CVE-2025-58283 is a permission control vulnerability identified in the Wi-Fi module of Huawei's HarmonyOS, specifically affecting versions 5.0.1 and 5.1.0. The root cause is improper enforcement of permissions and access controls (classified under CWE-264), which allows an attacker with local access and no prior privileges to exploit the flaw, provided user interaction occurs. The vulnerability impacts the confidentiality of services related to the Wi-Fi module, potentially exposing sensitive data transmitted or processed by the affected component. The CVSS 3.1 base score is 5.5 (medium), with an attack vector of local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). No public exploits are currently known, and no patches have been linked yet. The vulnerability could be leveraged to intercept or leak confidential information from services relying on the Wi-Fi module, especially in environments where devices run HarmonyOS and are accessible to attackers locally. This flaw highlights the importance of strict permission management within OS modules handling network communications. Given Huawei's expanding footprint in consumer electronics, IoT, and telecom infrastructure, this vulnerability could have broader implications if exploited in targeted attacks or espionage campaigns.

For European organizations, the primary impact of CVE-2025-58283 is the potential compromise of confidentiality in wireless communications or services running on Huawei HarmonyOS devices. This could lead to unauthorized disclosure of sensitive data, including corporate or personal information transmitted over Wi-Fi. Although the vulnerability requires local access and user interaction, environments with shared or public access to devices (e.g., offices, public kiosks, or IoT deployments) are at higher risk. The flaw does not affect data integrity or system availability, limiting the scope of damage to information leakage. Organizations relying on Huawei devices for critical communications or infrastructure may face increased risk of espionage or data theft. The absence of known exploits reduces immediate threat but does not eliminate future risk, especially as attackers develop techniques to gain local access or trick users into interaction. The medium severity rating suggests that while the vulnerability is not critical, it warrants timely mitigation to prevent potential confidentiality breaches that could undermine trust and compliance with data protection regulations such as GDPR.

To mitigate CVE-2025-58283, European organizations should implement the following specific measures: 1) Monitor Huawei’s official channels for patches or firmware updates addressing this vulnerability and apply them promptly once available. 2) Restrict physical and local network access to devices running HarmonyOS, especially in shared or public environments, to reduce the likelihood of attacker proximity. 3) Educate users about the risks of interacting with suspicious prompts or applications that could trigger exploitation, minimizing user interaction risks. 4) Conduct audits of device configurations focusing on Wi-Fi module permissions and access controls to identify and remediate overly permissive settings. 5) Employ endpoint detection and response (EDR) solutions capable of monitoring unusual local activity or privilege escalations related to Wi-Fi services. 6) Segment networks to isolate vulnerable devices and limit lateral movement opportunities. 7) For organizations deploying IoT or telecom infrastructure with HarmonyOS, implement strict device onboarding and access policies to prevent unauthorized local access. These targeted actions go beyond generic advice by focusing on the unique attack vector and affected component.
