CVE-2024-1367 is a high-severity OS command injection vulnerability identified in Tenable Security Center, a widely used vulnerability management and security analytics platform. The vulnerability arises due to improper neutralization of special elements in OS commands (CWE-78), specifically when an authenticated remote attacker with administrator privileges modifies Logging parameters within the Security Center application. This flaw allows the attacker to inject arbitrary OS commands that the underlying system executes with the privileges of the Security Center host process. Since the attacker must have administrator-level access to the application, the vulnerability is not exploitable by unauthenticated users or those with lower privileges. However, once exploited, it can lead to full compromise of the host system, enabling arbitrary code execution, data exfiltration, disruption of services, or pivoting to other network assets. The CVSS v3.1 base score is 7.2, reflecting high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, and no user interaction required. No known exploits are currently reported in the wild, but the presence of this vulnerability in a critical security management tool makes it a high-value target for attackers. The affected versions are not explicitly enumerated beyond "0," suggesting the need for organizations to verify their specific deployments against vendor advisories. The lack of available patches at the time of publication underscores the urgency for mitigation and monitoring.

For European organizations, the impact of CVE-2024-1367 can be significant due to the critical role Tenable Security Center plays in vulnerability management and security monitoring. Successful exploitation could allow attackers to gain control over the Security Center host, undermining the integrity and reliability of security data and potentially disabling or manipulating vulnerability scans and alerts. This compromises the organization's ability to detect and respond to other threats, increasing the risk of broader network intrusions. Confidential data stored or processed by the Security Center could be exposed or altered, violating data protection regulations such as GDPR. Additionally, availability impacts could disrupt security operations, delaying incident response. Given the high privileges required, insider threats or attackers who have already compromised administrative credentials pose the greatest risk. The disruption of a central security tool could cascade into wider operational and reputational damage, especially for critical infrastructure, financial institutions, and large enterprises prevalent in Europe.

1. Immediate verification of Tenable Security Center versions deployed within the organization against vendor advisories and applying any available patches or updates as soon as they are released. 2. Restrict and monitor administrator access to the Security Center application, enforcing the principle of least privilege and using multi-factor authentication to reduce the risk of credential compromise. 3. Implement strict input validation and sanitization controls on all user inputs related to logging and configuration parameters, if custom integrations or scripts are used. 4. Monitor Security Center logs and system behavior for unusual activities indicative of command injection attempts or unauthorized configuration changes. 5. Segment the Security Center host within the network to limit lateral movement in case of compromise. 6. Conduct regular security audits and penetration testing focused on administrative interfaces. 7. Prepare incident response plans specifically addressing potential compromise of security management tools. 8. Consider temporary compensating controls such as disabling remote administration or restricting access to trusted IP addresses until patches are applied.
