Re: excessive xss vulnerabilities

Interesting, a JS keylogger! You should use XMLHTTP to post the info...



A presentation by Jeremiah Grossman at blackhat last year walked through installing a keylogger and using
AJAX (HTMLHTTP) to not only record what the user was doing, but also interactively feed them new payloads.

Subject: [Full-disclosure] excessive xss vulnerabilities


there is a high volume of xss vulnerabilities on this list. take the
next step to disclose why xss important for the affected program. for
instance, creating a test case that does something privileged or
malicious towards a visitor. in attempting to create a keystroke logger
in javascript i've found it drops random keystrokes (i think its a speed
problem). and i would be interested in seeing more malicious javascript.


again please justify why xss is valuable in disclosures of these
vulnerabilties
even if its just a cookie stealer, please show why an attacker would
want those cookies or how he/she could use them to create a security
issue.=20

thanks
