AI-suggested
To mitigate CVE-2025-47857, organizations should prioritize upgrading FortiWeb devices to versions later than 7.6.3 or 7.4.8 once patches are available. Until patches are released, restrict CLI access strictly to trusted administrators and enforce strong authentication and authorization controls to limit privileged access. Implement network segmentation to isolate management interfaces of FortiWeb devices from general user networks and the internet. Monitor CLI command logs for unusual or unauthorized commands indicative of exploitation attempts. Employ multi-factor authentication for administrative access to reduce risk of credential compromise. Conduct regular audits of privileged accounts and remove unnecessary privileges. Additionally, consider deploying intrusion detection systems to identify anomalous command execution patterns. Maintain up-to-date backups of device configurations to enable rapid recovery if compromise occurs. Finally, stay informed through Fortinet advisories and threat intelligence feeds for updates on patches and exploitation activity.
Description
A improper neutralization of special elements used in an os command ('os command injection') vulnerability [CWE-78] in Fortinet FortiWeb CLI version 7.6.0 through 7.6.3 and before 7.4.8 allows a privileged attacker to execute arbitrary code or command via crafted CLI commands.
