Summary
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.
Risk Assessment
An attacker can execute arbitrary JavaScript in the victim's browser and force logged-in users to perform unwanted state-changing operations, potentially leading to account takeover or configuration modification.
Recommendation
Upgrade Nagios XI to version 5.11.3 or later. Additionally, consider deploying SameSite cookie attributes to reduce CSRF risk.
Other vulnerabilities in Nagios XI
See all- CVE-2025-34284High
Nagios XI versions prior to 2024R2 contain a command injection vulnerability in the WinRM plugin. Insufficient validation of user-supplied parameters allows an authenticated administrator to inject shell metacharacters that are incorporated into backend command invocations. Successful exploitation enables arbitrary command execution with the privileges of the Nagios XI web application user.
- CVE-2024-14005High
Nagios XI versions prior to 2024R1.2 contain a command injection vulnerability in the Docker Wizard. Insufficient validation of user-supplied input in the wizard allows an authenticated administrator to inject shell metacharacters that are incorporated into backend command invocations. Successful exploitation enables arbitrary command execution with the privileges of the Nagios XI web application user.
- CVE-2024-14003Critical
Nagios XI versions prior to 2024R1.2 are vulnerable to remote code execution (RCE) through its NRDP server plugins. Insufficient validation of inbound NRDP request parameters allows crafted input to reach command execution paths, enabling attackers to execute arbitrary commands on the underlying host in the context of the web/Nagios service.
- CVE-2024-13999Critical
Nagios XI versions prior to 2024R1.1.3, under certain circumstances, disclose the server's Active Directory (AD) or LDAP authentication token to an authenticated user. Exposure of the server’s AD/LDAP token could allow domain-wide authentication misuse, escalation of privileges, or further compromise of network-integrated systems.
- CVE-2024-13996Critical
Nagios XI versions prior to 2024R1.1.3 did not invalidate all other active sessions for a user when that user's password was changed. As a result, any pre-existing sessions (including those potentially controlled by an attacker) remained valid after a credential update. This insufficient session expiration could allow continued unauthorized access to user data and actions even after a password change.
- CVE-2024-13994Critical
Nagios XI versions prior to 2024R1.1.2 have a missing authorization control when the 'Allow Insecure Logins' option is enabled. Under this configuration, any user can create valid login credentials for other users without proper authorization.
- CVE-2012-10063Critical
Nagios XI versions prior to 2012R1.3 contain a SQL injection vulnerability in the legacy Core Configuration Manager (CCM) interface. Authenticated users could manipulate SQL queries by supplying crafted input to specific CCM parameters, potentially allowing access to configuration data stored in the application database.
- CVE-2025-34227High
Nagios XI before 2026R1 is vulnerable to an authenticated command injection vulnerability within the MongoDB Database, MySQL Query, MySQL Server, Postgres Server, and Postgres Query wizards. It is possible to inject shell characters into arguments provided to the service and execute arbitrary system commands on the underlying host as the 'nagios' user.
- CVE-2023-40931Medium
A SQL injection vulnerability in Nagios XI versions 5.11.0 through 5.11.1 allows authenticated attackers to execute arbitrary SQL commands via the ID parameter in a POST request to /nagiosxi/admin/banner_message-ajaxhelper.php.
- CVE-2021-25299Medium
Nagios XI version xi-5.7.5 is affected by cross-site scripting (XSS) in /usr/local/nagiosxi/html/admin/sshterm.php due to improper input sanitization. A crafted URL can steal admin session cookies or be chained with other bugs for one-click RCE.
