CVE-2022-32880 is a medium-severity vulnerability affecting Apple macOS systems prior to the Monterey 12.5 update. The vulnerability arises from insufficient enforcement of security boundaries that allow an application to access user-sensitive data without proper authorization. Specifically, the issue was mitigated by enabling the hardened runtime feature, which enforces stricter runtime protections to prevent unauthorized data access by applications. The vulnerability is categorized under CWE-284, indicating an authorization bypass or insufficient access control flaw. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N), the vulnerability can be exploited remotely over the network without privileges, but requires user interaction (such as running a malicious app). The impact is high on confidentiality since sensitive user data can be exposed, but there is no impact on integrity or availability. No known exploits are currently reported in the wild, and the affected versions are unspecified but presumably all macOS versions before 12.5 that do not have hardened runtime enabled. This vulnerability highlights the risk of apps bypassing macOS's security model to access sensitive information, which could include personal files, credentials, or other private data stored on the device.

For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive corporate and personal data on macOS devices. Organizations with employees using macOS systems could face data leakage if malicious applications exploit this flaw, potentially exposing intellectual property, personal identifiable information (PII), or confidential communications. Given the medium severity and requirement for user interaction, targeted phishing or social engineering campaigns could be used to trick users into running malicious apps. This could be particularly impactful in sectors with high data sensitivity such as finance, healthcare, and government institutions. Additionally, exposure of sensitive data could lead to regulatory non-compliance under GDPR, resulting in legal and financial penalties. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time.

European organizations should prioritize updating all macOS devices to version 12.5 or later, where the hardened runtime is enabled by default, effectively mitigating this vulnerability. IT administrators should enforce strict application whitelisting policies and restrict installation of untrusted or unsigned applications to reduce the risk of malicious app execution. User awareness training should emphasize the dangers of running unknown applications and recognizing phishing attempts that may deliver such apps. Endpoint protection solutions with behavioral analysis can help detect suspicious app activities attempting unauthorized data access. Additionally, organizations should audit macOS security configurations to ensure hardened runtime and other macOS security features are enabled and properly configured. Regular vulnerability scanning and patch management processes should be enforced to promptly address similar vulnerabilities in the future.
