External Frames Node

External frames allow a website to load and display any content from other sources.

Previously, frames were widely used to surf a website without going into another web page. However, this has become obsolete in modern websites. Frames also make indexing more difficult for search engines. And it's difficult for people to bookmark web pages. The World Wide Web Consortium (W3C) recommends that developers do not use frames in their web pages. HTML5, for instance, does not support the <frame> tag.

Frames may pose dangers to the security of web applications. To illustrate, a frame injection attack involves an attacker injecting a frame into a web page. The injected website can be redirected to a different URL, initiating top-level navigation. Users could easily be directed to a compromised website. This is why it is crucial for security professionals to know about all external objects in their web applications.

Once the scan is completed, all external frames are listed under the External Frames node in the Knowledge Base. You can access the same information in the Knowledge Base Report and Knowledge Base Tab.

Netsparker forms Knowledge Base Nodes on its findings. If the External Frames node is not listed, it means that Netsparker did not find any.

For further information, see Knowledge Base Node.
