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

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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 8 Mar 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 26 Oct 2026.

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 or the CVSS exploit maturity 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 fixes for this vulnerability in iOS 17.4 and iPadOS 17.4. Users and administrators should apply these updates to remediate the issue. No additional mitigation steps are required beyond installing the official patches.

Description

CVE-2024-23220 is a medium severity vulnerability affecting Apple iOS and iPadOS where an app may be able to fingerprint the user. The issue was addressed by Apple with improved handling of caches and is fixed in iOS 17.4 and iPadOS 17.4. The vulnerability does not involve direct confidentiality compromise but may allow an app to uniquely identify or track a user. Apple has released official patches for this issue as part of their iOS 17.4 and iPadOS 17.4 updates.

Impact

An app exploiting this vulnerability may be able to fingerprint the user, potentially enabling tracking or profiling. There is no indication of direct data disclosure, privilege escalation, or system compromise. The impact is limited to user privacy and integrity of user identification. No known exploits are reported in the wild at this time.

Summary

CVE-2024-23220 is a vulnerability in Apple iOS and iPadOS that could allow an application to fingerprint the user. The root cause relates to cache handling that could be exploited to gather identifying information about the user. Apple addressed this vulnerability by improving cache handling mechanisms. The fix is included in iOS 17.4 and iPadOS 17.4 releases. This vulnerability has a CVSS score of 4.0 (medium severity) with an attack vector limited to local access (AV:L), low complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impacts integrity but not confidentiality or availability.
