CVE-2024-27856 is classified as a high-severity vulnerability with a CVSS score of 7.8. This vulnerability allows unexpected app termination or arbitrary code execution when processing a malicious file. The impact of this vulnerability is significant, affecting a range of Apple products, including Safari and various operating systems such as macOS, iPadOS, and iPhone OS.
The vulnerability was disclosed as a result of improved checks in the affected software. It has been patched in the latest versions, including macOS Sonoma 14.5, iOS 16.7.8, iPadOS 16.7.8, Safari 17.5, watchOS 10.5, tvOS 17.5, and visionOS 1.2. Organizations using these products should be aware of the potential risks and prioritize applying the necessary updates.
Risk to organizations includes possible unauthorized access and system instability. Given the severity of this vulnerability, organizations should prioritize patching immediately to mitigate potential threats. The absence of known exploits or public proof of concept further highlights the urgency for defenders to take action.
Organizations using Apple products, particularly those in sectors relying on iOS and macOS for critical operations, should assess their exposure to this vulnerability. Regular software updates and security assessments are essential in maintaining a robust security posture.
Vulnerability Details
The issue was addressed with improved checks, specifically in the handling of files by the affected components. This vulnerability is classified under CWE-94, which pertains to code injection vulnerabilities. The specific products affected include Safari, iPadOS, iPhone OS, macOS, tvOS, visionOS, and watchOS.
The CVSS 3.1 vector string for this vulnerability is CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating a local attack vector with low complexity, no privileges required, and user interaction necessary. The impacts on confidentiality, integrity, and availability are all rated as high.
Technical Analysis
The root cause of this vulnerability stems from improper checks when processing files, which could lead to arbitrary code execution. The attack vector is local, meaning that an attacker would need to have access to the target system to exploit this vulnerability. The complexity of the attack is low, and no special privileges are required, making it accessible for attackers with basic capabilities.
User interaction is required to trigger the vulnerability, further complicating the attack but not diminishing its risk. The vulnerability poses a high impact on confidentiality, integrity, and availability since successful exploitation could lead to unauthorized access and control over the affected application.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses significant risks to organizations, particularly those heavily reliant on Apple's ecosystem for their operations. The potential for unauthorized access and the resulting system instability can lead to data breaches or service disruptions. Organizations should consider this vulnerability's potential blast radius, especially if the affected products are integrated into critical business processes.
Given the CVSS score of 7.8, organizations should address this vulnerability in their priority patch cycle. The absence of known exploitation at the time of disclosure does not eliminate the risk; proactive measures should be taken to ensure software is updated and vulnerabilities are remediated.
