## What is CVE-2021-34733?

CVE-2021-34733 is a medium-severity vulnerability in Cisco Evolved Programmable Network Manager, published on 2 Sep 2021. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A vulnerability in the CLI of Cisco Prime Infrastructure and Cisco Evolved Programmable Network (EPN) Manager could allow an authenticated, local attacker to access sensitive information stored on the underlying file system of an affected system. This vulnerability exists because sensitive information is not sufficiently secured when it is stored. An attacker could exploit this vulnerability by gaining unauthorized access to sensitive information on an affected system. A successful exploit could allow the attacker to create forged authentication requests and gain unauthorized access to the affected system.

Weakness: CWE-522 (Insufficiently Protected Credentials)

```text
Check this codebase for CVE-2021-34733 and fix it if it is affected.

What it is: CVE-2021-34733 is a medium-severity vulnerability in Cisco Evolved Programmable Network Manager, published on 2 Sep 2021. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2021-34733 in the wild and no public exploit code.

Affected product: Cisco Evolved Programmable 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.
