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. Greets: Jack, the general, www.wehack.com ~`TOBY`~ UPDATE JUNE 21ST ITS NOT RANDOM NUMBERS ITS THE TICKET NUMBER YOU ARE GIVEN! ALL SERVERS ARE VULNERABLE
