Description Preview
A command injection vulnerability (CWE-77) exists in Fortinet FortiNAC versions 7.2.1 and earlier, and 9.4.3 and earlier. This vulnerability allows an attacker to gain limited, unauthorized file access by sending specifically crafted requests to the inter-server communication port. The issue stems from improper neutralization of special elements used in command execution, which can be exploited to inject malicious commands.
Overview
Fortinet FortiNAC is a network access control solution that provides visibility, control, and automated response for everything connected to the network. The identified vulnerability (CVE-2023-33300) is a command injection flaw that affects the inter-server communication functionality. An attacker who can reach the affected port can craft specific requests that exploit improper input validation to gain unauthorized access to files on the system. This vulnerability is particularly concerning in network security products as they often contain sensitive information and have privileged access to network resources.
Remediation
To address this vulnerability, organizations should:
- Update FortiNAC to versions newer than 7.2.1 or 9.4.3, as appropriate for your deployment path
- Ensure that the inter-server communication port is not exposed to untrusted networks
- Implement network segmentation to restrict access to management interfaces
- Monitor system logs for unusual file access patterns or communication attempts
- Follow Fortinet's security best practices for FortiNAC deployment
- Apply the patches provided by Fortinet as detailed in their security advisory FG-IR-23-096
