CVE-2025-34284

Severity CVSS v4.0:
CRITICAL
Type:
CWE-78 OS Command Injections
Publication date:
30/10/2025
Last modified:
06/11/2025

Description

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 and can be leveraged to modify configuration, exfiltrate data, disrupt monitoring operations, or execute commands on the underlying host operating system.
