CVE-2024-37767 is a vulnerability identified in the 14Finger software version 1.1, specifically affecting the /api/admin/user component. The root cause is insecure permissions that allow unauthenticated attackers to send crafted GET requests to this API endpoint and retrieve all user information stored or managed by the system. This vulnerability is classified under CWE-306, which denotes missing authentication for critical functions. The vulnerability is remotely exploitable over the network without requiring any privileges or user interaction, making it highly accessible to attackers. The CVSS 3.1 score of 7.5 reflects a high severity primarily due to the complete compromise of confidentiality, while integrity and availability remain unaffected. The lack of authentication enforcement on an administrative API endpoint is a critical security oversight, exposing sensitive user data to unauthorized parties. Although no public exploits or patches are currently available, the vulnerability poses a significant risk to organizations using this software. The absence of a patch necessitates immediate compensating controls to prevent exploitation. This vulnerability highlights the importance of enforcing strict access controls and authentication mechanisms on all administrative interfaces, especially APIs that expose sensitive user data.

The primary impact of CVE-2024-37767 is a total breach of user data confidentiality. Attackers exploiting this vulnerability can access sensitive user information without any authentication, potentially leading to identity theft, privacy violations, and further targeted attacks such as phishing or social engineering. Organizations relying on 14Finger v1.1 risk exposure of their user databases, which can damage reputation, incur regulatory penalties (especially under data protection laws like GDPR or CCPA), and result in financial losses. Since the vulnerability does not affect integrity or availability, the system’s operation remains intact, but the data exposure alone is critical. The ease of exploitation (no authentication or user interaction required) increases the likelihood of attacks, especially from opportunistic threat actors scanning for vulnerable endpoints. The absence of known exploits in the wild currently limits immediate widespread impact, but the vulnerability remains a significant risk until remediated. Organizations in sectors handling sensitive user data such as healthcare, finance, and government are particularly vulnerable to the consequences of this data exposure.

1. Immediately restrict network access to the /api/admin/user endpoint using firewalls or network segmentation to limit exposure to trusted internal IP addresses only. 2. Implement strong authentication and authorization controls on the affected API endpoint, ensuring only authorized administrators can access user data. 3. Monitor API logs for unusual or unauthorized GET requests targeting /api/admin/user to detect potential exploitation attempts. 4. If possible, disable or remove the vulnerable API endpoint until a vendor patch or update is available. 5. Engage with the 14Finger vendor or software maintainers to obtain official patches or security updates addressing this vulnerability. 6. Conduct a thorough audit of all administrative APIs in the environment to verify that similar insecure permission issues do not exist elsewhere. 7. Educate development and security teams on secure API design principles, particularly enforcing authentication on all sensitive endpoints. 8. Prepare incident response plans to quickly address any detected exploitation attempts or data breaches related to this vulnerability.
