Technical Analysis

CVE-2022-39892 is a vulnerability identified in Samsung Pass, a biometric and password management application integrated into Samsung Mobile devices. The flaw is categorized under CWE-287, which pertains to improper authentication mechanisms. Specifically, versions of Samsung Pass prior to 4.0.05.1 contain an improper access control issue related to the 'keep open' feature. This feature is designed to maintain an authenticated session for user convenience. However, due to insufficient authentication checks, an attacker can exploit this feature to gain unauthenticated access to Samsung Pass functionalities. The vulnerability does not require prior privileges (PR:N) but does require local access (AV:L), meaning the attacker must have physical or local device access. User interaction is required (UI:R), indicating that some form of user action, such as triggering the 'keep open' feature, is necessary for exploitation. The vulnerability impacts confidentiality (C:L) but not integrity or availability. The scope is changed (S:C), implying that the vulnerability affects components beyond the initially vulnerable module, potentially impacting other system components or data. The CVSS score is 3.6, indicating a low severity level. No known exploits have been reported in the wild, and no patches are explicitly linked in the provided data, though the issue is resolved in versions 4.0.05.1 and later. The vulnerability primarily affects Samsung Mobile devices running vulnerable versions of Samsung Pass, which is widely used in Samsung smartphones, especially in regions with high Samsung market penetration.

Potential Impact

For European organizations, the impact of CVE-2022-39892 is primarily on the confidentiality of stored credentials and biometric data managed by Samsung Pass on employee devices. If exploited, attackers with local access could bypass authentication controls and access sensitive authentication data, potentially leading to unauthorized access to corporate resources if such credentials are reused or synchronized. However, the requirement for local access and user interaction limits remote exploitation risks. The vulnerability does not affect data integrity or device availability, reducing the risk of broader operational disruption. Nonetheless, in environments where Samsung devices are used to access sensitive systems, this vulnerability could facilitate lateral movement or privilege escalation if combined with other attack vectors. The impact is more pronounced in sectors with high reliance on mobile device authentication, such as finance, government, and critical infrastructure within Europe.

Mitigation Recommendations

1. Upgrade Samsung Pass to version 4.0.05.1 or later on all Samsung devices to ensure the vulnerability is patched. 2. Enforce strict device access controls, including strong lock screen authentication (PIN, password, biometrics) to prevent unauthorized local access. 3. Disable or restrict the use of the 'keep open' feature in Samsung Pass through device management policies or user education to minimize exposure. 4. Implement Mobile Device Management (MDM) solutions to monitor and control application versions and configurations on corporate devices. 5. Educate users about the risks of leaving devices unattended and the importance of not enabling features that maintain persistent authentication without supervision. 6. Conduct regular audits of device security posture, focusing on authentication mechanisms and application versions. 7. For highly sensitive environments, consider restricting the use of Samsung Pass or similar password managers on corporate devices until patched versions are confirmed deployed.
