AI-suggested
- Implement strict input validation and output encoding on the 'Name' parameter at /dcim/power-feeds/add to neutralize malicious scripts.
- Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing NetBox.
- Restrict access to the vulnerable endpoint to trusted users or networks until an official patch is released.
- Educate users about the risks of clicking on suspicious links and implement email filtering to reduce phishing attempts.
- Monitor web server logs and application logs for unusual requests containing suspicious payloads targeting the Name parameter.
- Regularly update NetBox to the latest version once a patch addressing this vulnerability is available.
- Consider deploying Web Application Firewalls (WAF) with rules to detect and block XSS attack patterns targeting NetBox.
- Conduct internal security assessments and penetration tests focusing on web input handling to identify similar vulnerabilities.
Description
A cross-site scripting (XSS) vulnerability in netbox v4.0.3 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Name parameter at /dcim/power-feeds/add.
