Sample Question + Solution Explanation

You are a security analyst working for a medium-sized organization. Your organization has recently deployed a new web application that allows customers to log in and view their accounts. During a routine vulnerability scan, you notice that there are several cross-site scripting (XSS) vulnerabilities present in the application. Which of the following would be the MOST effective mitigation for XSS vulnerabilities?

A) Install a web application firewall (WAF) to filter malicious input

B) Ensure that the web application uses SSL/TLS for secure communication

C) Sanitize user input and output data to remove dangerous code

D) Use multi-factor authentication for all user logins

Solution Explanation:

Correct Answer: C) Sanitize user input and output data to remove dangerous code

Explanation:

Cross-Site Scripting (XSS) vulnerabilities are a result of user-supplied data being included in web pages without proper validation or sanitization. Malicious users can inject JavaScript or HTML code into the application, potentially compromising the session or stealing sensitive information.

Sanitizing user input and output data ensures that any data provided by the user (such as from a form or URL) is properly filtered or encoded before being rendered on the page, making it impossible for attackers to execute harmful code. This is the most effective mitigation because it directly addresses the root cause of XSS vulnerabilities.

Option A) Install a web application firewall (WAF) to filter malicious input

Explanation:

While a Web Application Firewall (WAF) can provide some protection by filtering and blocking malicious HTTP requests, it is not a comprehensive solution for XSS vulnerabilities. WAFs may not catch every potential attack, especially if the malicious script is subtle or embedded in more complex payloads. Therefore, a WAF should not be relied upon as the primary defense against XSS; proper input sanitization should always be the first line of defense.

Option B) Ensure that the web application uses SSL/TLS for secure communication

Explanation:

Using SSL/TLS (Secure Sockets Layer/Transport Layer Security) ensures that the data sent between the client and the server is encrypted, protecting against man-in-the-middle (MITM) attacks and eavesdropping. However, SSL/TLS does not address XSS vulnerabilities, as it only focuses on encryption during data transmission.

This option is important for securing the communication channel but does not mitigate the risk of XSS attacks. Therefore, it is not the most effective mitigation for XSS.

Option D) Use multi-factor authentication for all user logins

Explanation:

Multi-factor authentication (MFA) adds an additional layer of security to the login process by requiring users to provide more than one form of identification (e.g., password and authentication code). While MFA enhances the security of user accounts by preventing unauthorized access, it does not directly address XSS vulnerabilities.

In the context of mitigating XSS, MFA is not a solution because XSS attacks are more about exploiting vulnerabilities in the web application rather than compromising login credentials. Therefore, MFA is not relevant to the XSS vulnerability issue.
