An out-of-bounds read issue was addressed with improved input validation. This issue is fixed in Security Update 2022-005 Catalina, macOS Monterey 12.5. An app may be able to gain elevated privileges.
AI Analysis
Technical Summary
CVE-2022-32842 is a high-severity vulnerability affecting Apple macOS systems, specifically addressed in Security Update 2022-005 Catalina and macOS Monterey 12.5. The root cause is an out-of-bounds read issue, classified under CWE-125, which occurs due to insufficient input validation. This flaw allows a malicious application to read memory outside the intended buffer boundaries, potentially leading to elevated privileges. The vulnerability can be exploited locally (AV:L) with low attack complexity (AC:L), without requiring prior privileges (PR:N), but does require user interaction (UI:R). Successful exploitation can compromise confidentiality, integrity, and availability of the affected system, as the attacker may gain high-level privileges, enabling them to execute arbitrary code, access sensitive data, or disrupt system operations. Although no known exploits are currently reported in the wild, the CVSS score of 7.8 indicates a significant risk, warranting prompt attention. The vulnerability affects unspecified versions of macOS, but the patches are available in recent security updates, emphasizing the importance of timely patching.
Potential Impact
For European organizations, this vulnerability poses a considerable threat, especially those relying on Apple macOS devices within their IT infrastructure. Elevated privileges gained through this flaw could allow attackers to bypass security controls, access confidential corporate data, or deploy malware, potentially leading to data breaches, intellectual property theft, or operational disruptions. Sectors such as finance, healthcare, government, and critical infrastructure, which often use macOS for secure environments, may face heightened risks. Additionally, organizations with remote or hybrid workforces using macOS devices are vulnerable to exploitation via social engineering or malicious applications requiring user interaction. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future attacks, making proactive mitigation essential.
Mitigation Recommendations
European organizations should implement the following specific measures: 1) Immediately apply the Security Update 2022-005 Catalina and macOS Monterey 12.5 patches to all macOS devices to remediate the vulnerability. 2) Enforce strict application control policies using Apple’s built-in tools like Gatekeeper and System Integrity Protection (SIP) to limit execution of untrusted or unsigned applications. 3) Educate users about the risks of installing or interacting with unknown applications to reduce the chance of exploitation via user interaction. 4) Employ endpoint detection and response (EDR) solutions tailored for macOS to monitor for suspicious privilege escalation attempts or anomalous behavior. 5) Regularly audit and restrict user privileges to the minimum necessary, reducing the impact of potential privilege escalation. 6) Maintain an up-to-date inventory of macOS devices and ensure compliance with patch management policies. 7) Consider network segmentation to isolate critical macOS systems and limit lateral movement in case of compromise.
