CVE-2023-27573

Netboxlabs Netbox-docker hard-coded credentials

9.0 CRITICALPublic exploitEPSS 0.50%
  1. Published11 Mar 2026

Description

netbox-docker before 2.5.0 has a superuser account with default credentials (admin password for the admin account, and 0123456789abcdef0123456789abcdef01234567 value for SUPERUSER_API_TOKEN). In practice on the public Internet, almost all users changed the password but only about 90% changed the token. Having a default token value was intentional and was valuable for the main intended use case of the netbox-docker product (isolated development networks). Some users engaged in an effort to repurpose netbox-docker for production. The documentation for this effort stated that the defaults must not be used. However, installation did not ensure non-default values. The Supplier was aware of the CVE ID assignment and did not object to the assignment.
