## What is CVE-2018-0326?

CVE-2018-0326 is a medium-severity cross-site scripting vulnerability in Cisco TelePresence Server, published on 17 May 2018. 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 vulnerability in the web UI of Cisco TelePresence Server Software could allow an unauthenticated, remote attacker to conduct a cross-frame scripting (XFS) attack against a user of the web UI of the affected software. The vulnerability is due to insufficient protections for HTML inline frames (iframes) by the web UI of the affected software. An attacker could exploit this vulnerability by persuading a user of the affected UI to navigate to an attacker-controlled web page that contains a malicious HTML iframe. A successful exploit could allow the attacker to conduct click-jacking or other client-side browser attacks on the affected system. Cisco Bug IDs: CSCun79565.

Weakness: CWE-693 (Protection Mechanism Failure)

What it is: CVE-2018-0326 is a medium-severity cross-site scripting vulnerability in Cisco TelePresence Server, published on 17 May 2018. 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-2018-0326 in the wild and no public exploit code.

Affected product: Cisco TelePresence Server. 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.
