Attack Vector: Network
Attack Complexity: Low
Privileges Required: None
User Interaction: None
Scope: Unchanged
Confidentiality: None
Integrity: None
Availability: Low

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 13 May 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Apple has released official patches addressing CVE-2024-27816 in iOS 17.5, iPadOS 17.5, and macOS Sonoma 14.5. Users and administrators should apply these updates promptly to remediate the vulnerability. Since the vendor advisory confirms the issue is fixed with improved checks, no additional mitigation steps are required beyond updating to the fixed OS versions.

Description

CVE-2024-27816 is a logic issue in Apple iOS, iPadOS, and macOS Sonoma that could allow an attacker to access user data due to insufficient checks. This vulnerability is addressed by improved validation and logic checks in the AppleMobileFileIntegrity component. Apple released patches for this issue in iOS 17.5, iPadOS 17.5, and macOS Sonoma 14.5 on May 13, 2024. The CVSS score is 5.3, indicating a medium severity level. There are no known exploits in the wild at this time. The vulnerability affects devices with Apple Neural Engine starting from iPhone XS and later, various iPad Pro models, iPad Air 3rd generation and later, iPad 8th generation and later, and iPad mini 5th generation and later.

Impact

An attacker exploiting this vulnerability may be able to access user data on affected Apple devices due to a logic issue in AppleMobileFileIntegrity. The impact is limited to data access without elevation of privileges or code execution. The CVSS score of 5.3 reflects a medium severity impact. There are no known exploits in the wild, reducing immediate risk. The vulnerability affects multiple Apple platforms including iOS, iPadOS, and macOS Sonoma.
