Description Robert Frohl 2021-07-16 06:56:57 UTC

Icinga is a monitoring system which checks the availability of network
resources, notifies users of outages, and generates performance data for
reporting. From version 2.4.0 through version 2.12.4, a vulnerability exists
that may allow privilege escalation for authenticated API users. With a read-ony
user's credentials, an attacker can view most attributes of all config objects
including `ticket_salt` of `ApiListener`. This salt is enough to compute a
ticket for every possible common name (CN). A ticket, the master node's
certificate, and a self-signed certificate are enough to successfully request
the desired certificate from Icinga. That certificate may in turn be used to
steal an endpoint or API user's identity. Versions 2.12.5 and 2.11.10 both
contain a fix the vulnerability. As a workaround, one may either specify
queryable types explicitly or filter out ApiListener objects.
