CVE-2022-39883: CWE-285 Improper Authorization in Samsung Mobile Samsung Mobile Devices
Improper authorization vulnerability in StorageManagerService prior to SMR Nov-2022 Release 1 allows local attacker to call privileged API.
AI Analysis
Technical Summary
CVE-2022-39883 is an improper authorization vulnerability identified in Samsung Mobile Devices, specifically affecting the StorageManagerService component in Android versions Q (10), R (11), and S (12) prior to the November 2022 Security Maintenance Release (SMR). The vulnerability stems from insufficient authorization checks that allow a local attacker to invoke privileged APIs without proper permissions. This flaw is categorized under CWE-285 (Improper Authorization), indicating that the system fails to enforce correct access control policies. The vulnerability requires local access to the device, meaning an attacker must have some level of access to the device (e.g., via a malicious app or physical access) to exploit it. The CVSS v3.1 base score is 4.0 (medium severity), with vector AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L, indicating that the attack vector is local, with low attack complexity, no privileges required, no user interaction needed, and the impact is limited to availability (denial of service or disruption) without affecting confidentiality or integrity. Exploitation could allow an attacker to call privileged APIs that may disrupt storage management services, potentially causing denial of service or other availability issues. No known exploits in the wild have been reported to date, and no patches are explicitly linked in the provided information, though the issue is addressed in the November 2022 SMR. The vulnerability does not impact confidentiality or integrity directly but can affect the availability of storage-related services on affected Samsung devices.
Potential Impact
For European organizations, the impact of CVE-2022-39883 primarily concerns the availability of Samsung mobile devices used within corporate environments. Since the vulnerability allows local attackers to invoke privileged APIs improperly, it could lead to service disruptions or denial of service on affected devices. This may hinder employee productivity, especially in organizations relying heavily on Samsung mobile devices for communication, data access, or mobile workflows. Although the vulnerability does not compromise data confidentiality or integrity, the potential for availability disruption could affect critical business operations, particularly in sectors where mobile device uptime is essential (e.g., logistics, healthcare, finance). Additionally, if attackers leverage this vulnerability in conjunction with other exploits, it could form part of a multi-stage attack chain. However, the requirement for local access limits the attack surface, reducing the likelihood of widespread remote exploitation. The absence of known exploits in the wild further reduces immediate risk but does not eliminate the need for vigilance.
Mitigation Recommendations
To mitigate CVE-2022-39883 effectively, European organizations should: 1) Ensure all Samsung mobile devices are updated promptly with the November 2022 Security Maintenance Release or later, which addresses this vulnerability. 2) Implement strict mobile device management (MDM) policies to control app installations, preventing untrusted or malicious apps that could exploit local access vulnerabilities. 3) Enforce device access controls such as strong authentication (PIN, biometrics) to limit unauthorized local access. 4) Monitor device behavior for anomalies that may indicate exploitation attempts, including unusual API calls or service disruptions related to storage management. 5) Educate users about the risks of installing unverified applications and the importance of device security hygiene. 6) Consider deploying endpoint detection and response (EDR) solutions capable of monitoring mobile devices for suspicious activity. 7) Regularly audit device configurations and permissions to ensure no unnecessary privileges are granted to apps or users. These steps go beyond generic advice by focusing on controlling local access vectors and ensuring timely patch deployment within enterprise environments.
