## What is CVE-2018-0465?

CVE-2018-0465 is a medium-severity cross-site scripting vulnerability in Cisco Small Business 300 Series Managed Switches, published on 5 Oct 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-based management interface of Cisco Small Business 300 Series Managed Switches could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface of an affected system. The vulnerability exists because the affected management interface performs insufficient validation of user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or allow the attacker to access sensitive, browser-based information.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Check this codebase for CVE-2018-0465 and fix it if it is affected.

What it is: CVE-2018-0465 is a medium-severity cross-site scripting vulnerability in Cisco Small Business 300 Series Managed Switches, published on 5 Oct 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-2018-0465 in the wild and no public exploit code.

Affected product: Cisco Small Business 300 Series Managed Switches. 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.
