Technical Analysis

CVE-2022-39108 is a high-severity vulnerability identified in multiple Unisoc (Shanghai) Technologies Co., Ltd. System on Chips (SoCs), specifically models SC9863A, SC9832E, SC7731E, T610, T310, T606, T760, T618, T612, T616, T770, T820, and S8000. These SoCs are integrated into various Android devices running Android 10, 11, and 12. The vulnerability arises from a missing authorization check within the Music service component of the affected devices. This missing permission verification allows an attacker with limited privileges (low-level privileges) to elevate their privileges within the Music service without requiring additional execution privileges or user interaction. The vulnerability is classified under CWE-862 (Missing Authorization), indicating that the system fails to verify whether the user or process has the necessary permissions before performing sensitive operations. The CVSS 3.1 base score of 7.8 reflects a high severity, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits have been reported in the wild, the vulnerability's nature means that an attacker with local access could exploit it to gain unauthorized control or access to sensitive data within the Music service, potentially leading to broader system compromise depending on the integration of this service with other system components.

Potential Impact

For European organizations, the impact of CVE-2022-39108 can be significant, especially for those relying on devices powered by Unisoc SoCs in their operational environments. The vulnerability allows privilege escalation locally, which could be exploited by malicious insiders or malware that has gained limited access to the device. This could lead to unauthorized access to sensitive media or user data managed by the Music service, potentially exposing confidential information or enabling further lateral movement within the device. Given the high confidentiality, integrity, and availability impacts, exploitation could disrupt business operations, compromise user privacy, and damage organizational reputation. In sectors such as telecommunications, manufacturing, or public services where such devices might be used for communication or operational tasks, the risk is amplified. Additionally, the lack of user interaction requirement means automated or stealthy exploitation is feasible once local access is achieved, increasing the threat level.

Mitigation Recommendations

To mitigate CVE-2022-39108, European organizations should implement a multi-layered approach beyond generic patching advice: 1) Identify and inventory all devices using the affected Unisoc SoCs and Android versions (10, 11, 12) within the organization to understand exposure. 2) Engage with device vendors and Unisoc to obtain and deploy firmware or software updates that address the missing authorization check as soon as they become available. 3) Restrict local access to devices by enforcing strict physical security controls and endpoint protection measures to prevent unauthorized users from gaining low-level privileges. 4) Employ mobile device management (MDM) solutions to monitor and control installed applications and services, limiting the ability of malicious apps to exploit the Music service. 5) Implement behavioral monitoring to detect unusual privilege escalation attempts or anomalous activity related to the Music service. 6) Educate users about the risks of installing untrusted applications or granting unnecessary permissions that could facilitate exploitation. 7) Where feasible, isolate critical devices from untrusted networks or users to reduce the attack surface. These targeted steps will help reduce the risk of exploitation and limit potential damage.
