What Is Cross-Site Scripting?
Notas do episódio
Cross-site scripting, or XSS, occurs when an application allows malicious script content to execute in another user’s browser within the context of a trusted website. Certification exams may ask candidates to distinguish stored, reflected, and document-based forms of XSS or identify the appropriate defensive control. A stored attack saves malicious content in a database or page, while a reflected attack returns crafted input in an immediate response. Successful exploitation may expose session information, alter displayed content, redirect users, capture input, or perform actions using the victim’s authenticated session. Defenses include context-aware output encoding, safe templating, input handling, content security policies, secure cookie settings, and frameworks that escape untrusted data automatically. Investigators should identify where the script entered the application, which users viewed it, and whether sessions or accounts were affected.
