Question

kevin is an attacker who is exploiting vulnerabilities by performing an xss attack. what are two types of exploitations that he can perform?

Answer 1

Kevin can exploit vulnerabilities using Stored XSS and Reflected XSS, potentially accessing sensitive information or performing unauthorized actions on behalf of the victim.

Step-by-step explanation:

Kevin, as an attacker exploiting vulnerabilities through an XSS attack, can perform various types of exploitations. The two main types of exploitations are:

• Stored XSS - This happens when the malicious script is permanently stored on the target servers, such as in a database, message forum, visitor log, or comment field. The victim retrieves the malicious script from the server when they access the relevant web page or application.
• Reflected XSS - This occurs when the attacker sends a malicious script to a user's browser, typically through a link that appears to be from a trustworthy source. When the user clicks the link, the HTTP request is reflected back by the webserver with the XSS code included, which is then executed in the user's browser.

Through these attacks, hackers can gain unauthorized access to cookies, session tokens, or other sensitive information retained by the browser and used with that site. They can also maliciously redirect the victim to another page or site, or even perform actions on behalf of the victim without their consent.
