or iOS 18.1 (depending on your current iOS version) for iPhone
  4. Download and install iPadOS 17.7.1 or iPadOS 18.1 for iPad
  5. Download and install tvOS 18.1 for Apple TV
  6. Download and install visionOS 2.1 for Apple Vision Pro
  7. After update, verify the system is running the fixed version in Settings > General > About
Caveat Ensure device compatibility with iOS 18.1 before upgrading; iOS 18 requires iPhone XS or later
