Security Analysis not enabled

Cross-Site Scripting
Cross-Site Scripting enables an attacker to inject code into the response of a web-request that is viewed by other users. It can for example be used to bypass access controls, or even to take over other users' accounts.
File Exposure
File Exposure allows an attacker to gain access to local files that he should not be able to access. These files can for example include database credentials, or other configuration files.
File Manipulation
File Manipulation enables an attacker to write custom data to files. This potentially leads to injection of arbitrary code on the server.
Object Injection
Object Injection enables an attacker to inject an object into PHP code, and can lead to arbitrary code execution, file exposure, or file manipulation attacks.
Code Injection
Code Injection enables an attacker to execute arbitrary code on the server.
Response Splitting
Response Splitting can be used to send arbitrary responses.
File Inclusion
File Inclusion enables an attacker to inject custom files into PHP's file loading mechanism, either explicitly passed to include, or for example via PHP's auto-loading mechanism.
Command Injection
Command Injection enables an attacker to inject a shell command that is execute with the privileges of the web-server. This can be used to expose sensitive data, or gain access of your server.
SQL Injection
SQL Injection enables an attacker to execute arbitrary SQL code on your database server gaining access to user data, or manipulating user data.
XPath Injection
XPath Injection enables an attacker to modify the parts of XML document that are read. If that XML document is for example used for authentication, this can lead to further vulnerabilities similar to SQL Injection.
LDAP Injection
LDAP Injection enables an attacker to inject LDAP statements potentially granting permission to run unauthorized queries, or modify content inside the LDAP tree.
Header Injection
Other Vulnerability
This category comprises other attack vectors such as manipulating the PHP runtime, loading custom extensions, freezing the runtime, or similar.
Regex Injection
Regex Injection enables an attacker to execute arbitrary code in your PHP process.
XML Injection
XML Injection enables an attacker to read files on your local filesystem including configuration files, or can be abused to freeze your web-server process.
Variable Injection
Variable Injection enables an attacker to overwrite program variables with custom data, and can lead to further vulnerabilities.

// BigDump ver. 0.36b from 2015-04-30
// Staggered import of an large MySQL Dump (like phpMyAdmin 2.x Dump)
// Even through the webservers with hard runtime limit and those in safe mode
// Works fine with latest Chrome, Internet Explorer and Firefox

// Author:       Alexey Ozerov (alexey at ozerov dot de) 
//               AJAX & CSV functionalities: Krzysiek Herod (kr81uni at wp dot pl)

// terms of the GNU General Public License as published by the Free Software Foundation;
// either version 2 of the License, or (at your option) any later version.

// THIS SCRIPT IS PROVIDED AS IS, WITHOUT ANY WARRANTY OR GUARANTEE OF ANY KIND

// USAGE

// 1. Adjust the database configuration and charset in this file
// 2. Remove the old tables on the target database if your dump doesn't contain "DROP TABLE"
// 3. Create the working directory (e.g. dump) on your web server
// 4. Upload bigdump.php and your dump files (.sql, .gz) via FTP to the working directory
// 5. Run the bigdump.php from your browser via URL like http://www.yourdomain.com/dump/bigdump.php
// 6. BigDump can start the next import session automatically if you enable the JavaScript
// 7. Wait for the script to finish, do not close the browser window
// 8. IMPORTANT: Remove bigdump.php and your dump files from the web server

// If Timeout errors still occure you may need to adjust the $linepersession setting in this file

// LAST CHANGES

// *** Fix a typo in HTML code
// *** Change from mySQL to mySQLi

// Database configuration

$db_server   = XOOPS_DB_HOST; // database server
$db_name     = XOOPS_DB_NAME; // database name
$db_username = XOOPS_DB_USER; //  database login
$db_password = XOOPS_DB_PASS; // database password

// Connection charset should be the same as the dump file charset (utf8, latin1, cp1251, koi8r etc.)
// See http://dev.mysql.com/doc/refman/5.0/en/charset-charsets.html for the full list
// Change this if you have problems with non-latin letters

$db_connection_charset = 'utf8';

// OPTIONAL SETTINGS 

$filename           = '';     // Specify the dump filename to suppress the file selection dialog
$ajax               = true;   // AJAX mode: import will be done without refreshing the website
$linespersession    = 3000;   // Lines to be executed per one import session
$delaypersession    = 0;      // You can specify a sleep time in milliseconds after each session
                              // Works only if JavaScript is activated. Use to reduce server overrun

// CSV related settings (only if you use a CSV dump)

$csv_insert_table   = '';     // Destination table for CSV files
$csv_preempty_table = false;  // true: delete all entries from table specified in $csv_insert_table before processing
$csv_delimiter      = ',';    // Field delimiter in CSV file
$csv_add_quotes     = true;   // If your CSV data already have quotes around each field set it to false
$csv_add_slashes    = true;   // If your CSV data already have slashes in front of ' and " set it to false

// Allowed comment markers: lines starting with these strings will be ignored by BigDump

$comment[]='#';                       // Standard comment lines are dropped by default
$comment[]='-- ';
$comment[]='DELIMITER';               // Ignore DELIMITER switch as it's not a valid SQL statement
// $comment[]='---';                  // Uncomment this line if using proprietary dump created by outdated mysqldump
// $comment[]='CREATE DATABASE';      // Uncomment this line if your dump contains create database queries in order to ignore them
$comment[]='/*!';                     // Or add your own string to leave out other proprietary things

// Pre-queries: SQL queries to be executed at the beginning of each import session

// $pre_query[]='SET foreign_key_checks = 0';

// $pre_query[]='Add additional queries if you want here';

// Default query delimiter: this character at the line end tells Bigdump where a SQL statement ends
// Can be changed by DELIMITER statement in the dump file (normally used when defining procedures/functions)

$delimiter = ';';

// String quotes character

$string_quotes = '\'';                  // Change to '"' if your dump file uses double qoutes for strings

// How many lines may be considered to be one query (except text lines)
