Sqlmap is included in pen testing linux distros like kali linux, backtrack, backbox etc. On other distros it can be simply downloaded from the following url.Since its written in python, first you have to install python on your system. On ubuntu install python from synaptic. On windows install activestate python. Check out this post for details on how to.For the list of options and parameters that can be used with the sqlmap command, check the sqlmap documentation atIn this tutorial we are going to learn how to use sqlmap to exploit a vulnerable web application and see what all can be done with such a tool.To understand this tutorial you should have thorough knowledge of how database driven web applications work. For example those made with php+mysql. Vulnerable UrlsLets say there is a web application or website that has a url in it like this it is prone to sql injection because the developer of that site did not properly escape the parameter id.
This can be simply tested by trying to open the url just added a single quote in the parameter. If this url throws an error or reacts in an unexpected manner then it is clear that the database has got the unexpected single quote which the application did not escape properly.
So in this case this input parameter 'id' is vulnerable to sql injection. Hacking with sqlmapNow its time to move on to sqlmap to hack such urls. The sqlmap command is run from the terminal with the python interpreter. Python sqlmap.py -u 'above is the first and most simple command to run with the sqlmap tool.
It checks the input parameters to find if they are vulnerable to sql injection or not. For this sqlmap sends different kinds of sql injection payloads to the input parameter and checks the output. In the process sqlmap is also able to identify the remote system os, database name and version.
It is possible to run arbitrary commands on the database server's underlying operating system when the back-end database management system is either MySQL, PostgreSQL or Microsoft SQL Server, and the session user has the needed privileges to abuse database specific functionalities and architectural weaknesses.The most important privilege needed by the current database user is to write files through the database functions. This is absent in most cases. Hence this technique will not work in most cases. Sometimes sqlmap is unable to connect to the url at all. This is visible when it gets stuck at the first task of 'testing connection to the target url'.
In such cases its helpful to use the '-random-agent' option. This makes sqlmap to use a valid user agent signature like the ones send by a browser like chrome or firefox.2.
For urls that are not in the form of param=value sqlmap cannot automatically know where to inject. For example mvc urls like such cases sqlmap needs to be told the injection point marked by a. above will tell sqlmap to inject at the point marked by.3.
When using forms that submit data through post method then sqlmap has to be provided the post data in the '-data' options. For more information check out this.
SQL injection – one of the most critical vulnerabilities till now – is still included in the list’s Injection flaws section. SQLMap is a tool that helps penetration testers prove that SQL injection is one the most critical vulnerabilities present in enterprise security.‘SQLMap’is a simple python based tool to exploit SQL injection vulnerabilities to the level where it raises eyebrows becausethis tool can be used:. To scan web application for SQL injection vulnerability. To exploit SQL injection vulnerability.
To extract the database and database user details completely. To bypass a Web Application Firewall (WAF) using tamper scripts. To own the underlying operating system i.e. Gain the operating system access and run OS level commands.Pre-requisites and Installation. For using this tool all you need to know is basics of SQL Injection, how and why it occurs.
Once your SQL Injection detection is done, you need a direction as to what you want to perform while exploiting the target. Command - C: sqlmap & gt; python sqlmap. Cookie = 'security=low; PHPSESSID=e8495b455c5ef26c415ab480425135ee'Command Explained:–url: The vulnerable application’s URL–cookie: Session cookie to maintain access while attackingOutput:Figure 1: SQLMap confirming SQL injection and enumerating application detailsAnalysis: By looking at the output given by SQLMap we can conclude following points:. The application is vulnerable to SQL injection.
Type of SQL injection – UNION query. Back-end DBMS – MySQL 5. Technology Details – Linux Ubuntu 8.04, PHP 5.2.4, Apache 2.2.8. Enumerating Database Names: Is SQL injection present? Now, moving to step 2, check for what all databases we can enumerate out of the application.Command:.

Enumerating a database table names – (Database – dvwa)Database names – check!
Select a specific database and enumerate the table names present in that database.NOTE: You are too lazy to perform all the steps and provided you have enough of time, then you can simply use “–dump-all” option to dump entire database.Command:.

Py - r Sorequest. Txt - p & lt; vulnerable parameter & gt;. SQLMap will automatically parse the SOAP request and try to penetrate into the vulnerable parameter./li.
SQLMap and JSON (JavaScript Object Notation) request: On similar lines of use of SQLMap for SOAP requests, JSON requests can be parsed and penetrated. For JSON type of request, SQLMap will prompt you a basic question stating that SQLMap has detected JSON type of request in the “request file” and if you’d like to continue? Once you answer yes, the tool will parse the request and go its own way of attacking. SQLMap and Proxy Server: In a typical corporate environment network, you have to deal with lots of approvals for proper network access and internet access. These types of networks are usually secured and monitored using controlled proxy servers for all the traffic coming in or going out.

In such cases, you have an option to add a proxy setting straight to the SQLMap option for communicating to the target URL. Though SQLMap is a command-line tool, it communicates over HTTP protocol hence, if you set a HTTP proxy for respective internet connection, SQLMap would accept it for its work. Py - proxy =” http: //:”. SQLMap On WAF (Web Application Firewall): For additional security, a number of organizations have deployed web application firewalls (WAF). Now, this is a tricky part to exploit such an environment. Here, normal SQL injection attack vectors will not work neither will normal scripts.
A feature called “tamper script” of SQLMap makes our life little easy on WAF front. Few steps to make use of this option are:. Go to SQLMap directory where SQLMap resides. Look for a child directory called “tamper”.

In this directory, there are python scripts to be used. Else you can visit “ for more python scripts to use with tamper option. Just check the names or copy the names of those files for your reference. To verify or check the backend WAF protection in place, “–identify-waf” can be used. If you have found the file online then copy it and save it in SQLMap’s “ tamper” directory. Py & lt; other options & gt; - tamper =” & lt; script - name & gt;.
