CVE-2025-64299 is a vulnerability identified in LogStare Collector for Windows, specifically affecting versions 2.4.1 and earlier. The issue arises from improper handling of password hash data within the application, which allows an administrative user to access password hashes belonging to other users. The vulnerability is classified with a CVSS 3.0 base score of 4.9 (medium severity), reflecting that it requires high privileges (administrative rights) but can be exploited remotely without user interaction. The flaw compromises confidentiality by exposing sensitive credential information, although it does not affect data integrity or system availability. Since password hashes can be subjected to offline cracking attacks, an attacker with administrative access could potentially escalate privileges or move laterally within the network by leveraging cracked credentials. No public exploits have been reported to date, but the presence of this vulnerability poses a risk especially in environments where administrative accounts are shared or poorly controlled. The vulnerability highlights a design or implementation flaw in how LogStare Collector manages sensitive authentication data, failing to adequately isolate or protect password hashes from privileged users. This could be due to insecure storage, transmission, or logging practices within the software. Organizations using affected versions should prioritize patching once updates are released and review access controls to limit administrative privileges to trusted personnel only.

For European organizations, the exposure of password hashes through this vulnerability can lead to significant confidentiality breaches, especially in sectors where LogStare Collector is used for centralized log management and security monitoring. Compromised credentials can facilitate unauthorized access, lateral movement, and potential data exfiltration within corporate networks. Critical infrastructure operators, financial institutions, and government agencies relying on LogStare Collector may face increased risk of insider threats or external attackers leveraging stolen hashes. Although exploitation requires administrative privileges, the risk is amplified in environments with weak privilege management or where administrative credentials are shared or reused. The vulnerability does not directly impact system availability or data integrity, but the downstream effects of credential compromise can lead to broader security incidents. Given the medium severity rating and the nature of the vulnerability, organizations should consider this a moderate risk that requires timely remediation to prevent escalation and maintain compliance with data protection regulations such as GDPR.

1. Upgrade LogStare Collector to a version later than 2.4.1 once the vendor releases a patch addressing CVE-2025-64299. 2. Until a patch is available, restrict administrative access to the LogStare Collector system to a minimal number of trusted personnel and enforce strong authentication mechanisms such as multi-factor authentication (MFA). 3. Implement strict access controls and audit logging to monitor administrative actions and detect any unauthorized attempts to access password hashes. 4. Regularly review and rotate administrative credentials to reduce the risk of credential reuse or compromise. 5. Employ network segmentation to isolate LogStare Collector servers from less trusted network zones, limiting exposure to potential attackers. 6. Conduct internal security assessments and penetration tests focusing on privilege escalation and credential theft scenarios related to LogStare Collector. 7. Educate system administrators about the risks of credential exposure and best practices for secure password management. 8. Monitor threat intelligence feeds for any emerging exploits targeting this vulnerability and respond accordingly.
