CVE-2024-44258
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 · uneditedThis issue was addressed with improved handling of symlinks. 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 confidenceA symlink handling vulnerability in iOS, iPadOS, tvOS, and visionOS backup restoration allows a maliciously crafted backup file to modify protected system files by exploiting symlink resolution during the restore process. The attacker creates a backup containing a symlink that points to a protected system file, and when the backup is restored, the symlink is followed, bypassing file protection.

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 or iPadOS versionGo to Settings > General > About > Version and note the version number. Compare it to the affected ranges: < 17.7.1, or >= 18.0 and < 18.1Affected if The version falls within < 17.7.1 or >= 18.0 and < 18.1
-
Check tvOS versionGo to Settings > General > About > Version on the Apple TV and note the version number. Compare it to the affected range: < 18.1Affected if The version is earlier than 18.1
-
Check visionOS versionGo to Settings > General > About > Version on the Vision Pro and note the version number. Compare it to the affected range: < 2.1Affected if The version is earlier than 2.1
-
Identify backup restore activityReview whether any backup files from untrusted or unknown sources have been restored to the device. Check backup file origins and timestamps in your records or the device backup settings.Affected if A backup from an untrusted or unknown source has been restored to the device
The device is affected if it runs an affected iOS/iPadOS version (< 17.7.1 or >= 18.0 to < 18.1), tvOS version (< 18.1), or visionOS version (< 2.1) AND a backup from an untrusted source has been restored, allowing symlink manipulation of protected system files.
