CVE-2022-39877: CWE-284 Improper Access Control in Samsung Mobile Group Sharing
Improper access control vulnerability in ProfileSharingAccount in Group Sharing prior to versions 13.0.6.15 in Android S(12), 13.0.6.14 in Android R(11) and below allows attackers to identify the device.
AI Analysis
Technical Summary
CVE-2022-39877 is an improper access control vulnerability identified in Samsung Mobile's Group Sharing feature, specifically within the ProfileSharingAccount component. This vulnerability affects Samsung devices running Android versions S (12) prior to 13.0.6.15 and R (11) and below prior to 13.0.6.14. The flaw allows an attacker to identify the device by exploiting insufficient access control mechanisms. Improper access control (CWE-284) means that the system does not adequately restrict access to resources or functions, enabling unauthorized entities to gain information or perform actions they should not be able to. In this case, the vulnerability does not allow for modification or disruption of data or services but leaks device identification information. The CVSS v3.1 base score is 4.0 (medium severity), with vector AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, indicating that the attack requires local access (adjacent network or physical proximity), low attack complexity, no privileges required, no user interaction, and impacts confidentiality only by leaking device identity information. There are no known exploits in the wild, and no patches are explicitly linked in the provided data, although Samsung has presumably addressed this in versions 13.0.6.15 (Android 12) and 13.0.6.14 (Android 11). The vulnerability's impact is limited to information disclosure without integrity or availability compromise, but it could be leveraged as part of a larger attack chain or for reconnaissance purposes.
Potential Impact
For European organizations, the primary impact of CVE-2022-39877 is the potential leakage of device identification information from Samsung mobile devices using the vulnerable Group Sharing feature. While this does not directly compromise sensitive data or disrupt services, it can aid attackers in profiling devices, enabling targeted phishing, social engineering, or further exploitation attempts. Organizations with a significant number of Samsung mobile users, especially in sectors with high security requirements such as finance, government, or critical infrastructure, may face increased risk of reconnaissance activities. The vulnerability requires local access, which limits remote exploitation but could be exploited in scenarios involving insider threats, compromised local networks, or physical proximity attacks (e.g., in public spaces or corporate environments). Given the widespread use of Samsung devices in Europe, the vulnerability could be leveraged to gather intelligence on devices within corporate environments, potentially facilitating more sophisticated attacks. However, the lack of known exploits and the medium severity rating suggest the immediate risk is moderate, but it should not be ignored in comprehensive mobile security strategies.
Mitigation Recommendations
To mitigate CVE-2022-39877 effectively, European organizations should: 1) Ensure all Samsung mobile devices are updated to the latest firmware versions, specifically versions 13.0.6.15 for Android 12 and 13.0.6.14 for Android 11 or later, as these versions address the vulnerability. 2) Implement strict network segmentation and access controls to limit local network exposure, reducing the risk of local attackers exploiting the vulnerability. 3) Enforce mobile device management (MDM) policies that restrict the use of Group Sharing features or monitor their usage, especially in sensitive environments. 4) Educate employees about the risks of local network attacks and encourage vigilance in public or unsecured Wi-Fi environments. 5) Conduct regular security audits and vulnerability assessments on mobile devices to detect outdated software or unauthorized access attempts. 6) Consider disabling Group Sharing functionality if it is not essential to business operations, thereby eliminating the attack surface related to this vulnerability. These steps go beyond generic advice by focusing on patch management, network controls, user education, and operational policies tailored to the specific nature of this vulnerability.
