CVE-2008-5027: The Nagios process in (1) Nagios before 3.0.5 and (2) op5 Monitor before 4.0.1 allows remote authenticated...

Security readout for executives and security teams

This issue affects older Nagios and op5 Monitor deployments. An authenticated remote user could bypass intended authorization controls and cause the monitoring process to run arbitrary programs. Because monitoring systems often have privileged operational access, compromise could affect infrastructure visibility and connected automation. Exposure is most likely in legacy Nagios 3.x installations before 3.0.5 or op5 Monitor before 4.0.1, especially where authenticated users can access monitoring functions. Internet exposure is not required; internal authenticated users are in scope. Treat as high priority for legacy monitoring environments. The issue requires authentication, but successful abuse could turn a monitoring account into code execution by the monitoring process, creating operational and security risk. Mitigation focus: Upgrade Nagios to 3.0.5 or later where applicable.; Upgrade op5 Monitor to 4.0.1 or later where applicable.; Apply vendor distribution updates from Ubuntu, Gentoo, or relevant package maintainers..
