CVE-2022-32845 is a critical vulnerability affecting Apple macOS and related operating systems including watchOS 8.7, iOS 15.6, and iPadOS 15.6. The vulnerability allows a malicious application to break out of its sandbox environment, which is a core security mechanism designed to isolate apps and restrict their access to system resources and user data. By exploiting this flaw, an attacker could execute arbitrary code with elevated privileges, potentially gaining full control over the affected device. The vulnerability is classified under CWE-693, which relates to protection mechanism failures, indicating that the sandbox escape results from insufficient enforcement of security boundaries. The CVSS v3.1 base score is 10.0, reflecting the highest severity due to the vulnerability's network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and a scope change (S:C) that affects confidentiality, integrity, and availability (all rated high). Apple addressed this issue by implementing improved checks in the affected operating systems, thereby preventing apps from bypassing sandbox restrictions. Although no known exploits have been reported in the wild as of the publication date, the critical nature of this vulnerability and its ease of exploitation make it a significant threat to all users of affected Apple platforms.

For European organizations, this vulnerability poses a severe risk, especially for those relying on Apple macOS and iOS devices within their IT infrastructure. The ability for an app to escape the sandbox can lead to unauthorized access to sensitive corporate data, compromise of user credentials, and potential deployment of malware or ransomware with elevated privileges. This could result in data breaches, operational disruption, and loss of intellectual property. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly at risk due to the sensitivity of their data and regulatory requirements under GDPR and other European data protection laws. The vulnerability's exploitation could also undermine endpoint security measures and complicate incident response efforts. Given the widespread use of Apple devices in European enterprises and among remote workers, the potential impact is broad and significant.

European organizations should prioritize immediate patching of all affected Apple devices by upgrading to macOS Monterey 12.5, iOS 15.6, iPadOS 15.6, and watchOS 8.7 or later versions where the vulnerability is fixed. Beyond patching, organizations should implement strict application control policies to limit the installation of untrusted or unsigned applications, reducing the risk of malicious apps exploiting this vulnerability. Employing Mobile Device Management (MDM) solutions can enforce compliance with patching and security policies across all Apple devices. Network segmentation should be used to isolate critical systems and limit lateral movement in case of compromise. Additionally, monitoring for unusual app behavior or privilege escalations through endpoint detection and response (EDR) tools can help detect exploitation attempts early. User education on the risks of installing unverified apps and maintaining strong authentication mechanisms further reduce exposure. Finally, organizations should review and update their incident response plans to address potential sandbox escape scenarios.
