Cross-Site Scripting Attacks (XSS) By utilizing input validation errors, a hacker can carry out a cross-site scripting attack. Types of XSS: Reflected/Non-Persistent: This XSS attack involves sharing a malicious script through a payload in a shared URL. Users click this URL and unwillingly execute the payload, running the script on a vulnerable website, which is then reflected to the user. Stored/Persistent: Similar to a reflected attack, but the attacker uploads their malicious script to the web server itself, instead of relying on a user to inject the code. Document Object Model (DOM): An application programming interface (API) for HTLM and XLM documents, which allows scripting language use in web applications. A DOM-based XSS modifies the DOM environment in a victim’s browser, which causes the client to run code without the user’s knowledge. XSS Defense: Best practice is to sanitize all data input before it can run on the server and user education to prevent clicking on suspicious links. Mehr sehen
