CVE-2025-34075 is a vulnerability identified in HashiCorp's Vagrant product. Although specific technical details and affected versions are not provided, the CVSS 4.0 vector string offers insight into the nature and severity of the vulnerability. The vector AV:L indicates that the attack vector requires local access, meaning an attacker must have some level of access to the victim's machine to exploit the vulnerability. AC:L suggests low attack complexity, implying that once local access is obtained, exploitation does not require advanced skills or conditions. AT:P indicates that the attack requires privileges, specifically low privileges, which means the attacker must have some authenticated access but not necessarily administrative rights. PR:L confirms this low privilege requirement. UI:A means user interaction is required for exploitation, so the attacker must trick or convince a user to perform some action. The vulnerability impacts confidentiality, integrity, and availability to a high degree (VC:H, VI:H, VA:H), indicating that successful exploitation could lead to significant data exposure, unauthorized data modification, and service disruption. The scope is unchanged (SC:N), meaning the vulnerability affects resources within the same security scope without privilege escalation beyond the initial context. No known exploits are reported in the wild, and no patches or affected versions are listed, suggesting this is a newly published vulnerability with limited public technical details. Vagrant is a widely used tool for building and managing virtual machine environments, primarily used by developers and IT professionals to create reproducible development environments. Exploitation of this vulnerability could allow an attacker with local access and low privileges to compromise the confidentiality, integrity, and availability of the virtualized environments managed by Vagrant, potentially leading to data leakage, unauthorized code execution, or denial of service within development or testing environments.

For European organizations, the impact of CVE-2025-34075 can be significant, especially for those relying heavily on Vagrant for development, testing, and deployment workflows. Compromise of Vagrant environments could lead to exposure of sensitive intellectual property, source code, and configuration data. Integrity violations could result in unauthorized changes to development environments, potentially introducing backdoors or malicious code into software supply chains. Availability impacts could disrupt development pipelines, delaying software releases and impacting business operations. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and critical infrastructure, may face compliance risks if confidential data is exposed. Additionally, the requirement for local access and user interaction means insider threats or social engineering attacks could be vectors for exploitation. The lack of patches or mitigations at the time of publication increases the urgency for organizations to assess their exposure and implement compensating controls.

Given the local access and user interaction requirements, European organizations should focus on strengthening endpoint security and user awareness. Specific mitigations include: 1) Restricting local access to systems running Vagrant to trusted personnel only, employing strict access controls and monitoring. 2) Enhancing user training to recognize and prevent social engineering attempts that could trigger exploitation. 3) Implementing application whitelisting and endpoint detection and response (EDR) solutions to detect anomalous behavior related to Vagrant processes. 4) Isolating development environments using network segmentation to limit lateral movement in case of compromise. 5) Regularly auditing and hardening Vagrant configurations and underlying host operating systems. 6) Monitoring vendor communications for patches or updates addressing this vulnerability and applying them promptly once available. 7) Considering temporary suspension or alternative tooling for critical environments if risk is deemed unacceptable until a fix is released.
