CVE-2025-27247: CWE-281 Improper Preservation of Permissions in OpenHarmony OpenHarmony
in OpenHarmony v5.0.3 and prior versions allow a local attacker cause information leak through get permission.
AI Analysis
Technical Summary
CVE-2025-27247 is a vulnerability identified in OpenHarmony version 5.0.3 and earlier, specifically affecting version 5.0.1. The issue is classified under CWE-281, which pertains to improper preservation of permissions. This vulnerability allows a local attacker to cause an information leak by exploiting the 'get permission' functionality. The flaw arises because the system does not correctly maintain or enforce permission boundaries, enabling unauthorized access to sensitive information. The attack vector requires local access (AV:L), low attack complexity (AC:L), and low privileges (PR:L), but does not require user interaction (UI:N). The scope is unchanged (S:U), and the impact is primarily on confidentiality (C:H), with no impact on integrity (I:N) or availability (A:N). The CVSS v3.1 base score is 5.5, indicating a medium severity level. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability could be leveraged by an attacker with local access to the device running OpenHarmony to extract sensitive data that should otherwise be protected by permission controls. OpenHarmony is an open-source operating system designed for IoT and smart devices, meaning this vulnerability could affect a wide range of embedded systems and consumer electronics that rely on this platform.
Potential Impact
For European organizations, the impact of CVE-2025-27247 depends largely on the adoption of OpenHarmony-based devices within their infrastructure or supply chains. Given OpenHarmony's focus on IoT and smart devices, sectors such as manufacturing, smart city infrastructure, healthcare, and telecommunications could be affected if they deploy devices running vulnerable versions. The information leak could expose sensitive operational data, user information, or device configurations, potentially leading to privacy violations or aiding further attacks. Although the vulnerability requires local access, in environments where physical security is less stringent or where insider threats exist, this could be a significant risk. Additionally, compromised IoT devices could serve as footholds for lateral movement within networks. The medium severity rating suggests that while the vulnerability is not critical, it still poses a meaningful risk, especially in high-security environments or where sensitive data is processed. European organizations must consider the regulatory implications of data leaks under GDPR, which could lead to compliance issues and fines if personal data is exposed.
Mitigation Recommendations
To mitigate this vulnerability, European organizations should first identify all devices running OpenHarmony, particularly version 5.0.3 and earlier, including 5.0.1. Since no official patch links are currently available, organizations should monitor OpenHarmony vendor communications for updates or patches addressing CVE-2025-27247. In the interim, organizations should enforce strict physical and logical access controls to limit local access to devices, including the use of secure boot, device hardening, and network segmentation to isolate vulnerable devices. Implementing robust monitoring and logging can help detect unauthorized access attempts. Additionally, organizations should review and tighten permission configurations on affected devices to minimize the risk of unauthorized data access. Where possible, replacing or upgrading devices to versions confirmed to be free of this vulnerability is advisable. Finally, educating staff about the risks of local attacks and insider threats can reduce the likelihood of exploitation.
