CVE-2017-15114

As no additional authentication is configured this allows these services to connect to libvirtd (which is equivalent to root access).

HIGH 8.1EPSS 1.51%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.51%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

When libvirtd is configured by OSP director (tripleo-heat-templates) to use the TLS transport it defaults to the same certificate authority as all non-libvirtd services. As no additional authentication is configured this allows these services to connect to libvirtd (which is equivalent to root access). If a vulnerability exists in another service it could, combined with this flaw, be exploited to escalate privileges to gain control over compute nodes.
