01

What, why and how

This issue was addressed through improved state management. This issue is fixed in iOS 16.7.9 and iPadOS 16.7.9, iOS 17.6 and iPadOS 17.6, macOS Ventura 13.6.8. An attacker may be able to view sensitive user information.

What

This issue was addressed through improved state management. This issue is fixed in iOS 16.7.9 and iPadOS 16.7.9, iOS 17.6 and iPadOS 17.6, macOS Ventura 13.6.8. An attacker may be able to view sensitive user information.

Why

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Improper Access Control → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Network
Privileges required
None: unauthenticated exploitation is possible
User interaction
None
Attack complexity
Low: no specialised conditions are recorded
Security boundary
Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-284 ↗

CWE-284: Improper Access Control. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.INoneIntegrity impact: No direct loss is represented by this metric.ANoneAvailability impact: No direct loss is represented by this metric.
Post-exploitation / living off the land
No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.

NCSC-NL · Dutch · NCSC-2024-0320Kwetsbaarheden verholpen in Apple MacOS

Een kwaadwillende kan de kwetsbaarheden misbruiken om een beveiligingsmaatregel te omzeilen, zichzelf verhoogde rechten toe te kennen, toegang te krijgen tot gevoelige gegevens, willekeurige code uit te voeren, mogelijk met kernel-rechten of een Denial-of-Service te veroorzaken. Voor succesvol misbruik moet de kwaadwillende het slachtoffer misleiden een malafide app te installeren en draaien, of een malafide link te volgen. Voor het uitvoeren van willekeurige code met kernel-rechten moet de kwaadwillende reeds beschikken over verhoogde rechten op het kwetsbare systeem.

NCSC-NL · Dutch · NCSC-2024-0319Kwetsbaarheden verholpen in Apple iOS en iPadOS

Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot een Denial-of-Service, toegang tot systeemgegevens of toegang tot gevoelige gegevens. Om toegang te krijgen tot gevoelige gegevens, moet de kwaadwillende fysieke toegang hebben tot het kwetsbare systeem. Om een Denial-of-Service te veroorzaken, of systeemgegevens te bemachtigen moet de kwaadwillende het slachtoffer misleiden een malafide app te installeren en draaien.
