XSS (Cross-Site Scripting)
What is XSS (Cross-Site Scripting)?
Cross-Site Scripting (XSS) is a type of security vulnerability where an attacker injects malicious scripts into otherwise trusted websites. When a user visits the compromised page, the script executes in their browser, allowing the attacker to steal sensitive information like session cookies or login credentials. In the context of fintech, XSS is a critical threat that can lead to unauthorized access to payment accounts and personal financial data.
Why It Matters
-
It poses a significant risk to payment gateways and banking portals by potentially exposing user session tokens to malicious actors.
-
Attackers can use XSS to redirect users to fraudulent pages or manipulate the content of a financial application to facilitate phishing.
-
Implementing robust input validation and output encoding is essential for SaaS platforms to protect their customers from script injection attacks.
