CVE-2024-44309 is a medium-severity vulnerability impacting multiple Apple products, including Safari, iOS, and macOS. This vulnerability allows attackers to exploit cookie management issues, leading to potential cross-site scripting (XSS) attacks. With a CVSS score of 6.3, this vulnerability is classified as medium, indicating a significant risk to users if left unpatched.
The vulnerability was published on November 20, 2024. Apple has addressed this issue in several updates, including Safari 18.1.1, iOS 17.7.2, iPadOS 17.7.2, and macOS Sequoia 15.1.1. Users are urged to update their devices to these versions to mitigate the associated risks.
Risk to organizations includes potential unauthorized access to sensitive data through XSS attacks, particularly on Intel-based Mac systems. Apple has acknowledged reports of active exploitation of this vulnerability, which heightens the urgency for organizations to implement the necessary patches.
Given the potential impact and the active exploitation reports, organizations should prioritize patching immediately. It is crucial to ensure that all affected systems are updated to prevent malicious actors from leveraging this vulnerability.
Vulnerability Details
The official CVE description states that a cookie management issue was addressed with improved state management. Processing maliciously crafted web content may lead to a cross-site scripting attack. Vulnerable versions include Safari prior to 18.1.1, iOS prior to 17.7.2, and other Apple operating systems as listed in the CVE details.
The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L, indicating that exploitation requires user interaction and has a low attack complexity. The vulnerability has a confidentiality, integrity, and availability impact rated as low.
The affected products include various configurations of Apple products and Debian Linux, emphasizing the widespread nature of this vulnerability. The CWE classification is CWE-79, which denotes improper neutralization of input during web page generation (commonly known as XSS).
Technical Analysis
The root cause of CVE-2024-44309 stems from inadequate cookie management within the affected products. This mismanagement allows attackers to inject malicious scripts into web pages viewed by users. The attack vector primarily involves network access, where an attacker could deliver the crafted web content to unsuspecting users.
Once delivered, the attack complexity is low, as it does not require any special privileges to exploit the vulnerability. However, it does necessitate user interaction, meaning that users must visit a malicious webpage or click on a malicious link for the attack to succeed.
The impacts of this vulnerability are classified as low across confidentiality, integrity, and availability, indicating that while exploitation is possible, the actual damage may vary depending on the context of the attack. However, the potential for unauthorized data access remains a significant concern.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2024-44309 is considerable, especially in environments where users interact with untrusted web content. Given the nature of cross-site scripting attacks, the blast radius could extend to any user interacting with the affected applications, leading to data theft or unauthorized access.
Organizations must recognize that the exploitation of this vulnerability could lead to significant reputational damage and financial loss, particularly if sensitive user data is compromised. The urgency assessment indicates that with active exploitation reported and the availability of public exploit reports, the risk level is elevated.
Given the CVSS score of 6.3 and its classification as medium severity, organizations should address this vulnerability in their priority patch cycle. Patching is critical to maintaining the security posture of the organization and protecting user data.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | Yes |
Ransomware Use | No |
Affected Versions
All versions prior to vendor patch are affected, specifically:
• Safari versions before 18.1.1
• iOS versions before 17.7.2 and 18.1.1
• iPadOS versions before 17.7.2 and 18.1.1
• macOS prior to Sequoia 15.1.1
• visionOS versions before 2.1.1
Mitigation & Remediation
Organizations should apply the latest patches and updates provided by Apple, specifically upgrading to the fixed versions mentioned above. If immediate patching is not possible, users should consider implementing alternative security measures until patches can be applied.
Configuration hardening and network controls should be evaluated as additional preventive measures. Regular monitoring for unusual behavior in web applications can help detect potential attempts to exploit this vulnerability.
Organizations may also consider engaging in penetration testing to validate the effectiveness of their security measures.
Detection Guidance
Organizations should monitor server and application logs for indicators of exploitation attempts, such as unusual HTTP requests or unexpected script behaviors. Behavioral anomalies in user sessions may also indicate potential XSS attacks.
Network signatures can be implemented to detect malicious payloads indicative of XSS attempts. System changes that deviate from normal operations should be flagged for further analysis.
