CVE-2025-64299 is a vulnerability identified in LogStare Collector for Windows versions 2.4.1 and earlier, where the software improperly handles password hash data. Specifically, administrative users can obtain password hashes belonging to other users due to insecure insertion or transmission of sensitive information within the application’s data flows. This flaw arises from inadequate segregation or protection of credential data in the log collection process. The vulnerability requires administrative privileges to exploit, meaning that an attacker must already have elevated access to the system. No user interaction is needed, and the vulnerability affects confidentiality but not integrity or availability. The CVSS 3.0 score is 4.9 (medium severity), reflecting the moderate risk posed by the exposure of password hashes, which could be leveraged for offline password cracking attacks or lateral movement within a network. There are no known exploits in the wild as of the published date, but the vulnerability is publicly disclosed and should be addressed promptly. The lack of patch links suggests a fix may be forthcoming or that users should contact the vendor for updates. LogStare Collector is used for centralized log collection and management, often in enterprise environments, making the confidentiality of credentials critical to maintaining secure operations.

For European organizations, the exposure of password hashes through this vulnerability poses a significant confidentiality risk. If an attacker with administrative access extracts these hashes, they could perform offline brute-force or dictionary attacks to recover plaintext passwords, potentially escalating privileges or moving laterally across networks. This is particularly concerning for organizations subject to stringent data protection regulations such as GDPR, where unauthorized access to user credentials could lead to compliance violations and reputational damage. Critical infrastructure operators and enterprises using LogStare Collector for security monitoring may face increased risk of insider threats or compromised administrative accounts. The vulnerability does not directly affect system availability or integrity, but the indirect consequences of credential compromise could lead to broader security incidents. The medium severity rating reflects the need for timely remediation but indicates that exploitation requires existing administrative access, somewhat limiting the attack surface.

Organizations should immediately inventory their use of LogStare Collector and identify any instances running version 2.4.1 or earlier. They should restrict administrative privileges to trusted personnel only and implement strict access controls and monitoring on systems running the affected software. Until a vendor patch is available, consider isolating LogStare Collector servers to minimize exposure and monitor logs for unusual access patterns or attempts to extract credential data. Employ multi-factor authentication (MFA) for administrative accounts to reduce the risk of credential compromise. Additionally, enforce strong password policies and consider using password hash salting and key stretching techniques if supported by the environment. Regularly audit and rotate credentials to limit the window of opportunity for attackers. Engage with LogStare Inc. for official patches or updates and apply them promptly once released. Finally, incorporate this vulnerability into incident response plans to quickly detect and respond to any exploitation attempts.
