Exam CS0-002 topic 1 question 322 discussion

D is a better choice. Browser XSS Protection is already deprecated by Edge, Chrome, and Firefox. Server-side XSS not only protect the end-user, but many other users.

The OWASP ZAP output indicates that the web browser's XSS (Cross-Site Scripting) protection is not enabled or is disabled by the configuration of the HTTP Response header. To address this vulnerability, you should enable the browser's XSS filter. This filter helps protect against certain types of client-side XSS attacks by identifying and blocking malicious scripts from executing in the browser.

A security analyst should also consider that other users will also access the website, so a server side fix is necessary. Implementing a fix on your own machine/browser will not fix the vulnerability on another users' machines/browsers.

Agree with karpal, source cited is very clear.

"Web Browser XSS Protection not enabled" means that Web browser XSS protection is not enabled or is disabled by the configuration of the 'X-XSS-Protection' HTTP response header on the webserver.

GPT: To mitigate this vulnerability, you should enable the browser's XSS filter. This is the most appropriate solution among the given options because it directly addresses the issue identified in the scan output. Here's a brief explanation of the other options: B. Enable Windows XSS protection: This is not the correct solution because the issue is related to the web browser and not the underlying Windows operating system. C. Enable the browser's protected pages mode: While this might provide some protection against certain attacks, it is not specifically related to XSS protection and would not fully address the identified vulnerability. D. Enable server-side XSS protection: While server-side XSS protection is important, it is not the direct solution to the issue identified in the scan output. The vulnerability in question is related to the browser's XSS filter, which is a client-side protection mechanism

Enabling server-side XSS protection is not a direct solution to the vulnerability identified in the alert, as it would not address the configuration of the HTTP Response header.

I'm going with A. There's nothing that says that domain.com is your company's webserver, so implementing a server-side fix may not be an option. A client-side fix is certainly under your control, so I think it's the best answer.

Agree with D

"while testing for client-side vulnerabilities" Why then would we use XSS on the server side?
