Cross-site scripting (XSS) vulnerability in Nagios.

The general user interface in Nagios XI versions prior to 5.8.4 is vulnerable to authenticated reflected cross-site scripting. An authenticated victim, who accesses a specially crafted malicious URL, would unknowingly execute the attached payload.

Nagios XI version xi-5.7.5 is affected by cross-site scripting (XSS). The vulnerability exists in the file /usr/local/nagiosxi/html/admin/sshterm.php due to improper sanitization of user-controlled input. A maliciously crafted URL, when clicked by an admin user, can be used to steal his/her session cookies or it can be chained with the previous bugs to get one-click remote command execution (RCE) on the Nagios XI server.

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 XI versions prior to 5.11.3 are vulnerable to cross-site scripting (XSS) and cross-site request forgery (CSRF) via the Hypermap Replay component. An attacker can submit crafted input that is not properly validated or escaped, allowing injection of malicious script that executes in the context of a victim's browser (XSS). Additionally, the component does not enforce sufficient anti-CSRF protections on state-changing operations, enabling an attacker to induce authenticated users to perform unwanted actions.

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.

A stored cross-site scripting (XSS) vulnerability in the NOC component of Nagios XI version up to and including 2024R1 allows low-privileged users to execute malicious HTML or JavaScript code via the audio file upload functionality from the Operation Center section.

Nagios XI before 2024R1 was discovered to improperly handle API keys generation (randomly-generated), allowing attackers to possibly generate the same set of API keys for all users and utilize them to authenticate.

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.

An issue was discovered in Nagios XI 5.4.13. There is XSS exploitable via CSRF in (1) the Schedule New Report screen via the hour, minute, or ampm parameter, related to components/scheduledreporting; (2) includes/components/xicore/downtime.php, related to the update_pages function; (3) the ajaxhelper.php opts or background parameter; (4) the i[] array parameter to ajax_handler.php; or (5) the deploynotification.php title parameter.

Nagios XI 2024R1.2.2 is susceptible to a stored Cross-Site Scripting (XSS) vulnerability in the Tools page. This flaw allows an attacker to inject malicious scripts into the Tools interface, which are then stored and executed in the context of other users accessing the page.
