About the product:
Palo Alto Traps is an advanced endpoint protection suite that detects attacks 
such as memory corruption, executable child processes, DLL hijacking, etc.  
Aside from optionally blocking it, it sends this ?trap? to a central server for 
logging purposes.

About the vulnerability:
An attacker can send a SOAP request with JavaScript embedded inside it, which 
gets stored in the database.  When an administrator monitors the Traps? admin 
screen and opens details about the vulnerability, the JavaScript is executed on 
the admin browser.

The XSS works in the <b:Arguments>, <b:FileName> and <b:URL> parameters, for 
example:

  <b:Arguments>"C:\\Users\\Michael\\fake.exe" 
    &#0000060;script&#0000062;
      alert("xss");
    &#0000060;/script&#0000062;
  </b:Arguments>
