CVE-2012-2693 Missing authorization in n/a
Low 3.7
Published
Updated
Check this codebase for CVE-2012-2693 and fix it if it is affected.
What it is: CVE-2012-2693 is a low-severity missing authorization vulnerability in Redhat Libvirt, published on 17 Jun 2012. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2012-2693 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.

What is CVE-2012-2693?
CVE-2012-2693 is a low-severity missing authorization vulnerability in Redhat Libvirt, published on 17 Jun 2012. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
libvirt, possibly before 0.9.12, does not properly assign USB devices to virtual machines when multiple devices have the same vendor and product ID, which might cause the wrong device to be associated with a guest and might allow local users to access unintended USB devices.
