## What is CVE-2024-20362?

CVE-2024-20362 is a medium-severity cross-site scripting vulnerability in Cisco Rv320 Firmware, published on 3 Apr 2024. 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 RV016, RV042, RV042G, RV082, RV320, and RV325 Routers could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.

 This vulnerability is due to insufficient input validation by the web-based management interface. An attacker could exploit this vulnerability by persuading a user to visit specific web pages that include malicious payloads. 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.

Weakness: CWE-80 (Improper Neutralization of Script-Related HTML Tags in a Web Page)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-20362 and fix it if it is affected.

What it is: CVE-2024-20362 is a medium-severity cross-site scripting vulnerability in Cisco Rv320 Firmware, published on 3 Apr 2024. 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-2024-20362 in the wild and no public exploit code.

Affected product: Cisco Rv320 Firmware. 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.
