CVE-2025-23358 is a vulnerability classified under CWE-427 (Uncontrolled Search Path Element) found in the NVIDIA NVApp installer for Windows. The issue arises because the installer improperly manages the search path elements, allowing a local attacker to influence the loading of executable files or DLLs by placing malicious files in directories that are searched before legitimate ones. This can lead to arbitrary code execution within the context of the installer, which typically runs with elevated privileges. The attacker requires local access with limited privileges and some user interaction to trigger the exploit. Successful exploitation results in escalation of privileges, enabling the attacker to gain higher system rights, potentially leading to full system compromise. The vulnerability affects all NVApp versions prior to 11.0.5.260. The CVSS 3.1 base score is 8.2, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity but requiring local access and user interaction. No patches or exploits are currently publicly available, but the vulnerability is officially published and should be addressed promptly.

For European organizations, this vulnerability poses a significant threat, especially in environments where NVIDIA NVApp is installed, such as workstations used for gaming, graphic design, AI development, or scientific computing. Exploitation can lead to unauthorized code execution and privilege escalation, potentially allowing attackers to install persistent malware, steal sensitive data, or disrupt operations. The risk is heightened in organizations with many local users or shared workstations, as local attackers or malicious insiders could exploit this flaw. Additionally, the compromise of privileged accounts could facilitate lateral movement and further attacks within corporate networks. The impact extends to confidentiality, integrity, and availability of affected systems, making it critical for organizations to address the vulnerability promptly to avoid potential data breaches or operational disruptions.

Organizations should immediately inventory their systems to identify installations of NVIDIA NVApp and verify the version in use. Since no patch is currently available, interim mitigations include restricting local user permissions to prevent unauthorized file placement in directories searched by the installer. Implement application whitelisting to block execution of unauthorized binaries and monitor for suspicious file creation or modification in relevant directories. Educate users to avoid running untrusted installers or applications and limit local administrative privileges. Once NVIDIA releases a patch or update beyond version 11.0.5.260, prioritize deployment across all affected systems. Additionally, employ endpoint detection and response (EDR) tools to detect anomalous behaviors indicative of exploitation attempts. Regularly review and harden system configurations to minimize the attack surface related to local privilege escalation vulnerabilities.
