Note: Verify declared build manifests and deployed runtime container environments.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-759: Use of a One-Way Hash without a Salt, where the product uses a one-way cryptographic hash against an input that should not be reversible, such as a password, but the product does not also use a salt as part of the input. In Github.com/neuvector/neuvector, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Impact\n\nNeuVector stores user passwords and API keys using a simple, unsalted hash. This method is vulnerable to rainbow table attack (offline attack where hashes of known passwords are precomputed).\n\nNeuVector generates a cryptographically secure, random 16-character salt and uses it with the PBKDF2 algorithm to create the hash value for the following actions:\n\n- Creating a user\n- Updating a user’s password\n- Creating an API key\n\n**Note:** After upgrading to NeuVector 5.4.6, users must log in again so that NeuVector can regenerate the password hash. For API keys, you must send at least one request per API key to regenerate its hash value.\n\n### Patches\n\nThis issue is fixed in NeuVector version **5.4.6** and later.\n\n### Workarounds\n\nThere is no workaround. Upgrade to a patched version of NeuVector as soon as possible.\n\n### References\n\nIf you have any questions or comments about this advisory:\n\n- Reach out to the [SUSE Rancher Security team](https://github.com/rancher/rancher/security/policy) for security related inquiries.\n- Open an issue in the [NeuVector](https://github.com/neuvector/neuvector/issues/new/choose) repository.\n- Verify with our [support matrix](https://www.suse.com/suse-neuvector/support-matrix/all-supported-versions/neuvector-v-all-versions/) and [product support lifecycle](https://www.suse.com/lifecycle/#suse-security).",
