CVE-2024-27820 is a high-severity vulnerability affecting multiple Apple products, including Safari, iOS, iPadOS, macOS, tvOS, visionOS, and watchOS. This vulnerability allows attackers to execute arbitrary code due to improper memory handling during the processing of web content. As a result, organizations using these systems are at risk of exploitation if they do not apply the necessary patches.
The CVSS score for this vulnerability is 8.8, indicating a high severity level that necessitates immediate attention from security teams. With a low attack complexity and no privileges required for exploitation, the urgency for patching is critical. If exploited, this vulnerability could lead to significant impacts on confidentiality, integrity, and availability.
Organizations should prioritize patching immediately, particularly for users of Safari, iOS, and related Apple products, as the risk of arbitrary code execution poses a significant threat.
As of now, there are no known public exploits or proof of concept (PoC) available for this vulnerability, but the potential for exploitation remains a concern, emphasizing the importance of timely remediation.
Vulnerability Details
The issue was addressed with improved memory handling in Safari 17.5, iOS 16.7.8, iPadOS 16.7.8, iOS 17.5, iPadOS 17.5, macOS Sonoma 14.5, tvOS 17.5, visionOS 1.2, and watchOS 10.5. The vulnerability is classified under CWE-119, concerning improper restriction of operations within the bounds of a memory buffer.
The high CVSS score of 8.8 indicates that successful exploitation could have a severe impact on the affected systems. The attack vector is network-based, with low complexity, no privileges required, and user interaction needed for successful exploitation.
Technical Analysis
The root cause of CVE-2024-27820 stems from improper memory handling when web content is processed. This flaw allows attackers to execute arbitrary code, potentially gaining unauthorized access to sensitive information or system controls.
The attack vector is through the network, with low complexity for the attacker to exploit. No privileges are necessary, but user interaction is required, meaning that users need to engage with malicious web content for exploitation to succeed.
The confidentiality, integrity, and availability impacts are all rated as high, confirming the severity of this vulnerability.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access and control over affected devices, leading to data breaches or further exploitation. The vulnerability is particularly concerning given that it affects widely used products in the Apple ecosystem, potentially impacting a significant number of users.
Organizations should assess the blast radius of this vulnerability, prioritizing patching for systems that are directly exposed to the internet or used in high-risk environments.
Given the high CVSS score and the potential for exploitation, organizations must act quickly to remediate this vulnerability. The urgency for patching is critical.
