Description Adam Mariš 2017-09-12 11:48:45 UTC 
Nagios Core through 4.3.4 initially executes /usr/sbin/nagios as root but supports configuration options in which this file is owned by a non-root account (and similarly can have nagios.cfg owned by a non-root account), which allows local users to gain privileges by leveraging access to this non-root account.

Comment 1 Adam Mariš 2017-09-12 11:49:32 UTC

Comment 2 Jason Shepherd 2017-09-19 04:58:38 UTC 
In RHMAP both the /usr/sbin/nagios, and /etc/nagios/nagios.cfg  files are owned by root.

sh-4.2$ ls -la /etc/nagios/nagios.cfg 
-rwxrwxrwx. 1 root root 44259 Jun 16 00:13 /etc/nagios/nagios.cfg
sh-4.2$ ls -la /usr/sbin/nagios 
-rwxr-xr-x. 1 root root 713872 Jan 31  2017 /usr/sbin/nagios

Setting RHMAP as not affected.
