CVE-2019-15949
Nagios XI before 5.6.6 allows remote command execution as root. The exploit requires access to the server as the nagios user, or access as the admin user via the web interface. The getprofile.sh script, invoked by downloading a system profile (profile.php?cmd=download), is executed as root via a passwordless sudo entry; the script executes check_plugin, which is owned by the nagios user. A user logged into Nagios XI with permissions to modify plugins, or the nagios user on the server, can modify the check_plugin executable and insert malicious commands to execute as root.

Nagios XI 5.6.1 allows SQL injection via the username parameter to login.php?forgotpass (aka the reset password form). NOTE: The vendor disputes this issues as not being a vulnerability because the issue does not seem to be a legitimate SQL Injection. The POC does not show any valid injection that can be done with the variable provided, and while the username value being passed does get used in a SQL query, it is passed through SQL escaping functions when creating the call. The vendor tried re-creating the issue with no luck
