Detection Guidance

This vulnerability occurs in the '/blog' endpoint of Navigate CMS versions prior to 2.9.6, where user input passed through specific query parameters is not properly sanitized, leading to reflected Cross-Site Scripting (XSS).

To detect this vulnerability on your system, you can test the '/blog' endpoint by injecting typical XSS payloads into query parameters and observing if the input is reflected unsanitized in the HTML response.

• Use curl or similar tools to send requests with XSS payloads, for example: curl -i "http://your-navigate-cms-site/blog?param=<script>alert(1)</script>"
• Check the HTTP response for the presence of the injected script tags or JavaScript code being reflected without proper encoding.
• Use web vulnerability scanners that support XSS detection targeting the '/blog' endpoint.

Mitigation Strategies

The vulnerability was fixed in Navigate CMS version 2.9.6. The immediate step is to upgrade your Navigate CMS installation to version 2.9.6 or later.

If upgrading immediately is not possible, consider implementing input validation and output encoding on the '/blog' endpoint to prevent unsafe HTML rendering.

Additionally, apply web application firewall (WAF) rules to detect and block typical XSS attack patterns targeting the vulnerable endpoint.
