CVE-2025-58285 identifies a permissions and access control vulnerability (CWE-264) within the media module of Huawei's HarmonyOS versions 5.0.1 and 5.1.0. The flaw stems from inadequate enforcement of permission checks, allowing an attacker with local access and the ability to interact with the user interface to exploit the vulnerability. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L) indicates that the attack requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), and user interaction (UI:R). The scope remains unchanged (S:U), and the impact affects confidentiality, integrity, and availability at a low level (C:L/I:L/A:L). Exploiting this vulnerability could allow unauthorized access or manipulation of media services, potentially leaking sensitive information or disrupting media functionalities. Although no known exploits are currently reported, the vulnerability's presence in a core OS component used in Huawei devices means it could be leveraged in targeted attacks. The lack of published patches necessitates proactive mitigation. This vulnerability highlights the importance of robust permission enforcement in OS modules that handle sensitive data and services.

For European organizations, the vulnerability poses a moderate risk primarily to confidentiality and integrity of media-related services on Huawei devices running affected HarmonyOS versions. Potential impacts include unauthorized access to sensitive media content, manipulation of media services, or disruption of availability, which could affect business communications, multimedia applications, or data privacy compliance. Organizations relying on Huawei mobile devices or IoT products with HarmonyOS may face increased risk of insider threats or local attacker exploitation. The impact is more pronounced in sectors handling sensitive or regulated data such as telecommunications, media companies, and government agencies. While remote exploitation is not possible, the requirement for local access and user interaction means physical device security and user awareness are critical. The absence of known exploits reduces immediate risk but does not eliminate the threat of future targeted attacks. Overall, the vulnerability could undermine trust in Huawei devices and complicate compliance with European data protection regulations if exploited.

1. Restrict physical and local access to devices running affected HarmonyOS versions to trusted personnel only. 2. Educate users on the risks of interacting with untrusted applications or prompts that could trigger exploitation. 3. Implement strict device usage policies and monitor for unusual local activity or privilege escalations. 4. Employ endpoint detection and response (EDR) solutions capable of identifying suspicious local interactions or media module anomalies. 5. Regularly audit installed applications and permissions to ensure no unauthorized apps have access to sensitive media functions. 6. Coordinate with Huawei for timely updates and patches; apply them immediately upon release. 7. For critical environments, consider device segmentation or limiting use of affected Huawei devices until patches are available. 8. Maintain comprehensive backups of important data to mitigate potential availability impacts. 9. Engage in threat intelligence sharing within industry groups to stay informed about emerging exploit attempts. 10. Review and enhance access control policies specifically around media and multimedia services on devices.
