CVE-2024-44192 is a vulnerability identified in Apple Safari that allows an attacker to cause an unexpected process crash by delivering maliciously crafted web content. The root cause is related to insufficient input validation and resource management, categorized under CWE-400 (Uncontrolled Resource Consumption). When Safari processes specially crafted web content, it may exhaust resources or trigger conditions that lead to a denial-of-service (DoS) state by crashing the browser process. This affects multiple Apple platforms including Safari 18 on iOS 18, iPadOS 18, macOS Sequoia 15, tvOS 18, visionOS 2, and watchOS 11. The vulnerability requires no privileges or prior authentication but does require user interaction, such as visiting a malicious webpage. The CVSS v3.1 base score is 6.5, reflecting a medium severity level, with attack vector network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), no impact on confidentiality or integrity (C:N/I:N), and high impact on availability (A:H). Apple has addressed the issue with improved input validation and resource checks in the latest software updates. No public exploits have been reported to date, but the vulnerability could be leveraged to disrupt user activities or automated systems relying on Safari, especially in environments where browser stability is critical.

The primary impact of CVE-2024-44192 is denial-of-service through unexpected browser crashes, which can disrupt normal user activities such as web browsing, online transactions, and access to web-based applications. For organizations, this can translate into productivity loss, interruptions in customer-facing services, and potential cascading effects if Safari is used in automated workflows or kiosk environments. While the vulnerability does not compromise confidentiality or integrity, repeated crashes could be exploited to degrade service availability or as part of a broader attack strategy to distract or disrupt operations. Enterprises relying heavily on Apple devices and Safari for critical business functions may face operational risks until patches are applied. Additionally, environments with limited ability to update devices promptly may remain exposed to potential exploitation attempts.

To mitigate CVE-2024-44192, organizations and users should promptly update Safari and all affected Apple operating systems to the latest versions: Safari 18, iOS 18, iPadOS 18, macOS Sequoia 15, tvOS 18, visionOS 2, and watchOS 11. Beyond patching, organizations should implement network-level protections such as web filtering and intrusion prevention systems to block access to known malicious websites. Employing endpoint protection solutions that monitor browser behavior can help detect abnormal crashes or exploitation attempts. User education is important to reduce the risk of visiting untrusted or suspicious websites. For managed environments, consider restricting Safari usage to trusted sites or deploying alternative browsers with different rendering engines as a temporary workaround. Monitoring logs for repeated browser crashes can provide early indicators of attempted exploitation. Finally, maintain an inventory of Apple devices and ensure timely patch management processes are in place to reduce exposure windows.
