CVE-2017-15114

High
Published: Translated: NVD NIST

Summary

A vulnerability in libvirtd when configured by OSP director to use TLS transport defaults to the same certificate authority as other services. The lack of additional authentication allows these services to connect to libvirtd, which is equivalent to root access.

Risk Assessment

The risk to the organization is that if another service has a vulnerability, it could be exploited in conjunction with this flaw to escalate privileges and gain control over compute nodes.

Recommendation

It is recommended to configure additional authentication for libvirtd and use a separate certificate authority for services to minimize the risk of unauthorized access.

Original NVD description (English source)

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.
