You say the attack surface is limited to only yourself, but... Google "Session Riding", "CSRF" and look at scripts like this: http://www.spidynamics.com/spilabs/js-port-scan/ to give you an idea of all the things you can potentially do with an arbitrary script injection vulnerability. Two important principles to absorb: 1) You don't always know WTH your browser is busy doing 2) It's not always *you* that guiding your browser -ae

If the returned page contains the original user input and execute the script, then we confirm that user input is not sanitized and XSS exists. My question is if the user inputs are not displayed to any other users ANYWHERE in the application, what's the impact of this XSS vulnerability? Or are we still consider this as an XSS vulnerability? Can malicious intruders still take advantage of this? regards, Rick Zhong -------------------------------------------------------------- ---------------- This List Sponsored by: Cenzic Concerned about Web Application Security?
