CVE-2025-58285 is a permission control vulnerability identified in the media module of Huawei's HarmonyOS versions 5.0.1 and 5.1.0. The flaw is categorized under CWE-264, indicating improper permissions, privileges, or access controls. Specifically, the vulnerability allows an attacker with local access and requiring user interaction to exploit the media module, potentially compromising service confidentiality, integrity, and availability to a limited extent. The CVSS v3.1 score is 5.3 (medium), with the vector AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L, meaning the attack requires local access, low attack complexity, no privileges, user interaction, and impacts confidentiality, integrity, and availability at a low level. No public exploits or patches are currently available, but the vulnerability's presence in a core OS module that handles media services could allow unauthorized access or manipulation of media-related data or services. This could lead to leakage or alteration of sensitive media content or disruption of media functionalities. The vulnerability's exploitation scope is limited to local users who can interact with the device, reducing the risk of remote attacks but still posing a threat in scenarios where devices are shared or physically accessible. The issue highlights the importance of robust permission enforcement in OS modules handling sensitive data. Given Huawei's increasing deployment of HarmonyOS in smartphones, IoT devices, and other consumer electronics, this vulnerability could impact a broad user base.

For European organizations, the impact of CVE-2025-58285 centers on potential confidentiality breaches and service disruptions in devices running HarmonyOS, particularly those used in corporate or sensitive environments. Unauthorized access to media services could lead to leakage of sensitive audio, video, or image data, affecting privacy and compliance with data protection regulations such as GDPR. Integrity impacts could allow tampering with media content, undermining trust in recorded or transmitted information. Availability impacts, though low, could disrupt media functionalities critical for communication or operational processes. The requirement for local access and user interaction limits the threat to scenarios involving insider threats, physical device compromise, or social engineering. Organizations relying on Huawei devices for communication, collaboration, or IoT deployments may face operational risks and reputational damage if exploited. Additionally, the lack of available patches increases exposure time. Overall, while the vulnerability is not critical, it poses a meaningful risk to confidentiality and operational integrity in environments where HarmonyOS devices are prevalent.

1. Monitor Huawei's official security advisories for patches addressing CVE-2025-58285 and apply them promptly once released. 2. Restrict physical and local access to devices running HarmonyOS, especially in sensitive or corporate environments, to reduce exploitation risk. 3. Implement strict user privilege management to limit the ability of local users to interact with media modules unnecessarily. 4. Employ endpoint security solutions capable of detecting anomalous access or behavior related to media services on HarmonyOS devices. 5. Educate users about the risks of social engineering and the importance of not interacting with suspicious prompts or applications that could trigger exploitation. 6. Where feasible, isolate HarmonyOS devices from critical networks or sensitive data environments to contain potential impacts. 7. Conduct regular audits of device permissions and access controls to ensure compliance with security policies. 8. Collaborate with Huawei support channels to gain early insights into patch availability and mitigation guidance.
