TL;DR
Cross frame scripting (CFS) is a type of cross-site scripting (cyber security) attack that exploits vulnerabilities in how websites handle iframes. It’s less common than traditional XSS, but still dangerous. This guide explains how to identify potential CFS attacks and implement measures to block them.
Understanding Cross Frame Scripting
CFS relies on tricking a website into loading content from a malicious source within an iframe. If the website doesn’t properly restrict what that iframe can do, the attacker can potentially access sensitive data or perform actions as if they were the user.
