## What is CVE-2001-1585?

CVE-2001-1585 is a medium-severity authentication bypass vulnerability in OpenSSH, published on 6 Oct 2007. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

SSH protocol 2 (aka SSH-2) public key authentication in the development snapshot of OpenSSH 2.3.1, available from 2001-01-18 through 2001-02-08, does not perform a challenge-response step to ensure that the client has the proper private key, which allows remote attackers to bypass authentication as other users by supplying a public key from that user's authorized_keys file.

Weakness: CWE-287 (Improper Authentication)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2001-1585 and fix it if it is affected.

What it is: CVE-2001-1585 is a medium-severity authentication bypass vulnerability in OpenSSH, published on 6 Oct 2007. 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-2001-1585 in the wild and no public exploit code.

Affected product: OpenSSH. 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.
