CVE-2025-58277 is a vulnerability identified in Huawei's HarmonyOS versions 5.0.1 and 5.1.0, specifically within the Camera application. The flaw is categorized as CWE-200, indicating an exposure of sensitive information to unauthorized actors due to a permission verification bypass. This means that the Camera app fails to properly enforce permission checks, allowing an attacker to bypass these controls and access sensitive data that should be protected. The vulnerability affects service confidentiality but does not impact integrity or availability. According to the CVSS 3.1 vector (AV:P/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N), exploitation requires physical proximity or local network access (Attack Vector: Physical), has a high attack complexity, requires no privileges, but does require user interaction. The scope is unchanged, and the confidentiality impact is high, while integrity and availability impacts are none. No patches or known exploits are currently available, and the vulnerability was published on October 11, 2025. The lack of known exploits suggests it is not yet actively targeted, but the potential for sensitive data leakage remains a concern. The vulnerability could be exploited by tricking users into interacting with malicious content or apps that leverage the permission bypass to access camera data or related sensitive information. Given Huawei's significant market share in certain regions and the increasing use of HarmonyOS in IoT and mobile devices, this vulnerability could have broader implications if exploited at scale.

For European organizations, the primary impact of CVE-2025-58277 lies in the potential unauthorized exposure of sensitive information captured or processed by the Camera app on HarmonyOS devices. This could lead to privacy breaches, leakage of confidential corporate or personal data, and potential espionage risks, especially in sectors handling sensitive or classified information such as government, defense, telecommunications, and critical infrastructure. Although the vulnerability does not affect system integrity or availability, the confidentiality breach could undermine trust in Huawei devices and complicate compliance with European data protection regulations like GDPR. The requirement for user interaction and high attack complexity somewhat limits the risk but does not eliminate it, particularly in environments where users may be targeted with social engineering or phishing attacks. Organizations relying on Huawei HarmonyOS devices should consider the risk in their threat models, especially if these devices are used in sensitive operational contexts or connected to corporate networks.

To mitigate CVE-2025-58277, European organizations should implement several specific measures beyond generic patching advice: 1) Enforce strict network segmentation and limit network access to Huawei HarmonyOS devices, especially restricting access to the Camera app's services. 2) Educate users about the risks of interacting with untrusted content or applications that could trigger the permission bypass exploit, emphasizing cautious behavior with camera permissions. 3) Deploy mobile device management (MDM) solutions to monitor and control app permissions and detect anomalous behavior related to camera access. 4) Where possible, disable or restrict the Camera app on devices used in high-security environments or replace them with devices not affected by this vulnerability. 5) Monitor Huawei’s security advisories closely for patches or updates addressing this vulnerability and apply them promptly once available. 6) Conduct regular security audits and penetration testing focusing on mobile device security and permission enforcement. 7) Implement endpoint detection and response (EDR) tools capable of identifying suspicious activities related to camera access on HarmonyOS devices.
