SQL INJECION - TIPS & TRICKS - METHODOLOGIES

############################
# What you should look for #
############################
Try to look for pages that allow you to submit data (i.e: login page, search page, feedback, etc).
Sometimes, HTML pages will use the POST command to send parameters to another ASP page. Therefore, you may not see the parameters in the URL.
However, you can check the source code of the HTML, and look for "FORM" tag in the HTML code. You may find something like this in some HTML codes:
<FORM action=Search/search.asp method=post>
<input type=hidden name=A value=C>
</FORM>
Everything between the <FORM> and </FORM> have potential parameters that might be useful (exploit wise).
#####################################################
# What if you can't find any page that takes input? #
#####################################################
You should look for pages like ASP, JSP, CGI, or PHP web pages. Try to look especially for URL that takes parameters, like: http://[site.com]/page.asp?id=10 ########################################
# How do you test if it is vulnerable? #
########################################
Start with a single quote trick. Input something like: hi' or 1=1--
Into login, or password, or even in the URL. Example:
- Login: hi' or 1=1--
- Pass: hi' or 1=1-- or - http://[site.com]/page.asp?id=hi' or 1=1--
If you must do this with a hidden field, just download the source HTML from the site, save it in your hard disk, modify the URL and hidden field accordingly. Example:
<FORM action=http://site.com/Search/search.asp method=post>
<input type=hidden name=A value="hi' or 1=1--">
</FORM>
If luck is on your side, you will get login without any login name or password. You can also do this with a local proxy like Paros…...

Methodologies

...Methodologies Compare and contrast between qualitative and quantitative research methodologies. How would you apply each type of research methodology at work? Qualitative research methodology is conducted on site or location of the study where the data are collected, with the research as the key instrument. Instead of numbers, words and pictures such as transcripts of in-depth interviews, field notes, photographs, tapes, memos, personal documents, and other official records are used to collect data. The process from beginning to end or history is more important in this type of method than the outcome of what happened. Information or data collected are not to be approved or disapproved by hypothesis, but are gathered then separated into groups for further evaluation. Why people do the things they do is very important to researchers in the qualitative method, they are concerned with how different people/culture live their lives and make sense of them by looking for common ground. Quantitative research methodology on the other hand, is conducted to ensure objectivity, generalizability and reliability, by testing, retesting and post testing subjects of the study for effectiveness. It relies mostly on numbers, counts, measures, operational values, quantifiable coding, quantitative data and statistical data. Its’ audience is much broader and generalized than that of the qualitative method and investigators would usually go into a study with predetermined questions; methods...

Sql Injection Methodology

...SQL Injection - Extracting database data from the page content up vote 4 down vote favorite I have a question I am hoping someone could help with.. I am in the process of writing an SQL Injection tool from scratch (I am aware there are already excellent tools out there such as SQL Map, but this one has to be written from scratch). The problem I am having: When manually performing SQL injection to determine tables names or column names and so on using strings such as: www.vulnerable site.net/articles.php?id =-1 union select 1,2,group_concat(column_name),4 from information_schema.columns -- or www.vulnarable site.net/articles.php?id =-1 union select 1,2,table_name,4 from information_schema.tables -- it is easy to determine the table names/column names as you can simply look at the page and read the column names that are returned in the page content. But how can this be done in an automated way? Doing this in an automated fashion is a lot harder though because how does the tool know what on the page that is returned when the sql injection is executed are table names/column names? What would be the most reliable way to do this so the tool knows what parts of the page content to extract because they are table names/column names? for example... could I parse/search the page content for strings seperated by commas to get the table and column names that are output by the injection? Is there better more reliable ways to do it? your help with......

A Survey of Sql Injection Defense Mechanisms

...A Survey of SQL Injection Defense Mechanisms Kasra Amirtahmasebi, Seyed Reza Jalalinia and Saghar Khadem Chalmers University of Technology, Sweden akasra, seyedj, saghar{@student.chalmers.se} Abstract SQL Injection Attack (SQLIA) is a prevalent method which makes it possible for the attackers to gain direct access to the database and culminates in extracting sensitive information from the firm’s database. In this survey, we have presented and analyzed six different SQL Injection prevention techniques which can be used for securing the data storage over the Internet. The survey starts by presenting Variable Normalization and will continue with AMNESIA, Prepared statements, SQL DOM, SQLrand and SQLIA prevention in stored procedures respectively. that determining whether a SQL statement is allowable or not is done by checking the existence of normalized statement in the ready-sorted allowable list. 2.1. Background Many web pages ask users to input some data and make a SQL queries to the database based on the information received from the user i.e. username and passwords. By sending crafted input a malicious user can change the SQL statement structure and execute arbitrary SQL commands on the vulnerable system. Consider the following username and password example, in order to login to the web site, the user inputs his username and password, by clicking on the submit button the following SQL query is generated: SELECT * FROM user_table WHERE user_id = ‘john’ and......

Lethal Injection

...Lethal Injection On January 16, 2014 an Ohio death row inmate was put to death by lethal injection with an untested drug. After being injected with the drug, the inmate quickly began to choke and gasp for air. This process which appeared to be painful and hard to watch continued for 25 minutes until Dennis McGuire was pronounced dead (Goode). This execution has renewed an old debate on whether this form of capital punishment violates the Eighth Amendment of the Constitution by way of cruel and unusual punishment. Although many people argue that this technique is the most humane form of execution, it has now reached uncharted territories with the use of untested drugs. In this paper I will argue that lethal injections should be brought to a close because of the ineffectiveness of the new and the old drugs being used, for the fact that executioners are inexperienced, and for the reason that untested drugs are used on inmates. Since lethal injection was first introduced to the United States back in 1977, there have been a total of 1176 inmates executed using this method (Death Penalty Statistics). The most common lethal injection procedure, developed by Dr. Jay Chapman, was at best a combination of three drugs: sodium thiopental (a barbiturate that also has anesthesia), pancuronium bromide (relaxes then paralyses the muscles in the body) and potassium chloride (this drug speeds up the heart until it stops) (Clancy, O’Brien 278). Many advocates believe that lethal injection......

Injection Moulding

...(i) Injection Molding Demonstration Battenfeld HM 40/130 is the machine used in the laboratory session to mold Polypropylene. Thermoplastic materials such as nylon, polystyrene, polythene and polypropylene can be used in a process called injection molding. How injection molding works? 1. The hopper is filled with granules of plastic powder. The hopper stores the material until it is needed. 2. The heater starts heating up the tube until it reaches a high temperature, then a screw thread starts turning. 3. The granules are pushed along the heater section by a motor, which pushes the granules along the heater section. The heater melts the granules until they reach the liquid state. This liquid is then forced under pressure into a mold where it cools down the liquid and solidifies it, which then turns into a shape. 4. The mold then opens and the ejector pins remove the molded part. In one molding cycle, the maximum amount of plastic injection mold that can be injected is called the “shot size”. For best quality, parts must use about 60% to 70% of a machines rated shot size. Larger shot sizes will not allow sufficient melt cushion for packing. Smaller shot sizes produce greater irregularities and loss of precision. The relatively high melting point of polypropylene allows continued use at 104°C. The resin begins to soften at about 121°C. The polymer “Polypropylene” (C3H6)n properties: Property Value Molecular weight of repeat unit 42.08 g/mol...

No Sql Databases

...recently, Relational database systems have been on the forefront of data storage and management operations. The advent of mobile applications that requires real time analysis like GPS based services, banking and social media has led to huge unstructured data being produced every second. Traditional RDBMS systems have found it difficult to cater to these huge chunks of unstructured data, as RDBMS mainly stores structured data in tabular format. Also, the unstructured data being mapped to a relational database results in increase in complexity as it uses expensive infrastructure to model the same. Also, even if the data model fits into SQL, platter of features provided by SQL becomes an overhead. Relational schema becomes a burden on applications which are trying to store data in multiple forms like videos, blogs and images etc. A new methodology for data management was introduced for the management of unstructured data known as NoSQL (Not Only Structured Query Language). NoSQL covers a broader topic of data structuring, storage and aggregation via various implementation approaches. It can store unstructured data and provide real time analysis to back up the web service applications. It gives up on conventional benchmarking of database management principles like Atomicity, Consistency, Isolation and Durability, to attain flexible data handling. Also, it provides inbuilt data partitioning and replication. Essentially, data across the business domains is governed......

Khi triển khai các ứng dụng web trên Internet, nhiều người vẫn nghĩ rằng việc đảm bảo an toàn, bảo mật nhằm giảm thiểu tối đa khả năng bị tấn công từ các tin tặc chỉ đơn thuần tập trung vào các vấn đề như chọn hệ điều hành, hệ quản trị cơ sở dữ liệu, webserver sẽ chạy ứng dụng, ... mà quên mất rằng ngay cả bản thân ứng dụng chạy trên đó cũng tiềm ẩn một lỗ hổng bảo mật rất lớn. Một trong số các lỗ hổng này đó là SQL injection. Tại Việt Nam, đã qua thời kì các quản trị website lơ là việc quét virus, cập nhật các bản vá lỗi từ các phần mềm hệ thống, nhưng việc chăm sóc các lỗi của các ứng dụng lại rất ít được quan tâm. Đó là lí do tại sao trong thời gian vừa qua, không ít website tại Việt Nam bị tấn công và đa số đều là lỗi SQL injection [1]. Vậy SQL injection là gì ? SQL injection là một kĩ thuật cho phép những kẻ tấn công lợi dụng lỗ hổng trong việc kiểm tra dữ liệu nhập trong các ứng dụng web và các thông báo lỗi của hệ quản trị cơ sở dữ liệu để "tiêm vào" (inject) và thi hành các câu lệnh SQL bất hợp pháp (không được người phát triển ứng dụng lường trước). Hậu quả của nó rất tai hại vì nó cho phép những kẻ tấn công có thể thực hiện các thao tác xóa, hiệu chỉnh, … do có toàn quyền trên cơ sở dữ liệu của ứng dụng, thậm chí là server mà ứng dụng đó đang chạy.

Sql Injection

...SQL injection attacks pose a serious security threat to Web applications or any database-driven site: they allow attackers to obtain unrestricted access to the databases underlying the applications and to the potentially sensitive information these databases contain.These applications accept user inputs and use them to form SQL statements at runtime. During an SQL injection attack, an attacker might provide malicious SQL query segments as user input which could result in a different database request. By using SQL injection attacks, an attacker could thus obtain and/or modify confidential/sensitive information. An attacker could even use a SQL injection vulnerability as a rudimentary IP/Port scanner of the internal corporate network. Several papers in literature have proposed ways to prevent SQL injection attacks in the application layer by examining dynamic SQL query semantics at runtime. Although researchers and practitioners have proposed various methods to address the SQL injection problem, current approaches either fail to address the full scope of the problem or have limitations that prevent their use and adoption. Despite these risks an incredible number of systems on the internet are still susceptible to this form of attack.Many researchers and practitioners are familiar with only a subset of the wide range of techniques available to attackers who are trying to take advantage of SQL injection vulnerabilities. As a consequence, many solutions proposed in the literature......
