# CVE-2017-15114: Missing authorization in n/a

> Misconfigured TLS in libvirtd allows other services to connect without additional authentication, enabling privilege escalation to root on compute nodes.

- **Severity:** High 8.1 (`CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H`)
- **Exploited in the wild:** Not known
- **Login needed:** Not needed
- **Attackable:** Over the internet
- **Victim action needed:** Not needed
- **Fix available:** No
- **Published:** 27 Nov 2017
- **Updated:** 5 Aug 2024

## What is CVE-2017-15114?

CVE-2017-15114 is a high-severity missing authorization vulnerability in n/a, published on 27 Nov 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official 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.

Weakness: CWE-295 (Improper Certificate Validation)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2017-15114 and fix it if it is affected.

What it is: CVE-2017-15114 is a high-severity missing authorization vulnerability in n/a, published on 27 Nov 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-15114 in the wild and no public exploit code.

Affected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
