NeuVector has an insecure password storage vulnerable to rainbow attack

CVE-2025-53884 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Impact

NeuVector 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).

NeuVector generates a cryptographically secure, random 16-character salt and uses it with the PBKDF2 algorithm to create the hash value for the following actions:

  • Creating a user
  • Updating a user’s password
  • Creating an API key

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.

Patches

This issue is fixed in NeuVector version 5.4.6 and later.

Workarounds

There is no workaround. Upgrade to a patched version of NeuVector as soon as possible.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
