CVE-2025-64695 identifies a vulnerability in the Windows installer of LogStare Collector, a product by LogStare Inc., specifically affecting versions 2.4.1 and earlier. The issue stems from an uncontrolled search path element, a common security flaw where the installer improperly trusts the order or location of directories it searches for executable components or DLLs during installation. This can allow an attacker with local access to place a malicious executable or DLL in a directory that is searched before the legitimate one, causing the installer to load and execute the attacker's code. The execution occurs with the privileges of the user running the installer, which could be an administrator or standard user depending on context. The vulnerability requires user interaction to launch the installer, and no prior authentication is necessary, but the attacker must have the ability to influence the search path or place files in certain directories accessible to the user. The CVSS v3.0 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity but requiring user interaction and local access. There are no known exploits in the wild at the time of publication, but the vulnerability poses a significant risk especially in environments where LogStare Collector is deployed for security monitoring or log collection. The lack of a patch link indicates that a fix may not yet be publicly available, increasing the urgency for mitigation.

For European organizations, this vulnerability could lead to unauthorized code execution during the installation or upgrade of LogStare Collector, potentially allowing attackers to escalate privileges or compromise system integrity. Since LogStare Collector is used for log collection and security monitoring, exploitation could undermine the security posture by disabling or manipulating logs, hiding malicious activity, or gaining persistent footholds. Confidentiality is at risk as attackers could execute arbitrary code to access sensitive information. Integrity and availability are also threatened, as attackers could alter or disrupt logging functions critical for incident detection and response. The requirement for local access and user interaction limits remote exploitation but insider threats or social engineering attacks could facilitate exploitation. Organizations with strict compliance requirements (e.g., GDPR) could face regulatory and reputational damage if this vulnerability is exploited to breach personal data or critical infrastructure systems.

To mitigate CVE-2025-64695, European organizations should: 1) Avoid running the LogStare Collector installer from untrusted or writable directories; ensure the installer is executed from a secure, trusted location. 2) Restrict write permissions on directories included in the system's search path to prevent attackers from placing malicious files. 3) Verify the digital signature and integrity of the installer before execution to ensure authenticity. 4) Employ application whitelisting to prevent unauthorized executables from running during installation. 5) Use least privilege principles by running installers with the minimum necessary user rights, avoiding administrator privileges unless absolutely required. 6) Monitor and audit installation activities and file system changes during installation to detect suspicious behavior. 7) Stay alert for vendor patches or updates addressing this vulnerability and apply them promptly once available. 8) Educate users and administrators about the risks of running installers from untrusted sources and the importance of verifying software integrity.
