Security readout for executives and security teams

This issue affects Nagios Core through 4.3.4 when ownership and configuration allow non-root accounts to control files that Nagios initially runs as root. A local user with access to that account could turn that control into higher privileges. It is not described as remotely exploitable in the supplied sources. Exposure is most likely on self-managed Nagios Core deployments through 4.3.4 with non-root ownership or write access over the Nagios binary or nagios.cfg. Treat this as a targeted internal privilege risk, not an internet-scale emergency based on the supplied evidence. Prioritize shared, multi-user, or externally administered Nagios servers because successful abuse could produce root-level control. Mitigation focus: Check Nagios and operating-system vendor guidance for supported fixed versions.; Upgrade Nagios Core if vendor guidance identifies a fixed release.; Restrict ownership of /usr/sbin/nagios and nagios.cfg to trusted administrative users..
