## What is CVE-2020-14145?

CVE-2020-14145 is a medium-severity vulnerability in Netapp Active Iq Unified Manager, published on 29 Jun 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected.

Weakness: CWE-203 (Observable Discrepancy)

Check this codebase for CVE-2020-14145 and fix it if it is affected.

What it is: CVE-2020-14145 is a medium-severity vulnerability in Netapp Active Iq Unified Manager, published on 29 Jun 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-2020-14145 in the wild and no public exploit code.

Affected product: Netapp Active Iq Unified 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.
