Descriptions

An issue was discovered in Icinga2 before v2.12.0-rc1. The prepare-dirs script (run as part of the icinga2 systemd service) executes chmod 2750 /run/icinga2/cmd. /run/icinga2 is under control of an unprivileged user by default. If /run/icinga2/cmd is a symlink, then it will by followed and arbitrary files can be changed to mode 2750 by the unprivileged icinga2 user.

Se detectó un problema en Icinga2 versiones anteriores a v2.12.0-rc1. El script prepare-dirs (ejecutado como parte del servicio icinga2 systemd) ejecuta chmod 2750 /run/icinga2/cmd. /run/icinga2 está bajo el control de un usuario no privilegiado por defecto. Si /run/icinga2/cmd es un enlace simbólico, entonces será seguido y los archivos arbitrarios pueden ser cambiados al modo 2750 por el usuario icinga2 no privilegiado
