## What is CVE-2023-20204?

CVE-2023-20204 is a medium-severity cross-site scripting vulnerability in Cisco BroadWorks, published on 3 Aug 2023. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

A vulnerability in the web-based management interface of Cisco BroadWorks CommPilot Application Software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.

 This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

Check this codebase for CVE-2023-20204 and fix it if it is affected.

What it is: CVE-2023-20204 is a medium-severity cross-site scripting vulnerability in Cisco BroadWorks, published on 3 Aug 2023. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2023-20204 in the wild and no public exploit code.

Affected product: Cisco BroadWorks. 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.
