Summary
Fortinet FortiNAC versions below 7.2.1, below 9.4.3, below 9.2.8, and all earlier versions of 8.x are vulnerable to deserialization of untrusted data. An attacker can execute unauthorized code or commands via specifically crafted requests on the inter-server communication port.
Risk Assessment
This vulnerability could lead to serious security breaches, allowing attackers to remotely execute code on the system. Organizations should be aware of the risks associated with unauthorized access to their infrastructure.
Recommendation
It is recommended to upgrade FortiNAC to versions 7.2.1, 9.4.3, or 9.2.8 to mitigate the risk associated with this vulnerability. For 8.x versions that will not be fixed, consider migrating to a supported version.
