    CVE-2026-29514 (GCVE-0-2026-29514)

    Vulnerability from cvelistv5 – Published: 2026-05-04 16:05 – Updated: 2026-05-21 14:38 X_Open Source
    VLAI
    Title
    NetBox 4.3.5 - 4.5.4 RCE via RenderTemplateMixin
    Summary
    NetBox versions 4.3.5 through 4.5.4 contain a remote code execution vulnerability in the RenderTemplateMixin.get_environment_params() method that allows authenticated users with exporttemplate or configtemplate permissions to execute arbitrary code by specifying malicious Python callables in the environment_params field. Attackers can bypass Jinja2 SandboxedEnvironment protections by setting the finalize parameter to any importable Python callable such as subprocess.getoutput, which is invoked on every rendered expression outside the sandbox's call interception mechanism, achieving remote code execution as the NetBox service user.

    CVE-2023-27573 (GCVE-0-2023-27573)

    Vulnerability from cvelistv5 – Published: 2026-03-11 00:00 – Updated: 2026-03-11 14:23
    VLAI
    Summary
    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.
