neuvector: Use of Default Password
CVE-2025-8077 is a critical-severity use of default password vulnerability in neuvector from SUSE, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 5.4.6 as the first without the flaw, so updating neuvector to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.56% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update neuvector to 5.4.6 or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A vulnerability exists in NeuVector versions up to and including 5.4.5, where a fixed string is used as the default password for the built-in `admin` account. If this password is not changed immediately after deployment, any workload with network access within the cluster could use the default credentials to obtain an authentication token. This token can then be used to perform any operation via NeuVector APIs.

The underlying weakness: Use of Default Password
The product uses default passwords for potentially critical functionality.
How developers prevent this class of flaw
- Prohibit use of default, hard-coded, or other values that do not vary for each installation of the product - especially for separate organizations.
- Ensure that product documentation clearly emphasizes the presence of default passwords and provides steps for the administrator to change them.
- Force the administrator to change the credential upon installation.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: total).
- Record last changed materially (score, affected products, status or references).
