## What is CVE-2024-20470?

CVE-2024-20470 is a medium-severity code injection vulnerability in Cisco Small Business RV Series Router Firmware, published on 2 Oct 2024. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

A vulnerability in the web-based management interface of Cisco Small Business RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers could allow an authenticated, remote attacker to execute arbitrary code on an affected device. In order to exploit this vulnerability, the attacker must have valid admin credentials.

This vulnerability exists because the web-based management interface does not sufficiently validate user-supplied input. An attacker could exploit this vulnerability by sending crafted HTTP input to an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system.

Weakness: CWE-146 (Improper Neutralization of Expression/Command Delimiters)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-20470 and fix it if it is affected.

What it is: CVE-2024-20470 is a medium-severity code injection vulnerability in Cisco Small Business RV Series Router Firmware, published on 2 Oct 2024. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-20470 in the wild and no public exploit code.

Affected product: Cisco Small Business RV Series Router 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.
