Nagios Host esensors_websensor_configwizard_func Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Nagios Host. Authentication is required to exploit this vulnerability. The specific flaw exists within the esensors_websensor_configwizard_func method. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-28249.

CVE-2025-34288

Nagios XI versions prior to 2026R1.1 are vulnerable to local privilege escalation due to an unsafe interaction between sudo permissions and application file permissions. A user‑accessible maintenance script may be executed as root via sudo and includes an application file that is writable by a lower‑privileged user. A local attacker with access to the application account can modify this file to introduce malicious code, which is then executed with elevated privileges when the script is run. Successful exploitation results in arbitrary code execution as the root user.

CVE-2024-13998

Nagios XI versions prior to 2024R1.1.3, under certain circumstances, disclose sensitive user account information (including API keys and hashed passwords) to authenticated users who should not have access to that data. Exposure of API keys or password hashes could lead to account compromise, abuse of API privileges, or offline cracking attempts. CVE-2024-13995 addresses a similar vulnerability with a potentially incomplete fix for the underlying problem in earlier versions.

9.4 CVSS
CVE-2024-13997

Nagios XI versions prior to 2024R1.1.3 contain a privilege escalation vulnerability in which an authenticated administrator could leverage the Migrate Server feature to obtain root privileges on the underlying XI host. By abusing the migration workflow, an admin-level attacker could execute actions outside the intended security scope of the application, resulting in full control of the operating system.

5.1 CVSS
CVE-2021-47698

Nagios XI versions prior to 5.8.7 using embedded Nagios Core are vulnerable to cross-site scripting (XSS) via the Core UI’s Views URL handling (escape_string()). 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.

EPSS: 0.41%
5.1 CVSS
CVE-2024-13992

Nagios XI versions prior to < 2024R1.1 is vulnerable to a cross-site scripting (XSS) when a user visits the "missing page" (404) page after following a link from another website. The vulnerable component, page-missing.php, fails to properly validate or escape user-supplied input, allowing an attacker to craft a malicious link that, when visited by a victim, executes arbitrary JavaScript in the victim’s browser within the Nagios XI domain.
