CVE-2024-27833 is a high-severity vulnerability affecting multiple Apple products, including Safari, iOS, iPadOS, tvOS, and visionOS. The vulnerability stems from an integer overflow that can be exploited through maliciously crafted web content, leading to arbitrary code execution. The CVSS score for this vulnerability is 8.8, reflecting its serious nature and the potential impact on users.
Given the widespread use of affected products, organizations must assess their exposure and prioritize patching. This vulnerability is particularly critical as it requires user interaction, making it essential for users to avoid untrusted sources while patches are being applied.
The vulnerability was published on June 10, 2024, and it is imperative for users to update to the latest versions of Safari (17.5), iOS (16.7.8 and 17.5), iPadOS (16.7.8 and 17.5), tvOS (17.5), and visionOS (1.2) to mitigate the risk.
Risk to organizations includes unauthorized access and potential data breaches due to exploitation. Therefore, organizations should prioritize patching immediately.
Vulnerability Details
The vulnerability is classified as CWE-190, indicating an integer overflow. This vulnerability allows attackers to exploit the flaw via network access. User interaction is required to trigger the overflow, and the attack vector is categorized as low complexity.
The CVSS score of 8.8 highlights the high severity of the vulnerability, with impacts on confidentiality, integrity, and availability all rated high.
Affected versions include Safari versions prior to 17.5, iOS 16.7.8, iPadOS 16.7.8, iOS 17.5, iPadOS 17.5, tvOS 17.5, and visionOS 1.2.
Technical Analysis
The root cause of CVE-2024-27833 is an integer overflow, which occurs when a calculation exceeds the maximum limit of the integer data type. This flaw can be triggered when processing specially crafted web content.
The attack vector is network-based, requiring an attacker to craft malicious web content that targets the vulnerability. The complexity of the attack is low, as it does not necessitate elevated privileges, and user interaction is required to access the malicious content.
The attack can result in high impacts across confidentiality, integrity, and availability, making it a significant concern for users of affected systems.
Risk & Impact Analysis
Organizations that utilize Apple products must recognize the real-world risks associated with this vulnerability. The integer overflow could allow attackers to execute arbitrary code, potentially leading to unauthorized access and data compromise.
With a widespread deployment of affected systems, the blast radius could be significant. Attackers may exploit this vulnerability to gain control over devices, affecting the integrity of sensitive information.
Organizations should address this vulnerability in priority patch cycles. Given its high CVSS score and potential impact, immediate action is necessary to mitigate risks.
