CVE-2024-13417 is a vulnerability classified under CWE-248 (Uncaught Exception) affecting 2N OS, specifically versions 2.45 and prior, used in RFID-equipped 2N devices. The flaw arises when specially crafted payloads are sent to the RFID reader component, causing the device software to throw an uncaught exception. This exception leads to a denial-of-service (DoS) condition where the RFID reader becomes non-functional until the device undergoes a restart, after which normal operation resumes. The vulnerability impacts availability but does not compromise confidentiality or integrity. Exploitation requires network-level access to the RFID reader interface but does not require authentication or user interaction, making it relatively easy to exploit in environments where the RFID interface is exposed or accessible. The CVSS v3.1 base score is 4.6, reflecting a medium severity level primarily due to the impact on availability and the attack vector being physical or local network access (AV:P - physical). 2N has addressed this vulnerability in version 2.46 of 2N OS, and customers are advised to update promptly. No public exploits or active exploitation campaigns have been reported. The vulnerability highlights the importance of robust input validation and exception handling in embedded device firmware, especially for access control systems that are critical for physical security.

For European organizations, the primary impact of CVE-2024-13417 is the potential disruption of physical access control systems relying on 2N RFID devices. A successful exploit could cause temporary denial of service, preventing authorized personnel from gaining access to secured facilities until the affected device is restarted. This could lead to operational delays, security policy enforcement gaps, and potential safety risks in sensitive environments such as government buildings, transportation hubs, healthcare facilities, and critical infrastructure. While the vulnerability does not allow data theft or device takeover, the availability impact could be significant in high-security or high-availability contexts. Organizations with large deployments of 2N RFID systems should consider the risk of coordinated attacks causing widespread access denial. The lack of known exploits reduces immediate risk, but the ease of exploitation and potential operational impact warrant proactive mitigation.

1. Immediately update all 2N RFID-equipped devices to 2N OS version 2.46 or later, which contains the fix for this vulnerability. 2. Restrict network access to the RFID reader interfaces to trusted and authenticated management networks only, minimizing exposure to untrusted actors. 3. Implement network segmentation and firewall rules to isolate access control devices from general user networks and the internet. 4. Monitor device logs and network traffic for unusual or malformed payloads targeting RFID readers that could indicate attempted exploitation. 5. Establish operational procedures for rapid device restart or failover in case of detected denial-of-service conditions. 6. Coordinate with 2N support for firmware updates and security advisories to stay informed of any emerging threats or patches. 7. Conduct regular security audits and penetration testing focused on physical access control systems to identify and remediate potential weaknesses.
