# CVE-2011-1146: Missing authorization in n/a > Remote attackers with read-only access can cause host crashes or execute code via improper restriction of specific libvirt API calls. - **Severity:** Medium 6.9 (`AV:L/AC:M/Au:N/C:C/I:C/A:C`) - **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:** 15 Mar 2011 - **Updated:** 6 Aug 2024 - **Also known as:** DEBIAN-CVE-2011-1146, DSA-2194-1, GHSA-69mw-4jhr-4j3r, RHSA-2011:0391 ## What is CVE-2011-1146? CVE-2011-1146 is a medium-severity missing authorization vulnerability in Redhat Libvirt, published on 15 Mar 2011. Any signed-in user can exploit it over the network, with no action from the victim. ### Official description libvirt.c in the API in Red Hat libvirt 0.8.8 does not properly restrict operations in a read-only connection, which allows remote attackers to cause a denial of service (host OS crash) or possibly execute arbitrary code via a (1) virNodeDeviceDettach, (2) virNodeDeviceReset, (3) virDomainRevertToSnapshot, (4) virDomainSnapshotDelete, (5) virNodeDeviceReAttach, or (6) virConnectDomainXMLToNative call, a different vulnerability than CVE-2008-5086.

What it is: CVE-2011-1146 is a medium-severity missing authorization vulnerability in Redhat Libvirt, published on 15 Mar 2011. Any signed-in user can exploit it over the network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2011-1146 in the wild and no public exploit code. Affected product: Redhat Libvirt. 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.
