CVE-2024-40770
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 · uneditedA permissions issue was addressed with additional restrictions. This issue is fixed in macOS Sequoia 15. A non-privileged user may be able to modify restricted network settings.
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 · moderate confidenceA permission bypass vulnerability in macOS Sequoia 15 allowed unprivileged users to modify restricted network settings due to insufficient authorization checks. The fix involved adding additional restrictions to enforce proper permission validation before allowing network configuration changes.

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 installed macOS versionRun 'sw_vers -productVersion' in Terminal or go to Apple menu > About This Mac to see the exact macOS version numberAffected if The version is below 15.0 (any version of macOS before Sequoia)
-
Verify current user privilegesRun 'whoami' and 'id' in Terminal to see if the current user is an administrator or standard userAffected if A standard (non-admin) user account exists on the system who could potentially exploit this flaw
-
Test restricted network settings accessAs a standard (non-admin) user, attempt to open System Settings > Network and try to modify advanced settings like DNS servers, proxy configuration, or custom network configurationsAffected if A standard user can access and modify restricted network configuration options without being prompted for admin credentials
-
Check for recent network configuration changesRun 'sudo system_profiler SPNetworkDataType' or check system logs with 'log show --predicate 'eventMessage contains "network"' --last 24h' for any unauthorized network configuration modificationsAffected if Network settings were changed by an unprivileged user or at unexpected times
A system is affected if it runs macOS version below 15.0 and allows standard (non-admin) users to modify restricted network settings without authorization prompts.
