CVE-2025-13152 is a vulnerability classified under CWE-427 (Uncontrolled Search Path Element) affecting Lenovo One Client. This vulnerability was discovered during an internal security assessment and involves DLL hijacking, where the application improperly controls the search path for dynamic link libraries. An attacker with local authenticated access can exploit this flaw by placing a malicious DLL in a location that the application searches before the legitimate DLL, causing the malicious code to be loaded and executed with elevated privileges. The CVSS 4.0 score of 8.5 indicates a high severity, with an attack vector limited to local access (AV:L), low attack complexity (AC:L), no attack prerequisites (AT:N), and requiring privileges (PR:L) but no user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability at a high level due to the potential for privilege escalation and arbitrary code execution. No public exploits are currently known, and no patches have been released yet, emphasizing the need for proactive mitigation. The vulnerability does not require user interaction, increasing the risk in environments where local access is possible. Lenovo One Client is used in enterprise environments for device management and connectivity, making this vulnerability particularly relevant for organizations relying on this software for operational continuity and security.

For European organizations, this vulnerability poses a significant risk as it allows local authenticated users to escalate privileges, potentially leading to full system compromise. Confidentiality may be breached if attackers gain access to sensitive data through elevated privileges. Integrity is at risk as attackers could modify system files or configurations, and availability could be disrupted by malicious code execution. Organizations with Lenovo One Client deployed on critical infrastructure or enterprise endpoints could face operational disruptions and data breaches. The requirement for local authentication limits remote exploitation but insider threats or compromised user accounts could leverage this vulnerability. The absence of known exploits reduces immediate risk but also means organizations must be vigilant and proactive. The impact is heightened in sectors with strict regulatory requirements such as finance, healthcare, and government within Europe.

1. Immediately restrict local user permissions to minimize the number of users with authenticated access capable of exploiting this vulnerability. 2. Monitor and audit local file system locations where DLLs are loaded to detect unauthorized or suspicious DLL files. 3. Implement application whitelisting and code integrity policies to prevent unauthorized DLL execution. 4. Once Lenovo releases patches or updates, prioritize their deployment across all affected systems. 5. Use tools to analyze and harden DLL search paths, ensuring they do not include insecure directories such as user-writable folders. 6. Educate IT staff and users about the risks of local privilege escalation and enforce strict endpoint security controls. 7. Employ endpoint detection and response (EDR) solutions to identify anomalous behavior indicative of DLL hijacking attempts. 8. Consider network segmentation to limit lateral movement from compromised endpoints. 9. Regularly review and update security policies related to local access and software installation rights.
