Security readout for executives and security teams
CVE-2021-25296 lets an authenticated Nagios XI user inject operating system commands into the Nagios XI server through the Windows WMI configuration wizard. Because Nagios often monitors sensitive infrastructure, compromise could expose credentials, monitoring data, and the server itself. Exposure is most likely in Nagios XI 5.7.5 instances where authenticated users can access the Windows WMI configuration wizard. The bundle does not provide a broader affected-version range. Treat this as urgent for any exposed Nagios XI 5.7.5 system because CISA lists exploitation in the wild and successful abuse can compromise the monitoring server with high confidentiality, integrity, and availability impact. Mitigation focus: Identify and prioritize Nagios XI 5.7.5 deployments.; Review Nagios version guidance and upgrade to a vendor-supported fixed release.; Restrict Nagios XI access to trusted administrative networks..
