CVE-2024-42219 is a high-severity vulnerability affecting 1Password 8 for macOS. This vulnerability allows local attackers to exfiltrate vault items because XPC inter-process communication validation is insufficient. The CVSS score for this vulnerability is 7.8, indicating a significant risk to organizations utilizing this software. Given its nature and potential impact, organizations should prioritize patching immediately.
The exploitation status for this vulnerability is currently reported as not being actively exploited; however, the potential for local exploitation remains a concern. Attackers leveraging this vulnerability could access sensitive vault items, which underscores the urgency for organizations to address this issue promptly.
1Password users are urged to update their software to version 8.10.36 or later to mitigate this risk. Organizations should ensure their patch management processes are equipped to handle such security updates swiftly and efficiently.
Failure to remediate this vulnerability may expose organizations to unauthorized access to confidential data, potentially leading to data breaches and compliance issues.
Given the critical nature of this vulnerability, it is essential for security teams to stay informed about updates and to implement robust security practices to safeguard against potential exploitation.
Vulnerability Details
The vulnerability described in CVE-2024-42219 is characterized as a local privilege escalation flaw due to insufficient validation in XPC inter-process communication within 1Password 8 prior to version 8.10.36. The CVSS score of 7.8 categorizes it as high severity, indicating that the potential impact on confidentiality, integrity, and availability is significant.
The vulnerability affects all versions of 1Password 8 before version 8.10.36 for macOS. The specific CWE classification is CWE-1289, which relates to issues in inter-process communication.
Technical Analysis
The root cause of this vulnerability stems from inadequate validation in the XPC inter-process communication mechanism, which fails to sufficiently authenticate requests between processes. As a result, local attackers can exploit this flaw to gain access to sensitive vault items.
The attack vector is classified as local, requiring physical or local access to the affected system. The attack complexity is low, meaning that an attacker can exploit the vulnerability without sophisticated skills or resources.
Privileges required for exploitation are low, as the attacker does not need elevated permissions to execute the attack. User interaction is not required, which further increases the risk.
The impact on confidentiality, integrity, and availability is high, as the vulnerability could allow attackers to exfiltrate sensitive information, modify data, or disrupt service availability.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive vault items, which may lead to data breaches and legal complications. The potential blast radius is significant, particularly for organizations that rely heavily on 1Password for managing sensitive information.
Organizations should assess their risk posture in light of this vulnerability, particularly in environments where local access may be achievable by malicious actors. The urgency to address this vulnerability is high, given the potential for significant implications on data security.
