## What is CVE-2020-3586?

CVE-2020-3586 is a critical command injection vulnerability in Cisco DNA Spaces Connector, published on 18 Nov 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A vulnerability in the web-based management interface of Cisco DNA Spaces Connector could allow an unauthenticated, remote attacker to execute arbitrary commands on an affected device. The vulnerability is due to insufficient validation of user-supplied input in the web-based management interface.

Check this codebase for CVE-2020-3586 and fix it if it is affected.

What it is: CVE-2020-3586 is a critical command injection vulnerability in Cisco DNA Spaces Connector, published on 18 Nov 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2020-3586 in the wild and no public exploit code.

Affected product: Cisco DNA Spaces Connector. 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.
