CVE-2019-19336 Cross-site scripting in ovirt-engine
Medium 5.4
Published
Updated
Check this codebase for CVE-2019-19336 and fix it if it is affected.
What it is: CVE-2019-19336 is a medium-severity cross-site scripting vulnerability in Redhat Virtualization, published on 19 Mar 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2019-19336 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.

What is CVE-2019-19336?
CVE-2019-19336 is a medium-severity cross-site scripting vulnerability in Redhat Virtualization, published on 19 Mar 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
A cross-site scripting vulnerability was reported in the oVirt-engine's OAuth authorization endpoint before version 4.3.8. URL parameters were included in the HTML response without escaping. This flaw would allow an attacker to craft malicious HTML pages that can run scripts in the context of the user's oVirt session.
