CVE-2024-23263: Processing maliciously crafted web content may prevent Content Security Policy from being enforced in Apple Safari
CVE-2024-23263 is a logic vulnerability in Apple Safari and related WebKit components that could allow processing of maliciously crafted web content to prevent enforcement of the Content Security Policy (CSP). This issue was addressed by Apple through improved validation and state management. The vulnerability affects multiple Apple platforms including Safari 17. 4, iOS 16. 7. 6 and later, iPadOS 16. 7. 6 and later, macOS Sonoma 14. 4, tvOS 17. 4, visionOS 1.
AI Analysis
Technical Summary
CVE-2024-23263 is a high-severity logic vulnerability in Apple Safari's WebKit engine where processing maliciously crafted web content may prevent the Content Security Policy from being enforced. The issue stems from improper state management and validation in WebKit. Apple addressed this vulnerability by improving validation and state management in Safari 17.4 and corresponding OS releases including iOS, iPadOS, macOS, tvOS, visionOS, and watchOS. The vulnerability has a CVSS 3.1 base score of 8.1 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N), indicating network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality and integrity but no impact on availability. Apple’s official security updates provide patches for this issue, mitigating the risk of CSP bypass via malicious web content.
Potential Impact
If exploited, this vulnerability could allow an attacker to bypass Content Security Policy enforcement in Safari and related WebKit-based browsers on affected Apple platforms. This could lead to increased risk of cross-site scripting (XSS) or data injection attacks, potentially compromising user confidentiality and integrity of web content. The CVSS score of 8.1 reflects the high impact on confidentiality and integrity. However, there are no reports of active exploitation in the wild at this time.
Mitigation Recommendations
Apple has released official patches for this vulnerability in Safari 17.4, iOS 16.7.6 and iPadOS 16.7.6, iOS 17.4 and iPadOS 17.4, macOS Sonoma 14.4, tvOS 17.4, visionOS 1.1, and watchOS 10.4. Users and administrators should update affected Apple devices and software to these versions or later to mitigate this vulnerability. No additional action is required beyond applying these official updates.
