An access issue was addressed with improved access restrictions across multiple Apple products. This vulnerability allows a maliciously crafted webpage to potentially fingerprint users. The issue has been fixed in Safari 17.3, iOS 16.7.5 and iPadOS 16.7.5, iOS 17.3 and iPadOS 17.3, macOS Sonoma 14.3, tvOS 17.3, and watchOS 10.3. The potential for user fingerprinting poses a risk to user privacy and security.
The severity of this vulnerability is classified as medium with a CVSS score of 6.5. This means that while the risk is present, it is not immediately critical. Organizations should prioritize patching immediately to mitigate the impact of this vulnerability.
The vulnerability is publicly acknowledged, and Apple has released patches to address it. It is crucial for users to update their systems to the latest versions to ensure protection against this vulnerability, as it could potentially lead to unauthorized tracking of users through malicious webpages.
Risk to organizations includes exposure to privacy violations and potential loss of sensitive user information. This reinforces the need for all users of affected Apple products to take immediate action in updating their systems.
Given the nature of this vulnerability and its implications, organizations should address it in their priority patch cycle. Regular updates and vigilance are essential to maintaining security in an increasingly complex threat landscape.
Vulnerability Details
CVE-2024-23206 is an access issue that was addressed with improved access restrictions. The vulnerability allows a maliciously crafted webpage to fingerprint users. It is classified under CWE-200, indicating information exposure. This vulnerability has a CVSS score of 6.5, which denotes a medium severity.
Affected products include Safari, iOS, iPadOS, macOS, tvOS, and watchOS. The vulnerability was published on January 23, 2024, and has since been addressed in the latest versions of these products.
Technical Analysis
The root cause of this vulnerability lies in insufficient access restrictions implemented in the affected software. Attackers may leverage this vulnerability through crafted web pages that require user interaction to trigger the issue. The attack vector is network-based, and the complexity is low, requiring no privileges to exploit.
The user interaction required indicates that a user must visit the malicious webpage for the fingerprinting to occur. The impact on confidentiality is high as user information could be exposed, while integrity and availability impacts are negligible.
Risk & Impact Analysis
The real-world risk associated with CVE-2024-23206 is significant, particularly for organizations relying on Apple products for sensitive transactions or data handling. The potential for user fingerprinting can lead to unwanted tracking and privacy breaches.
This vulnerability is critical for organizations as it opens avenues for more severe attacks, including targeted phishing attempts based on user behavior and profile. Given the CVSS score of 6.5, organizations should schedule remediation in their patch cycles to ensure that systems are protected against this vulnerability.

Affected Versions
All versions of Safari prior to 17.3, iOS 16.0 to 16.7.5, iPadOS 16.0 to 16.7.5, iOS 17.0 to 17.3, iPadOS 17.0 to 17.3, macOS prior to Sonoma 14.3, tvOS prior to 17.3, and watchOS prior to 10.3 are affected by this vulnerability.
Mitigation & Remediation
Organizations are encouraged to apply the latest patches provided by Apple to their devices. For Safari, the latest version is 17.3; for iOS, it is 16.7.5 or 17.3; iPadOS 16.7.5 or 17.3; macOS Sonoma 14.3; tvOS 17.3; and watchOS 10.3.
If patching is not feasible, organizations should implement security controls such as web filtering to prevent access to potentially malicious sites and conduct user training to make them aware of the risks.
Additionally, organizations should monitor network traffic for unusual behavior that may indicate exploitation attempts.
Continuous security testing can help identify vulnerabilities in the environment.
Detection Guidance
Organizations should implement logging to capture web requests and responses, particularly focusing on any unusual or unexpected behavior while accessing web pages. Monitoring for signatures that may indicate attempts to fingerprint users should also be prioritized.
Anomalous user behaviors should be analyzed to identify potential exploitation attempts. Security teams should also be alert for any reports regarding unauthorized data collection.
AppSecure Threat Intelligence Insight
CVE-2024-23206 highlights the ongoing challenges in web security and the importance of robust access control mechanisms. As attackers seek ways to exploit vulnerabilities, organizations must remain proactive in their security practices.
This vulnerability serves as a reminder that even widely used applications like Safari can have critical access issues. Organizations should continually assess their security postures and ensure that they are applying updates promptly.
To mitigate future risks, organizations should consider implementing a comprehensive vulnerability management program that incorporates regular assessments and user training.
Organizations should also invest in penetration testing to identify and remediate vulnerabilities before they can be exploited.
Lastly, organizations should consider adopting a red teaming approach to simulate attacks and enhance their security strategies.
