CVE-2022-48618 Apple products Vulnerability And How To Stay Safe From It

CVE-2022-48618 is a significant cybersecurity vulnerability that was addressed by Apple with improved checks. This vulnerability was discovered in multiple Apple products, including macOS Ventura 13.1, watchOS 9.2, iOS 16.2, iPadOS 16.2, and tvOS 16.2. The issue lies in the ability of an attacker with arbitrary read and write capability to potentially bypass Pointer Authentication, a security feature in Apple’s operating systems.

The vulnerability was identified as having a high severity level, with a CVSS 3.x base score of 7.8, classified as HIGH. The CVSS vector for this vulnerability is CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating that it has a high impact on confidentiality, integrity, and availability.

The Common Weakness Enumeration (CWE) for CVE-2022-48618 is CWE-287, which corresponds to “Improper Authentication.” This classification suggests that the vulnerability arises from a flaw in the authentication mechanism of the affected software.

CVE-2022-48618 has been added to the Cybersecurity and Infrastructure Security Agency’s (CISA) Known Exploited Vulnerabilities Catalog, which is a list of known vulnerabilities that carry significant risk and have evidence of active exploitation. This addition underscores the importance of addressing this vulnerability promptly to protect against potential cyberattacks.

Impact of CVE-2022-48618

CVE-2022-48618 presents a significant security threat due to its ability to allow attackers with arbitrary read and write capability to bypass Pointer Authentication. This vulnerability is especially concerning because Pointer Authentication is a crucial security feature in Apple’s operating systems, designed to protect against certain types of exploits.

The impact of this vulnerability is considerable, as it could potentially lead to unauthorized access to sensitive information, execution of arbitrary code, or complete system compromise. Given the high CVSS 3.x base score of 7.8, the vulnerability poses a high risk to confidentiality, integrity, and availability of the affected systems.
