CVE-2022-2985 is a high-severity vulnerability identified in several Unisoc (Shanghai) Technologies Co., Ltd. chipsets, including SC9863A, SC9832E, SC7731E, and multiple others used in Android 10 and Android 11 devices. The vulnerability stems from a missing authorization check within the music service component of the affected systems. Specifically, this flaw allows an attacker with limited privileges (low-level privileges) to escalate their access rights to the contacts service without requiring additional execution privileges or user interaction. The vulnerability is classified under CWE-862, which refers to missing authorization, indicating that the system fails to properly verify whether a user or process has the necessary permissions before granting access to sensitive functionality or data. The CVSS v3.1 base score of 7.8 reflects a high severity, with the vector indicating that the attack requires local access (AV:L), low attack complexity (AC:L), privileges required are low (PR:L), no user interaction (UI:N), and the impact affects confidentiality, integrity, and availability at a high level (C:H/I:H/A:H). This means an attacker with local access can exploit the vulnerability relatively easily to gain unauthorized access and control over sensitive contact information and potentially disrupt system availability. Although no known exploits in the wild have been reported to date, the vulnerability poses a significant risk due to the sensitive nature of contact data and the broad impact on device security. The affected chipsets are commonly integrated into a range of Android devices, particularly in budget and mid-range smartphones, which may be widely used in various markets. The lack of a published patch link suggests that remediation may rely on vendor firmware updates or OEM patches, which may not be uniformly available or timely across all affected devices.

For European organizations, the impact of CVE-2022-2985 can be substantial, especially for enterprises relying on mobile devices powered by Unisoc chipsets running Android 10 or 11. The vulnerability allows local attackers, potentially malicious insiders or compromised applications, to escalate privileges and access sensitive contact information, which could lead to data breaches involving personal or corporate contacts. This can undermine confidentiality and privacy obligations under regulations such as GDPR. Furthermore, the ability to impact integrity and availability means attackers could manipulate contact data or disrupt services dependent on contact information, affecting business communications and operations. In sectors like finance, healthcare, and government, where secure contact management is critical, exploitation could facilitate further attacks such as social engineering, phishing, or lateral movement within networks. The lack of user interaction required for exploitation increases the risk of automated or stealthy attacks. Given the widespread use of Android devices in Europe, including in BYOD (Bring Your Own Device) scenarios, the vulnerability could affect a broad user base, increasing the attack surface for organizations.

To mitigate CVE-2022-2985 effectively, European organizations should: 1) Identify and inventory devices using affected Unisoc chipsets and running Android 10 or 11 to assess exposure. 2) Work closely with device manufacturers and vendors to obtain and deploy firmware or security patches as soon as they become available. 3) Implement strict application control policies to restrict installation of untrusted or unnecessary apps that could exploit local privilege escalation. 4) Enforce mobile device management (MDM) solutions to monitor device integrity, enforce security policies, and remotely manage or quarantine compromised devices. 5) Educate users about the risks of installing apps from unverified sources and the importance of device security hygiene. 6) Where possible, limit physical and local access to devices, as the vulnerability requires local access to exploit. 7) Monitor for unusual behavior indicative of privilege escalation or unauthorized access to contact data. 8) Consider network segmentation and data access controls to minimize the impact if a device is compromised. These steps go beyond generic advice by focusing on device-specific patch management, access control, and user awareness tailored to the nature of this vulnerability.
