How is an XSS post vulnerability different from a GET request?
The XSS via Post is different in that it happens when the response comes back and executes the additional code (malicious payload) as a result. Either way – the attacker would have to do this using those methods as it’s not possible to send someone a link for an XSS POST vulnerability like you can with a GET request.
Which is the best way to exploit an XSS?
Overwrite the current URI with “/login.php”, making it look like the victim is located at the login page (The URL bar will look like /login.php). Overwrite all forms so that when the victim logs in, it will submit their credentials to “ http://evildomain/logpasswords ”.
What should I do if my website is vulnerable to XSS?
If one part of a website is vulnerable, there is a high likelihood that there are other problems as well. The primary defenses against XSS are described in the OWASP XSS Prevention Cheat Sheet. Also, it’s crucial that you turn off HTTP TRACE support on all web servers.
Where does a XSS attack take place on a computer?
XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user. Flaws that allow these attacks to succeed are quite widespread and occur anywhere a web application uses input from a user within the output it generates without validating or encoding it.
How can I get XSS on my post?
Other methods of XSS for POST, could be something like a malicious ad/iframe injected into the victims viewed pages, private message on social network, text message, or from the same LAN and injected with MITM attacks.
How is XSS reflected through the post method?
A large portion of sites (smaller) don’t implement CSRF tokens, so code (site functions) can be executed from anywhere on behalf of the authenticated user as you stated above. The XSS via Post is different in that it happens when the response comes back and executes the additional code (malicious payload) as a result.
