Can XSS cause CSRF?
If the tokens are generated by the server, then XSS can be used to read (GET) a page on the server (XMLHttpRequest), record the valid token and embed it in the malicious requests, making CSRF possible.
What information can the attacker steal using XSS attacks?
XSS is a versatile attack vector which opens the door to a large number of social-engineering and client-side attacks. As shown, it could be used to steal sensitive information, such as session tokens, user credentials or commercially valuable data, as well as to perform sensitive operations.
Why are some web applications vulnerable to XSS?
We compiled a Top-10 list of web applications that were intentionally made vulnerable to Cross-site Scripting (XSS). They were created so that you can learn in practice how attackers exploit Cross-site Scripting vulnerabilities by testing your own malicious code.
How can XSS be manipulated by an attacker?
There are a few methods by which XSS can be manipulated: The malicious code is inserted in the application (usually as a link) by the attacker. The code is activated every time a user clicks the link. The attacker delivers a malicious link externally from the vulnerable web site application to a user.
What kind of vulnerability is cross site scripting?
Cross-site scripting (XSS) is a type of vulnerability where the code sent by the attacker is executed back in the user’s browser. The malicious code is written in a scripting language, usually JavaScript. Learn more about cross-site scripting in general.
Can a CSRF attack be prevented by SSL?
Moreover, using SSL does not prevent a CSRF attack, because the malicious site can send an “https://” request. Typically, CSRF attacks are possible against web sites that use cookies for authentication, because browsers send all relevant cookies to the destination web site. However, CSRF attacks are not limited to exploiting cookies.
