Nagios Fusion < 4.2.0 Email Settings Stored XSS via SMTP/sendmail

Nagios Fusion versions prior to 4.2.0 contain a stored cross-site scripting (XSS) vulnerability when adding or configuring Email Settings. 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 or modify SMTP/email settings or manipulate the sendmail configuration fields could persist a malicious payload that executes in the context of other users' browsers.

Nagios Fusion < 4.2.0 LDAP/AD Integration Stored XSS

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 that executes in the context of other users' browsers.

Nagios Fusion < 4.2.0 License Information Reflected XSS

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 by the reflected XSS, the resulting browser compromise can lead to credential/session theft and unauthorized administrative actions.

Nagios Fusion < 4.1.5 XSS via fusionwindow Parameter

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.

Nagios Fusion < 4.0.1 XSS via Users/Servers Page

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.

This CVE ID has been rejected or withdrawn by its CVE Numbering Authority as it is a duplicate of CVE-2025-60424.

This CVE ID has been rejected or withdrawn by its CVE Numbering Authority as it is a duplicate of CVE-2025-60425.

A lack of rate limiting in the OTP verification component of Nagios Fusion v2024R1.2 and v2024R2 allows attackers to bypass authentication via a bruteforce attack.

Nagios Fusion v2024R1.2 and v2024R2 does not invalidate already existing session tokens when the two-factor authentication mechanism is enabled, allowing attackers to perform a session hijacking attack.

Incorrect Access Control in Nagios Fusion 4.1.8 and earlier allows low-privileged authenticated users to extract passwords used to manage fused servers via the test_server command in ajaxhelper.php.

Incorrect File Permissions in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation to root via modification of scripts. Low-privileges users are able to modify files that can be executed by sudo.

Command Injection in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation to nagios.

Incorrect SSL certificate validation in Nagios Fusion 4.1.8 and earlier allows for Escalation of Privileges or Code Execution as root via vectors related to download of an untrusted update package in upgrade_to_latest.sh.

Incorrect File Permissions in Nagios XI 5.7.5 and earlier and Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation to root. Low-privileged users are able to modify files that are included (aka sourced) by scripts executed by root.

Improper Input Validation in Nagios Fusion 4.1.8 and earlier allows an authenticated attacker to execute remote code via table pagination.

Execution with Unnecessary Privileges in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation as nagios via installation of a malicious component containing PHP code.

Improper input validation in Nagios Fusion 4.1.8 and earlier allows a remote attacker with control over a fused server to inject arbitrary HTML, aka XSS.

Command Injection in Nagios Fusion 4.1.8 and earlier allows Privilege Escalation from apache to root in cmd_subsys.php.

Command Injection in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation or Code Execution as root via vectors related to corrupt component installation in cmd_subsys.php.

Insufficient Verification of Data Authenticity in Nagios Fusion 4.1.8 and earlier and Nagios XI 5.7.5 and earlier allows for Escalation of Privileges or Code Execution as root via vectors related to an untrusted update package to upgrade_to_latest.sh.
