CVE-2024-38972Network attack vector

Browser script execution via unescaped Name input

Published Jul 9, 2024 · Updated Aug 2, 2024

Cross-site scripting in NetBox 4.0.3 allows attackers to run arbitrary script in a user's browser through the power-port Name field. The /dcim/power-ports/add/ endpoint accepts crafted Name input and places it into web-page output without neutralizing executable HTML or JavaScript. Exploitation requires a victim to render the injected output, and published records disagree on whether field-edit privileges are required.
