CVE-2025-67442 is a directory traversal vulnerability identified in EVE-NG version 6.4.0-13-PRO, a popular network emulation platform used for designing, testing, and training on network topologies. The vulnerability resides in the /api/export interface, which allows authenticated users to export lab files. This interface fails to properly validate and filter user-supplied file path parameters, enabling attackers to traverse directories outside the intended export scope. By manipulating these parameters, an attacker could access arbitrary files on the server, potentially exposing sensitive configuration files, credentials, or other critical data stored on the system. Although exploitation requires authentication, the lack of effective input sanitization increases the risk of unauthorized data disclosure within organizations using this platform. No CVSS score has been assigned yet, and no known exploits are reported in the wild. However, the vulnerability's nature suggests a significant risk to confidentiality and possibly integrity if sensitive files are modified. The vulnerability affects network engineers, security researchers, and organizations relying on EVE-NG for network simulation and training, which are common in enterprise and academic environments.

For European organizations, the impact of CVE-2025-67442 could be substantial, especially for those using EVE-NG in network design, security testing, or educational contexts. Unauthorized access to lab files or system configurations could lead to exposure of sensitive network topologies, credentials, or proprietary configurations, undermining confidentiality and potentially enabling further attacks. This could disrupt network planning and security validation processes, delaying projects and increasing operational risk. Organizations in sectors such as telecommunications, finance, and critical infrastructure, which often use network emulation tools for testing, may face increased risk of intellectual property theft or targeted attacks. Additionally, exposure of sensitive data could lead to regulatory compliance issues under GDPR if personal or sensitive information is involved. The absence of known exploits reduces immediate risk, but the vulnerability's presence in a widely used tool necessitates prompt attention to prevent future exploitation.

To mitigate CVE-2025-67442, organizations should implement the following specific measures: 1) Restrict access to the /api/export interface strictly to trusted and necessary users by enforcing strong authentication and role-based access controls. 2) Apply input validation and sanitization on all file path parameters to prevent directory traversal sequences such as '../'. 3) Monitor API usage logs for unusual or unauthorized export requests that may indicate exploitation attempts. 4) If available, apply vendor patches or updates addressing this vulnerability promptly. 5) In the absence of patches, consider disabling the export API or isolating the EVE-NG server within a segmented network zone to limit exposure. 6) Conduct regular security audits and penetration tests focusing on API endpoints to detect similar vulnerabilities. 7) Educate users about the risks of sharing credentials and the importance of secure authentication practices. These targeted actions go beyond generic advice by focusing on the specific vulnerable interface and operational context of EVE-NG.
