Summary

Nagios XI before 2026R1 is vulnerable to an authenticated command injection vulnerability within the MongoDB Database, MySQL Query, MySQL Server, Postgres Server, and Postgres Query wizards. It is possible to inject shell characters into arguments provided to the service and execute arbitrary system commands on the underlying host as the 'nagios' user.

Risk Assessment

An authenticated attacker can execute arbitrary system commands with nagios user privileges, potentially leading to host takeover and compromise of monitored infrastructure.

Recommendation

Update Nagios XI to version 2026R1 or later which includes the fix. Restrict access to wizards to trusted administrators only.
