CVE-2025-58292 is a path traversal vulnerability classified under CWE-27 found in Huawei's HarmonyOS, specifically affecting the office service component in versions 5.0.1 and 5.1.0. The vulnerability arises from improper sanitization of file path inputs, allowing an attacker to use directory traversal sequences like 'dir/../../filename' to access unintended file system locations. While this does not lead to unauthorized data access or modification, it can cause a denial of service (DoS) by disrupting the availability of the office service, potentially crashing the service or causing it to malfunction. The CVSS 3.1 score is 3.3 (low), reflecting that exploitation requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), but user interaction (UI:R) is necessary. The scope remains unchanged (S:U), and the impact is limited to availability (A:L) with no confidentiality or integrity impact. No patches have been published yet, and no known exploits are reported in the wild. The vulnerability's exploitation vector suggests that an attacker must have local access to the device and trick a user into interacting with a malicious file path input, limiting the attack surface primarily to insiders or users with physical or remote local access. This vulnerability highlights the importance of input validation and secure file handling in embedded operating systems like HarmonyOS.

For European organizations, the primary impact of CVE-2025-58292 is a potential denial of service affecting the availability of the office service on HarmonyOS devices. This could disrupt productivity and business operations relying on Huawei's HarmonyOS ecosystem, especially in environments where these devices are integrated into office workflows. Although the impact on confidentiality and integrity is null, service unavailability can lead to operational delays and increased support costs. The requirement for local access and user interaction reduces the risk of widespread remote exploitation, but insider threats or compromised local accounts could leverage this vulnerability. Organizations using Huawei HarmonyOS devices in critical roles should be aware of potential service interruptions and plan for incident response accordingly. The lack of known exploits in the wild currently limits immediate risk, but proactive mitigation is advised to prevent future exploitation.

1. Restrict local user permissions on HarmonyOS devices to minimize the risk of unauthorized local access. 2. Educate users to avoid interacting with suspicious file paths or untrusted input that could trigger the vulnerability. 3. Implement monitoring and logging for unusual file path access patterns within the office service to detect potential exploitation attempts. 4. Once Huawei releases patches or updates addressing CVE-2025-58292, apply them promptly to affected devices. 5. Employ application whitelisting or sandboxing techniques to limit the office service's ability to access arbitrary file system locations. 6. Conduct regular security audits and vulnerability assessments on HarmonyOS deployments to identify and remediate similar issues. 7. For organizations with critical operations, consider network segmentation to isolate HarmonyOS devices and reduce the impact of potential DoS conditions.
