Not Founds Node

Not Founds in the Knowledge Base provides a sample list of 404 errors found in the target web application. The HTTP 404 error message is a response code to show that the server could not find the requested web page.

Acunetix 360 works by crawling and attacking web applications to detect vulnerabilities. During crawling, it attempts to reach every link in the website, and traverses web forms to access web pages that are typically only accessible once the form is submitted.

During this process, some web pages may return a 404 Error as Acunetix 360 tries to find out some hidden resources using a reference list of the most common file and directory names. This error indicates that the server cannot find what the client has requested.

This is not a vulnerability. The scanner provides the list only to inform you that these pages are not reachable and therefore cannot be scanned. If you think that the list is incorrect, consider changing your Custom 404 settings in the Scan Policy.

Once the scan is completed, all not founds are listed under the Not Founds node in the Knowledge Base. You can access the same information in the Knowledge Base Report and Knowledge Base Tab.



Acunetix 360 forms Knowledge Base nodes on its findings. If the Not Founds node is not listed, it means that Acunetix 360 did not find any.

For further information, see Knowledge Base Nodes.
