CVE-2024-54024 is an OS command injection vulnerability identified in Fortinet's FortiIsolator product, specifically affecting versions prior to 2.4.6, including 2.4.3. The vulnerability arises from improper neutralization of special elements in OS commands (CWE-78), allowing a privileged attacker with super-admin profile and command-line interface (CLI) access to execute arbitrary code on the underlying operating system. The attack vector involves sending specially crafted HTTP requests that exploit this improper input handling. Since the attacker must already have super-admin privileges and CLI access, the vulnerability is an escalation of privilege rather than an initial access vector. The CVSS v3.1 base score is 7.0, indicating high severity, with metrics reflecting network attack vector (AV:N), low attack complexity (AC:L), high privileges required (PR:H), no user interaction (UI:N), and full impact on confidentiality, integrity, and availability (C:H/I:H/A:H). The exploitability is functional (E:F), and the report confidence is confirmed (RC:C). There are no known exploits in the wild at the time of publication. FortiIsolator is a security product designed to isolate web browsing sessions to prevent malware infections and data leakage. This vulnerability could allow an attacker to bypass isolation controls, execute arbitrary commands, and potentially compromise the host system, undermining the product's security guarantees. The vulnerability was reserved on 2024-11-27 and published on 2025-04-08. No official patch links are provided in the data, but upgrading to version 2.4.6 or later is implied as the fix.

The impact of CVE-2024-54024 is significant for organizations deploying FortiIsolator as part of their web isolation and endpoint security strategy. Successful exploitation allows a privileged attacker to execute arbitrary OS commands, potentially leading to full system compromise. This can result in unauthorized data access, manipulation, or destruction, disruption of services, and lateral movement within the network. Since the vulnerability requires super-admin CLI access, the initial compromise barrier is high; however, once exploited, the attacker gains powerful control over the system. This could undermine the security posture of critical infrastructure, financial institutions, government agencies, and enterprises relying on FortiIsolator for threat containment. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially if attackers develop exploits post-disclosure. The vulnerability could also be leveraged in targeted attacks or insider threat scenarios. Organizations failing to patch may face increased risk of data breaches, operational disruption, and reputational damage.

1. Upgrade FortiIsolator to version 2.4.6 or later immediately upon availability to apply the official fix. 2. Restrict CLI access strictly to trusted administrators and implement multi-factor authentication to reduce the risk of privileged credential compromise. 3. Monitor and audit CLI access logs for unusual or unauthorized activity to detect potential exploitation attempts early. 4. Employ network segmentation to isolate FortiIsolator management interfaces from general user networks and the internet. 5. Implement strict input validation and filtering on HTTP requests at the network perimeter to detect and block suspicious payloads targeting FortiIsolator. 6. Conduct regular vulnerability assessments and penetration testing focused on privileged access controls and command injection vectors. 7. Educate administrators on secure management practices and the risks associated with super-admin privileges. 8. Maintain up-to-date incident response plans that include scenarios involving FortiIsolator compromise.
