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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
