## What is CVE-2018-0388?

CVE-2018-0388 is a medium-severity cross-site scripting vulnerability in Cisco Wireless Lan Controller Software, published on 17 Oct 2018. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.

### Official description

A vulnerability in the web-based interface of Cisco Wireless LAN Controller (WLC) Software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against the user of the web-based interface of an affected system. The vulnerability is due to insufficient validation of user-supplied input by the web-based interface. 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 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-2018-0388 and fix it if it is affected.

What it is: CVE-2018-0388 is a medium-severity cross-site scripting vulnerability in Cisco Wireless Lan Controller Software, published on 17 Oct 2018. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2018-0388 in the wild and no public exploit code.

Affected product: Cisco Wireless Lan Controller Software. 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.
