CVE-2025-34286 is a high-severity remote code execution vulnerability affecting Nagios XI versions prior to 2026R1. An authenticated administrator can exploit insufficient parameter validation in the Core Config Manager's "Run Check" command to inject shell metacharacters, leading to arbitrary command execution with the privileges of the web application user. This could allow an attacker to gain full control of the underlying host operating system. While no active exploitation, public exploit code, or significant community discussion has been observed, the vulnerability carries a CVSS score of 7.2 and a FAUCET Risk Score of 71/100.
