CVE-2025-58289 identifies a business logic error classified under CWE-840 within Huawei's HarmonyOS print module, specifically affecting versions 5.0.1 and 5.1.0. The vulnerability arises from improper exception handling during printing operations, which can cause the system to behave unexpectedly or crash, impacting availability. The CVSS 3.1 base score is 5.9, reflecting a medium severity level. The attack vector is local (AV:L), meaning an attacker must have local access to the device to exploit the flaw. No privileges are required (PR:N), and no user interaction is necessary (UI:N), which lowers the barrier for exploitation once local access is obtained. The vulnerability affects confidentiality, integrity, and availability to a limited extent, with availability being the primary concern due to potential denial-of-service conditions. No public exploits have been reported, and no patches are currently linked, indicating that remediation is pending. The flaw is a business logic error, which typically involves incorrect implementation of intended functionality rather than memory corruption or code execution, making exploitation more nuanced but still impactful. This vulnerability could be leveraged by attackers with local access to disrupt printing services or cause system instability on HarmonyOS devices, which are increasingly used in consumer and enterprise environments.

For European organizations, the primary impact of CVE-2025-58289 is on system availability, particularly affecting devices running HarmonyOS that utilize printing services. Disruptions could lead to denial-of-service conditions, impacting business operations reliant on printing workflows, such as document processing in offices or manufacturing environments. Although the confidentiality and integrity impacts are limited, availability issues can cause operational delays and productivity losses. The requirement for local access reduces the risk of remote exploitation but raises concerns for insider threats or compromised local networks. Organizations with Huawei HarmonyOS devices integrated into their IT infrastructure may face increased risk if attackers gain physical or local network access. The lack of known exploits in the wild currently limits immediate threat, but the vulnerability should be addressed proactively to prevent future exploitation. Given Huawei's market presence in Europe, especially in countries with significant Huawei device adoption, the impact could be more pronounced in those regions.

1. Monitor Huawei’s official security advisories for patches addressing CVE-2025-58289 and apply them promptly once available. 2. Restrict local access to HarmonyOS devices, especially those handling printing tasks, through physical security controls and network segmentation to reduce the attack surface. 3. Implement strict user access controls and authentication mechanisms to prevent unauthorized local access. 4. Audit and monitor printing services and system logs for unusual behavior or crashes that may indicate exploitation attempts. 5. Educate users and administrators about the risks of local access vulnerabilities and enforce policies limiting the use of untrusted peripherals or local connections. 6. Consider deploying endpoint detection and response (EDR) solutions capable of identifying abnormal process behavior related to printing modules. 7. Where feasible, isolate critical printing infrastructure from general user devices running HarmonyOS to contain potential impacts.
