Which languages are vulnerable to Cross Site Scripting attacks ?

  1. Java

  2. ASP.Net

  3. Perl

  4. All of the above


Correct Option: D
Explanation:

To solve this question, the user needs to have knowledge of Cross Site Scripting (XSS) and the programming languages that can be vulnerable to it.

Cross Site Scripting (XSS) is a type of web vulnerability that allows attackers to inject malicious code into web pages viewed by other users. This can result in the theft of sensitive data, such as login credentials, bank account information, and other personal information.

Now, let's go through each option and explain why it is right or wrong:

A. Java: Java web applications can be vulnerable to XSS attacks if they do not properly sanitize user input. This makes option A partially correct.

B. ASP.Net: ASP.Net web applications can also be vulnerable to XSS attacks if they do not properly sanitize user input. This makes option B partially correct.

C. Perl: Perl web applications can also be vulnerable to XSS attacks if they do not properly sanitize user input. This makes option C partially correct.

D. All of the above: Since options A, B, and C are all partially correct, option D is the correct answer. All of the above languages are vulnerable to XSS attacks if they do not properly sanitize user input.

Therefore, the correct answer is: D
