CVE-2023-41992 is a local privilege escalation vulnerability identified in Apple macOS and iOS operating systems. The flaw stems from insufficient validation checks within the system's privilege management components, allowing a local attacker with limited privileges to elevate their access rights to higher privilege levels, potentially root or system-level. This elevation can enable the attacker to execute arbitrary code with elevated permissions, access sensitive information, modify system configurations, or disrupt system availability. The vulnerability affects versions prior to macOS Monterey 12.7, iOS 16.7, iPadOS 16.7, and macOS Ventura 13.6, where Apple has implemented improved checks to mitigate this issue. The CVSS v3.1 base score is 7.8, reflecting high severity due to the combination of local attack vector, low attack complexity, required privileges, and no user interaction needed. Apple has acknowledged reports of active exploitation attempts targeting iOS versions before 16.7, indicating real-world risk. The vulnerability is classified under CWE-754, which relates to improper check for unusual or exceptional conditions, highlighting the root cause as inadequate validation in privilege escalation logic. While no detailed technical exploit code or patch links are provided, the mitigation involves updating to the fixed OS versions. This vulnerability is particularly critical because it can be exploited by any local user or malicious application that gains initial access, potentially leading to full system compromise.

For European organizations, the impact of CVE-2023-41992 can be significant, especially for those relying on Apple devices for business operations, including macOS workstations and iOS mobile devices. Successful exploitation could allow attackers to bypass security controls, access confidential corporate data, install persistent malware, or disrupt critical services. This is particularly concerning for sectors such as finance, healthcare, government, and critical infrastructure where data confidentiality and system integrity are paramount. The local nature of the attack means that initial access is required, but this could be achieved through other means such as phishing, malicious insiders, or compromised applications. Given the widespread use of Apple devices in European enterprises and among government employees, the vulnerability poses a tangible risk. Additionally, the potential for privilege escalation can facilitate lateral movement within networks, increasing the scope of compromise. The absence of required user interaction lowers the barrier for exploitation once local access is obtained. Therefore, the vulnerability could lead to significant operational disruption, data breaches, and reputational damage if exploited.

European organizations should prioritize patching all affected Apple devices by upgrading to macOS Monterey 12.7, iOS 16.7, iPadOS 16.7, or macOS Ventura 13.6 as applicable. Beyond patching, organizations should enforce strict local access controls, limiting user privileges to the minimum necessary and employing endpoint protection solutions capable of detecting suspicious privilege escalation attempts. Implementing application whitelisting and restricting the installation of untrusted software can reduce the risk of initial compromise. Regular auditing of user accounts and monitoring for unusual privilege escalations or system changes should be conducted. Network segmentation can help contain potential breaches originating from compromised Apple devices. Additionally, educating users about the risks of installing unverified applications and maintaining strong authentication mechanisms can reduce the likelihood of initial local access by attackers. Organizations should also keep abreast of any further advisories from Apple or security researchers regarding this vulnerability and related exploits.
