  # Exploit Title: 0day Drupal <= 6.15 Multiple Permanent XSS # Date: 07 01 2009 # Author: Emanuele &apos;emgent&apos; Gentili # Software Link: http://ftp.drupal.org/files/projects/drupal-6.15.tar.gz # Version: Drupal <= 6.15 # CVE : N/A # Code : http://www.backtrack.it/~emgent/exploits/DrupalMultiplePermanentXss-20090107.txt # Special Ironic greetz: Károly Négyesi and Heine Deelstra. (Drupal Security Team)     [+] Vulnerability Descrition: Drupal 6.15 (latest release) is vulnerable to multiple permanent Cross Site Scritpting and probably the old release too. The severity is anyway low, because an attacker can use it only if he has an access to "User Management" with the right privileges. The first vulnerability is up in "Access rules". In fact the attacker can write a code in "Mask" entry textbox and after the submit the code will be executed. The second vulnerability, similar to the first, is allocated in "Roles management", in fact the attacker, can use "Name Role" for add malicius code, that will be executed after the submit viewing the related page list. These vulnerabilities are "permanent". [+] Possible Case History: 1) The attacker named A sniffs the password to authorized user that can manage "User Management" in www.example.com. A logs in with the sniffed credentials to join "Access Rules" management and create a malicious javascript code to grab all visitors cookies, and send them to his own server. The attacker could own the admin&apos;s system by creating a malicious javascript. To try that out, he owns his own browser. When the admin user will join the XSSed page, the attacker will execute the attacks with really big possibility to hack his browser and system using some known/unknown browser issues. 2) The attacker named A sniffs the password of the authorized user that can manage "User Management" in www.example.com. A logs in with the sniffed credentials to join "Name Role" management and create a malicious javascript code to grab all visitors&apos; cookies, and send them to his own server. The attacker saves the code as "new name role", and logs out of this drupal platform. At this point all users associated to the new role name will be a bridge for showing and sending (client side) the information requested via the malicious javascript. The autenticated user A, by viewing his profile on drupal causes the javascript to grab his cookies and afterwards send login data to the attacker system. Another scenario can be user XSS to manage all clients&apos; (not logged, too) browsers always via Javascript (client side). [+] Conclusion The severity is low but the scenario can be moderate, the management and the drupal configuration are really impressive and the possibility to switch tasks and functions too. With this possibility according to first and second scenarios, admins and users can be hacked.
