Security readout for executives and security teams
Plain-English summary
CVE-2023-42958 is an Apple macOS permissions flaw. Apple says an app may be able to gain elevated privileges, meaning a program running on a Mac could get more control than intended. Apple fixed the issue in macOS Ventura 13.4.
Executive priority
Treat as high priority for Mac fleets because it can raise an app's privileges. Patch management should focus first on unmanaged endpoints and systems used by privileged staff, developers, and administrators.
Technical view
The CVE describes a local privilege escalation in macOS caused by a permissions issue addressed with additional restrictions. CVSS 3.1 is 7.8, with local attack vector, low complexity, no privileges required, user interaction required, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is most likely on macOS Ventura systems that have not received the 13.4 fix. The source bundle does not specify exact vulnerable builds, hardware models, or whether other macOS branches were affected.
Exploitation context
No CISA KEV listing is provided, and the supplied sources do not state active exploitation. The issue requires local context and user interaction per CVSS, but successful exploitation could grant elevated privileges.
Researcher notes
Public detail is limited. The CVE names a permissions issue and Apple says additional restrictions fixed it, but no CWE, component, proof-of-concept, or exploit telemetry is provided in the bundle.
Mitigation direction
- Update affected macOS Ventura systems to version 13.4.
- Check Apple security guidance for applicability to your supported macOS versions.
- Use device management to verify Ventura endpoints received the fixed release.
- Prioritize shared, developer, and high-privilege user workstations.
Validation and detection
- Inventory macOS Ventura devices and record exact OS versions.
- Confirm Ventura systems report macOS 13.4 or a later Apple-fixed state.
- Review endpoint management compliance for lagging or unmanaged Macs.
- Check security tools for unexpected privilege escalation alerts on Macs.
