CVE-2022-39911 is a vulnerability identified in Samsung Pass, a biometric authentication and password management application integrated into Samsung Mobile devices. The vulnerability is categorized under CWE-703, which pertains to improper check or handling of exceptional conditions. This flaw exists in versions of Samsung Pass prior to 4.0.06.1, allowing an attacker to potentially bypass security controls and gain unauthorized access to Samsung Pass. The vulnerability arises because the application does not correctly handle exceptional or error conditions, which can be exploited to circumvent authentication mechanisms or trigger unintended behavior. Although specific technical exploitation details are not provided, the nature of CWE-703 suggests that the application might fail to properly validate or respond to error states, leading to unauthorized access. Samsung Pass stores sensitive user credentials, biometric data, and other authentication tokens, making unauthorized access a significant security concern. There are no known exploits in the wild reported as of the publication date, and no official patches or updates have been linked in the provided information, although Samsung has reserved the CVE since September 2022 and published the vulnerability in December 2022. The vulnerability 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.

The potential impact of this vulnerability on European organizations is notable, particularly for enterprises and individuals relying on Samsung devices for secure authentication and password management. Unauthorized access to Samsung Pass could lead to compromise of stored credentials, biometric data, and authentication tokens, which in turn could facilitate lateral movement within corporate networks, unauthorized access to corporate applications, and data breaches. This risk is heightened in sectors with stringent data protection requirements such as finance, healthcare, and government agencies. The compromise of biometric data also raises privacy concerns under GDPR regulations. Although no active exploitation is reported, the vulnerability's presence in widely used devices means that targeted attacks or phishing campaigns could leverage this flaw to gain initial access or escalate privileges. The impact on availability is limited, but confidentiality and integrity of sensitive authentication data are at risk. Organizations using Samsung devices as part of their security infrastructure or BYOD policies should consider this vulnerability seriously.

To mitigate this vulnerability, European organizations should take the following specific actions: 1) Ensure all Samsung devices are updated to Samsung Pass version 4.0.06.1 or later as soon as the patch becomes available, verifying updates through official Samsung channels. 2) Implement device management policies that restrict the use of vulnerable Samsung Pass versions, especially on corporate devices. 3) Enforce multi-factor authentication (MFA) for critical applications and services to reduce reliance on Samsung Pass alone for authentication. 4) Monitor device logs and authentication attempts for unusual activity that could indicate exploitation attempts. 5) Educate users on the risks of using outdated software and encourage prompt installation of security updates. 6) Consider alternative secure password management solutions or biometric authentication methods if patching is delayed. 7) For high-security environments, temporarily disable Samsung Pass or restrict its use until the vulnerability is remediated. 8) Collaborate with Samsung support and security teams to receive timely updates and advisories.
