Description
Icinga 2 is an open source monitoring system. From 2.10.0 to before 2.15.1, 2.14.7, and 2.13.13, the safe-reload script (also used during systemctl reload icinga2) and logrotate configuration shipped with Icinga 2 read the PID of the main Icinga 2 process from a PID file writable by the daemon user, but send the signal as the root user. This can allow the Icinga user to send signals to processes it would otherwise not permitted to. A fix is included in the following Icinga 2 versions: 2.15.1, 2.14.7, and 2.13.13.

Can you explain this vulnerability to me?

This vulnerability in Icinga 2 involves the safe-reload script and logrotate configuration reading the PID of the main Icinga 2 process from a PID file that is writable by the daemon user. Because the signal to reload is sent as the root user, this allows the Icinga user to send signals to processes it normally would not have permission to, potentially leading to unauthorized control over system processes.


How can this vulnerability impact me? :

The vulnerability can allow the Icinga user to send signals to processes it is not normally permitted to control. This could lead to unauthorized actions on system processes, potentially causing disruption, privilege escalation, or other unintended behavior on the affected system.


What immediate steps should I take to mitigate this vulnerability?

Update Icinga 2 to version 2.15.1, 2.14.7, or 2.13.13 or later, as these versions include the fix for this vulnerability.
