# CVE-2019-3879: Missing authorization in ovirt-engine > Low-privilege users can delete virtual machine disks due to skipped permission checks in the oVirt REST API. - **Severity:** Medium 6.5 (`CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 25 Mar 2019 - **Updated:** 4 Aug 2024 - **Also known as:** GHSA-9fjf-3vjh-p57c, RHBA-2019:0802 ## What is CVE-2019-3879? CVE-2019-3879 is a medium-severity missing authorization vulnerability in Redhat Virtualization, published on 25 Mar 2019. Any signed-in user can exploit it over the network, with no action from the victim. ### Official description It was discovered that in the ovirt's REST API before version 4.3.2.1, RemoveDiskCommand is triggered as an internal command, meaning the permission validation that should be performed against the calling user is skipped. A user with low privileges (eg Basic Operations) could exploit this flaw to delete disks attached to guests. Weakness: CWE-862 (Missing Authorization) ## Which versions are affected by CVE-2019-3879?

What it is: CVE-2019-3879 is a medium-severity missing authorization vulnerability in Redhat Virtualization, published on 25 Mar 2019. Any signed-in user can exploit it over the network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2019-3879 in the wild and no public exploit code. Affected product: Redhat Virtualization. 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.
