Exploits Discovered - Published CVE-2017-16882
Title: Icinga core root privilege escalation via insecure permissions
Author: Michael Orlitzky
Fixedin: commits ad2eb58 and 161c621, version 1.14.2
Icinga installs two sets of files with insecure permissions: after installation, the executables and the configuration files are all owned by the same unprivileged user and group (typically, icinga) that the daemon runs as. In one attack, the unprivileged user simply replaces the icinga executable with one that does his bidding. A slightly more complicated attack can be mounted by the unprivileged user by scheduling a malicious service check and then altering icinga.cfg to execute that check as root.
