CVE-2017-14312: Nagios Core

High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Nagios Nagios Core: up to and including 4.3.4
