## What is CVE-2020-3365?

CVE-2020-3365 is a medium-severity path traversal vulnerability in Cisco Enterprise NFV Infrastructure Software, published on 4 Sep 2020. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

A vulnerability in the directory permissions of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, remote attacker to perform a directory traversal attack on a limited set of restricted directories. The vulnerability is due to a flaw in the logic that governs directory permissions. An attacker could exploit this vulnerability by using capabilities that are not controlled by the role-based access control (RBAC) mechanisms of the software. A successful exploit could allow the attacker to overwrite files on an affected device.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Check this codebase for CVE-2020-3365 and fix it if it is affected.

What it is: CVE-2020-3365 is a medium-severity path traversal vulnerability in Cisco Enterprise NFV Infrastructure Software, published on 4 Sep 2020. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2020-3365 in the wild and no public exploit code.

Affected product: Cisco Enterprise NFV Infrastructure 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.
