CVE-2022-38982 is a critical security vulnerability identified in Huawei's HarmonyOS version 2.0, specifically within the fingerprint authentication module. The vulnerability stems from a service logic error, categorized under CWE-287 (Improper Authentication). This flaw allows an attacker to bypass the phone's lock screen without requiring any privileges or user interaction, effectively cracking the device's lock. The vulnerability has a CVSS 3.1 base score of 9.8, indicating a critical severity level, with attack vector being network-based (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact affects confidentiality, integrity, and availability (all rated high), meaning an attacker can gain unauthorized access to sensitive data, potentially manipulate system integrity, and disrupt device availability. Although no known exploits have been reported in the wild, the vulnerability's nature and ease of exploitation make it a significant threat. The absence of a patch link suggests that remediation may still be pending or not publicly disclosed at the time of this report. Given the fingerprint module's role in device security, exploitation could lead to full device compromise, unauthorized data access, and potential lateral movement within connected networks or ecosystems relying on HarmonyOS devices.

For European organizations, the exploitation of CVE-2022-38982 poses a substantial risk, especially for enterprises and government bodies using Huawei HarmonyOS devices. Compromise of device locks can lead to unauthorized access to corporate emails, confidential documents, and secure applications, undermining data confidentiality and integrity. This could facilitate espionage, data theft, or sabotage. The critical nature of the vulnerability means that attackers can bypass biometric security without user interaction or privileges, increasing the risk of widespread exploitation. Additionally, compromised devices could serve as entry points for further attacks against corporate networks, potentially affecting operational continuity and availability of services. The threat is particularly acute for sectors handling sensitive personal data or critical infrastructure, where device security is paramount for compliance with GDPR and other regulatory frameworks. The lack of known exploits in the wild provides a window for proactive mitigation, but organizations should treat this vulnerability with urgency given its severity and potential impact.

European organizations should implement a multi-layered mitigation strategy beyond generic patching advice. First, they should inventory all Huawei HarmonyOS 2.0 devices within their environment and restrict their use for accessing sensitive systems until a vendor patch is available. Employ device management solutions to enforce strict access controls and monitor device behavior for anomalies indicative of exploitation attempts. Where possible, disable fingerprint authentication and switch to alternative authentication methods such as strong PINs or passwords temporarily. Network segmentation should be enforced to isolate vulnerable devices from critical infrastructure. Organizations should also engage with Huawei for timely updates and patches and apply them immediately upon release. Additionally, implement endpoint detection and response (EDR) tools capable of detecting suspicious activities related to authentication bypass attempts. User awareness campaigns should inform employees about the risks and encourage reporting of unusual device behavior. Finally, consider deploying mobile threat defense (MTD) solutions that can provide real-time protection against exploitation attempts targeting mobile OS vulnerabilities.
