CVE-2019-15949 Information

Description

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.
