Fortinet FortiNAC Panel Detection Scanner

Fortinet FortiNAC is a network access control solution widely used by organizations to secure their networks by managing and controlling devices connecting to the network. It is often deployed by IT departments in enterprises, educational institutions, and government bodies to ensure that only authorized devices can access the network. FortiNAC helps in reducing the risk of security breaches by visibility into all connected equipment and automatically responding to unauthorized access. It assists network administrators in enforcing security policies effectively. The software is known for its scalability, allowing it to be used in both small networks and large-scale implementations. By overseeing network activity and access, FortiNAC provides comprehensive network security and operational efficiency.

The panel detection vulnerability in Fortinet FortiNAC relates to its login interface, which can be identified by unauthorized parties. Understanding whether FortiNAC is in use within a digital environment lets attackers potentially tailor subsequent attacks targeting known issues of the solution. While merely detecting a panel is not directly harmful, it exposes the existence of FortiNAC, increasing any subsequent risks associated with misconfigurations or unpatched vulnerabilities. Identifying login panels is an initial step for threat actors in gathering intelligence about deployed technologies. This form of detection relies on specific response patterns or unique markers typical of FortiNAC interfaces. Once found, the knowledge of FortiNAC's presence can inform attackers' strategy to find more significant weaknesses or entry points.

Technically, this vulnerability is identified by sending requests to known FortiNAC endpoints and examining the responses for specific keywords or structures typical to FortiNAC panels, such as the presence of "FortiNAC" in response bodies or recognizable HTTP headers. The GET request to a welcome action page confirms the existence of FortiNAC based on the incidence of keywords, response structures, or status codes. For example, deciphering the login page through particular response content or URL paths featuring 'WelcomeActions.jsp' can pinpoint the FortiNAC Login Panel presence. The matchers detailed in the request analyze both response body words and HTTP status to ensure accurate detection without false positives.

If exploited by malicious entities, the presence of the FortiNAC panel allows attackers to attempt a variety of cyber attacks, ranging from Denial of Service (DoS) to sophisticated credential harvesting or brute force attempts. Although the panel detection itself is not indicative of a deeper vulnerability, it signifies an initial reconnaissance success, potentially paving the way for future threats. Attackers might employ spear phishing or try default credentials as aware of the specific technology stack running in an environment. The insights gained can reveal network configuration settings or leverage undocumented features, which if not secured properly, lead to unauthorized access or data breaches.
