CVE-2023-30797
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNetflix Lemur before version 1.3.2 used insufficiently random values when generating default credentials. The insufficiently random values may allow an attacker to guess the credentials and gain access to resources managed by Lemur.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve · scoped1.3.2
1.3.2
- 1. Back up your current Lemur installation and database before upgrading.
- 2. Identify your current Lemur version by checking the installed package or running `lemur --version` if available.
- 3. Upgrade Lemur to version 1.3.2 or later using your package manager: `pip install lemur==1.3.2` or by updating your requirements file.
- 4. If using Docker, pull the updated image with the tag corresponding to version 1.3.2.
- 5. After upgrading, verify the new version is installed: `pip show lemur` or check the running application.
- 6. Review any default credentials that were generated before the upgrade and regenerate them using the fixed version's credential generation mechanism.
- 7. Test that authentication and access to managed resources still work correctly.
- 8. Monitor logs for any suspicious access attempts that may have occurred using guessed credentials.
