Summary
Nagios Fusion versions prior to 4.2.0 contain a stored cross-site scripting (XSS) vulnerability in the LDAP/AD authentication-server configuration. Unsanitized user input can be stored and later rendered in the administrative UI, causing JavaScript to execute in the browser of any user who views the affected page. An attacker who can add authentication servers via LDAP/AD integration could persist a malicious payload.
Risk Assessment
The vulnerability allows an attacker to execute arbitrary JavaScript in the context of other users' browsers, potentially leading to session or credential theft. The risk is high in environments with LDAP/AD integration.
Recommendation
Update Nagios Fusion to version 4.2.0 or later. It is also recommended to verify LDAP/AD server configurations for unauthorized changes.

- CVE-2023-53689Medium
Nagios Fusion versions prior to 4.2.0 contain a reflected cross-site scripting (XSS) vulnerability in the license key configuration flow that can result in execution of attacker-controlled script in the browser of a user who follows a crafted URL. While the application server itself is not directly corrupted, the resulting browser compromise can lead to credential/session theft and unauthorized administrative actions.
- CVE-2018-25119Medium
Nagios Fusion versions prior to 4.1.5 are vulnerable to cross-site scripting (XSS) via the "fusionwindow" parameter. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.
- CVE-2017-20209Medium
Nagios Fusion versions prior to 4.0.1 are vulnerable to cross-site scripting (XSS) via the Users and Servers pages. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.
