Description

WhiteHat Security (whitehatsec.com) has found an xss vulnerability with the <s:textfield> tag. When loading a url in a browser with some param name, in this case "myinput", and the jsp being loaded has the tag <s:textfield name="myinput" id="myinput"></s:textfield>, an alert message is popped open in the browser- which is WhiteHat's method of showing the vulnerability. Example url is: http://localhost:8080/sample.action?myinput=%fc%80%80%80%80%a2%fc%80%80%80%80%bE%FC%80%80%80%80%BC%FC%80%80%80%81%B7%FC%80%80%80%81%A8%FC%80%80%80%81%B3%FC%80%80%80%81%A3%FC%80%80%80%81%A8%FC%80%80%80%81%A5%FC%80%80%80%81%A3%FC%80%80%80%81%AB%FC%80%80%80%80%BE%fc%80%80%80%80%bCscript%fc%80%80%80%80%bEalert%fc%80%80%80%80%a81%fc%80%80%80%80%a9%fc%80%80%80%80%bC%fc%80%80%80%80%aFscript%fc%80%80%80%80%bE
