CVE-2025-0372 is a medium-severity vulnerability classified as CWE-362, which involves a race condition due to improper synchronization when concurrently accessing shared resources in the HYPR Passwordless authentication product on Windows platforms. This flaw allows an attacker with limited privileges to escalate their privileges by exploiting the timing window where concurrent execution threads improperly handle shared resources, potentially leading to unauthorized access or execution of privileged operations. The vulnerability affects versions of HYPR Passwordless prior to 10.1. The race condition arises because the software does not adequately synchronize access to critical sections or shared data structures, enabling an attacker to manipulate the execution flow or state. The CVSS 4.0 vector indicates that exploitation requires local access (AV:L), high attack complexity (AC:H), partial privileges (PR:L), and user interaction (UI:A). The impact on confidentiality is low, but integrity and availability impacts are high, with a limited scope and low vector complexity. No known exploits are currently in the wild, and no patches have been linked yet. This vulnerability is significant because HYPR Passwordless is used for secure passwordless authentication, and privilege escalation could undermine the security guarantees of the authentication process, potentially allowing attackers to gain elevated system access or bypass security controls.

For European organizations, this vulnerability poses a risk primarily to environments using HYPR Passwordless on Windows systems. Privilege escalation vulnerabilities can lead to attackers gaining administrative or system-level access, which can compromise sensitive data, disrupt operations, and facilitate lateral movement within networks. Given the increasing adoption of passwordless authentication solutions in Europe to enhance security and comply with regulations like GDPR, exploitation of this flaw could undermine trust in such technologies and lead to data breaches or service disruptions. Organizations in sectors with high security requirements—such as finance, healthcare, and critical infrastructure—may face significant operational and reputational damage if attackers exploit this vulnerability. Additionally, the requirement for local access and user interaction limits remote exploitation but does not eliminate risk from insider threats or social engineering attacks. The medium severity suggests that while the vulnerability is serious, it is not trivially exploitable remotely, but still warrants prompt attention to prevent privilege escalation scenarios.

European organizations should prioritize upgrading HYPR Passwordless to version 10.1 or later once available, as this will contain the fix for the race condition vulnerability. Until patches are released, organizations should implement strict access controls to limit local access to trusted users only, reducing the attack surface. Employing endpoint detection and response (EDR) solutions can help detect suspicious privilege escalation attempts. Additionally, enforcing multi-factor authentication (MFA) at the system level can mitigate the impact of compromised credentials. Organizations should conduct thorough code reviews and testing for race conditions in custom integrations with HYPR Passwordless. Applying Windows security best practices, such as least privilege principles and regular auditing of user privileges, will further reduce risk. Finally, user training to recognize and avoid social engineering tactics that could facilitate local access or user interaction exploitation is recommended.
