CVE-2025-2102 is a medium-severity vulnerability identified as CWE-59, which pertains to Improper Link Resolution Before File Access, commonly known as 'Link Following'. This vulnerability affects the HYPR Passwordless authentication product on Windows platforms, specifically versions prior to 10.1. The flaw arises when the software improperly resolves symbolic links or shortcuts before accessing files, potentially allowing an attacker to manipulate the file path resolution process. This can lead to privilege escalation, where an attacker with some level of access could exploit the vulnerability to gain higher privileges on the affected system. The CVSS 4.0 base score of 5.7 reflects a medium severity, with the vector indicating that the attack requires local access (AV:L), high attack complexity (AC:H), privileges (PR:H), and user interaction (UI:A). The vulnerability impacts confidentiality, integrity, and availability to varying degrees, with a particular emphasis on integrity and availability due to the privilege escalation potential. No known exploits are currently reported in the wild, and no patches or mitigations have been officially published at the time of this analysis. The vulnerability was reserved in March 2025 and published in May 2025, indicating recent discovery and disclosure.

For European organizations, the impact of CVE-2025-2102 could be significant, especially for those relying on HYPR Passwordless for secure authentication. Privilege escalation vulnerabilities can allow attackers to bypass security controls, potentially leading to unauthorized access to sensitive data, disruption of services, or further lateral movement within networks. Organizations in sectors with high security requirements such as finance, healthcare, government, and critical infrastructure could face increased risks. The requirement for local access and user interaction somewhat limits remote exploitation, but insider threats or compromised endpoints could still leverage this vulnerability. Given the growing adoption of passwordless authentication solutions in Europe to enhance security and user experience, this vulnerability could undermine trust and security postures if not addressed promptly.

European organizations using HYPR Passwordless should take immediate steps to mitigate this vulnerability. First, they should monitor HYPR’s official channels for patches or updates addressing CVE-2025-2102 and apply them as soon as they become available. Until a patch is released, organizations should restrict local access to systems running HYPR Passwordless, enforce strict endpoint security controls, and monitor for unusual privilege escalation attempts. Implementing application whitelisting and restricting the creation and resolution of symbolic links or shortcuts in sensitive directories can reduce exploitation risk. Additionally, conducting regular audits of user privileges and employing behavior-based anomaly detection can help identify exploitation attempts early. Training users to recognize and avoid suspicious interactions that could trigger the vulnerability is also advisable. Finally, organizations should consider isolating critical systems and limiting administrative privileges to minimize the attack surface.
