## What is CVE-2024-20432?

CVE-2024-20432 is a critical command injection vulnerability in Cisco Data Center Network Manager, published on 2 Oct 2024. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

A vulnerability in the REST API and web UI of Cisco Nexus Dashboard Fabric Controller (NDFC) could allow an authenticated, low-privileged, remote attacker to perform a command injection attack against an affected device.
 
This vulnerability is due to improper user authorization and insufficient validation of command arguments. An attacker could exploit this vulnerability by submitting crafted commands to an affected REST API endpoint or through the web UI. A successful exploit could allow the attacker to execute arbitrary commands on the CLI of a Cisco NDFC-managed device with network-admin privileges.
 
Note: This vulnerability does not affect Cisco NDFC when it is configured for storage area network (SAN) controller deployment.

Weakness: CWE-77 (Improper Neutralization of Special Elements used in a Command)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-20432 and fix it if it is affected.

What it is: CVE-2024-20432 is a critical command injection vulnerability in Cisco Data Center Network Manager, published on 2 Oct 2024. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-20432 in the wild and no public exploit code.

Affected product: Cisco Data Center Network Manager. 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.
