CVE-2024-52961 is a command injection vulnerability identified in Fortinet FortiSandbox, a security product used for advanced threat detection through sandboxing. The vulnerability arises due to improper neutralization of special elements in OS commands (CWE-78), allowing an authenticated attacker with at least read-only permissions to execute arbitrary OS commands by sending specially crafted requests to the FortiSandbox management interface. This flaw affects multiple FortiSandbox versions, including 3.0.0, 3.1.x, 3.2.x, 4.0.x, 4.2.x, 4.4.x, and 5.0.0. The vulnerability does not require user interaction but does require authentication with at least read-only privileges, which may be obtained through credential compromise or insider threat. The CVSS v3.1 score of 8.6 indicates a high-severity issue with network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. Exploiting this vulnerability could allow attackers to execute arbitrary commands on the underlying operating system, potentially leading to full system compromise, data exfiltration, or disruption of sandboxing services. No public exploits or active exploitation have been reported yet, but the presence of this vulnerability in a critical security appliance makes it a significant risk. Fortinet has not yet published patches or mitigation details at the time of this report, emphasizing the need for immediate risk management and monitoring.

For European organizations, the impact of CVE-2024-52961 could be severe. FortiSandbox is widely deployed in enterprises and critical infrastructure sectors for malware analysis and threat detection. Successful exploitation could lead to unauthorized command execution on the sandbox appliance, compromising the integrity and availability of threat detection capabilities. This could allow attackers to evade detection, persist within networks, or pivot to other systems. Confidential data processed or stored by FortiSandbox could be exposed or altered. Disruption of sandbox services could delay incident response and increase exposure to malware outbreaks. Given the high CVSS score and the critical role of FortiSandbox, affected organizations could face operational downtime, regulatory compliance issues (e.g., GDPR), and reputational damage. The requirement for authentication reduces the attack surface but does not eliminate risk, especially in environments with weak credential management or insider threats.

1. Immediately restrict access to FortiSandbox management interfaces to trusted administrators via network segmentation, VPNs, or IP whitelisting. 2. Enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce risk of credential compromise. 3. Monitor FortiSandbox logs and network traffic for unusual command execution patterns or unauthorized access attempts. 4. Apply vendor patches and updates as soon as they become available; maintain close communication with Fortinet for patch release notifications. 5. Conduct regular audits of user permissions to ensure no unnecessary read or higher privileges are granted. 6. Implement intrusion detection systems (IDS) and endpoint detection and response (EDR) tools to detect lateral movement or exploitation attempts. 7. Prepare incident response plans specific to FortiSandbox compromise scenarios. 8. Consider temporary disabling or isolating vulnerable FortiSandbox instances if patching is delayed and risk is high.
