Joomla Googlemaps 3.2 Cross Site Scripting / Denial Of Service vulnerabilitie

Code
`Hello list!  
  
Earlier I wrote about multiple vulnerabilities in Googlemaps plugin for  
Joomla (http://securityvulns.ru/docs29645.html). After my informing, the  
developer fixed these vulnerabilities in versions 2.19 and 3.1 of the  
plugin - by removing proxy functionality. And in version 3.2 of the plugin  
he introduced new proxy functionality, which must be protected against  
previous attacks. But after my checking, I've found two holes in the last  
version of the plugin.  
  
These are Denial of Service and Cross-Site Scripting vulnerabilities in  
Googlemaps plugin for Joomla.  
  
-------------------------  
Affected products:  
-------------------------  
  
Vulnerable is Googlemaps plugin v3.2 for Joomla. I've informed the developer  
about these holes. Now he is working on a new version.

Details:  
----------  
  
To bypass protection for accessing this script it's needed to set referer,  
cookie and token. The referer is current site, the cookie is set by the site  
(Joomla) itself and the token can be found at page which uses plugin of the  
site (and it's setting in URL). This data can be taken from the site  
automatically.  
  
Referer: http://site  
Cookie: dc9023a0ff4f8a00f9b2f4e7600c17f4=69c59f0263b70f9343e0a75a93bd44a0  
  
Denial of Service (WASC-10):

Besides conducting DoS attack manually, it's also possible to conduct  
automated DoS and DDoS attacks with using of DAVOSET  
(http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2013-July/008879.html).  
  
Cross-Site Scripting (WASC-08):
