CVE-2024-47255 affects 2N Access Commander, a physical access control management software widely used for centralized control of access points. The vulnerability is categorized under CWE-354, indicating improper validation of an integrity check value. This flaw allows a local attacker who already has high privileges on the system to escalate their privileges further, potentially leading to arbitrary code execution with root permissions. The vulnerability exists in versions 3.1.1.2 and earlier. Exploitation requires local access and high privileges, meaning the attacker must already have significant access to the system, but no user interaction is needed. The improper validation likely involves insufficient checks on data integrity or cryptographic verification mechanisms, enabling an attacker to bypass security controls and execute unauthorized commands. While no public exploits have been reported, the ability to gain root-level code execution poses a serious risk to system confidentiality and integrity, potentially allowing attackers to manipulate access control configurations, disable security features, or move laterally within the network. The CVSS v3.1 score of 4.7 reflects a medium severity, primarily due to the requirement for local high privileges and the complexity of exploitation. However, the impact on confidentiality is high, as root access compromises the entire system. The vulnerability is currently published and tracked by the CVE database but lacks an official patch at the time of reporting.

For European organizations, the impact of CVE-2024-47255 can be significant, especially for entities relying on 2N Access Commander to manage physical security across facilities. Compromise of this system could lead to unauthorized physical access, manipulation of access logs, and disruption of security operations. Critical infrastructure sectors such as energy, transportation, and government facilities that use 2N products are particularly vulnerable. The root-level code execution capability means attackers could install persistent backdoors, exfiltrate sensitive data, or disable security mechanisms. Given the local and high privilege requirements, insider threats or attackers who have already breached perimeter defenses pose the greatest risk. The medium CVSS score may underestimate the real-world impact in environments where physical security is tightly integrated with IT systems. Additionally, the lack of known exploits currently provides a window for proactive mitigation before widespread exploitation occurs.

1. Restrict local access to systems running 2N Access Commander to trusted administrators only, employing strict access control policies and monitoring. 2. Implement robust logging and alerting for privilege escalation attempts and unusual system behavior on affected hosts. 3. Use host-based intrusion detection systems (HIDS) to detect unauthorized changes or execution of suspicious code. 4. Regularly audit user privileges and remove unnecessary high-level access to minimize the attack surface. 5. Apply vendor patches or updates as soon as they become available; monitor 2N communications for patch releases. 6. Consider network segmentation to isolate physical access control systems from general IT infrastructure, reducing lateral movement risk. 7. Employ multi-factor authentication for administrative access to reduce the risk of credential compromise. 8. Conduct security awareness training for administrators to recognize and report suspicious activities. 9. If patching is delayed, consider temporary compensating controls such as disabling unnecessary services or restricting execution permissions on critical files related to integrity checks.
