CVE-2024-48891 is a vulnerability classified as an OS Command Injection (CWE-78) affecting Fortinet's FortiSOAR on-premise platform versions 7.3.0 through 7.6.1. The flaw stems from improper neutralization of special elements in operating system commands, which can be exploited by an attacker who already possesses a low-privileged, non-login shell on the affected system. By crafting specific commands, the attacker can escalate their privileges locally, potentially gaining administrative or root-level access. This escalation could allow the attacker to execute arbitrary commands with elevated privileges, compromising system confidentiality, integrity, and availability. The vulnerability requires prior local access with limited privileges, and the attack complexity is high due to the need for a specific environment and crafted commands. No public exploits or active exploitation have been reported to date. The vulnerability was reserved on October 9, 2024, and published on October 14, 2025. The CVSS v3.1 score is 6.6, indicating a medium severity level, with attack vector local (AV:L), attack complexity high (AC:H), privileges required low (PR:L), and no user interaction (UI:N). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Fortinet has not yet provided patch links, so mitigation currently relies on access control and monitoring.

The primary impact of CVE-2024-48891 is the potential for local privilege escalation on FortiSOAR on-premise deployments. An attacker who gains low-level shell access—possibly through other vulnerabilities or misconfigurations—can leverage this flaw to obtain higher privileges, including administrative rights. This elevated access can lead to full system compromise, allowing attackers to manipulate security orchestration workflows, access sensitive incident response data, disrupt security operations, or pivot to other parts of the network. Organizations relying on FortiSOAR for security automation and incident response could face significant operational disruption, data breaches, and loss of trust in their security infrastructure. The requirement for prior shell access limits the scope of exploitation but does not eliminate risk, especially in environments where initial access controls are weak or other vulnerabilities exist. The absence of known exploits in the wild reduces immediate risk but underscores the importance of proactive mitigation.

1. Restrict and monitor access to FortiSOAR systems, ensuring only authorized personnel have shell access. 2. Implement strict network segmentation and firewall rules to limit exposure of FortiSOAR servers. 3. Regularly audit and harden user accounts and permissions to minimize the chance of low-privileged shell access. 4. Employ host-based intrusion detection systems (HIDS) to detect unusual command execution or privilege escalation attempts. 5. Monitor logs for suspicious activity indicative of command injection or privilege escalation. 6. Apply the official patches from Fortinet promptly once they are released. 7. Conduct vulnerability assessments and penetration testing to identify and remediate any initial access vectors that could lead to low-privileged shell access. 8. Use multi-factor authentication and strong credential policies to reduce the risk of credential compromise. 9. Maintain up-to-date backups and incident response plans to recover quickly if compromise occurs.
