CVE-2024-47253 is a path traversal vulnerability identified in 2N Access Commander, a widely used access control management system. The flaw exists in versions up to 3.1.1.2 and allows an attacker who already has administrative privileges to bypass pathname restrictions and write arbitrary files anywhere on the filesystem. This improper limitation of pathname inputs (CWE-22) can be exploited to place malicious files that may lead to arbitrary remote code execution, compromising the system's confidentiality, integrity, and availability. The vulnerability does not affect users with lower privilege roles, limiting the attack surface to administrators or similarly privileged users. The CVSS v3.1 score of 7.2 indicates a high-severity issue with network attack vector, low attack complexity, and no user interaction required. Although no known exploits are currently in the wild, the potential for severe impact is significant, especially in environments where 2N Access Commander controls physical access and security policies. The vulnerability highlights the importance of secure input validation and strict privilege management in access control systems.

For European organizations, the impact of CVE-2024-47253 can be substantial. Organizations relying on 2N Access Commander for physical access control, such as government buildings, critical infrastructure, healthcare facilities, and corporate campuses, face risks of unauthorized system manipulation and potential full compromise. An attacker exploiting this vulnerability could deploy malicious code, disrupt access control operations, or exfiltrate sensitive data. This could lead to physical security breaches, operational downtime, and regulatory non-compliance under GDPR and other data protection laws. The requirement for administrative privileges reduces the likelihood of widespread exploitation but elevates the risk if insider threats or compromised admin accounts exist. The vulnerability could also be leveraged as a pivot point for broader network intrusion within European enterprises, amplifying the threat landscape.

Immediate mitigation steps include restricting administrative access to trusted personnel and enforcing strong authentication mechanisms such as multi-factor authentication (MFA) for all admin accounts. Organizations should monitor administrative activities and audit logs for suspicious behavior indicative of exploitation attempts. Since no patch links are currently available, organizations must engage with 2N support for updates or workarounds. Network segmentation should isolate the 2N Access Commander system from less trusted network zones to limit exposure. Implementing application whitelisting and endpoint detection and response (EDR) solutions can help detect anomalous file writes or code execution attempts. Once a patch is released, prompt application of updates is critical. Additionally, conducting regular security assessments and penetration testing focused on access control systems will help identify and remediate similar vulnerabilities proactively.
