Sqlmap Github VERIFIED

sqlmap is an open source penetration testing tool that automates the process of detecting and exploiting SQL injection flaws and taking over of database servers. It comes with a powerful detection engine, many niche features for the ultimate penetration tester and a broad range of switches lasting from database fingerprinting, over data fetching from the database, to accessing the underlying file system and executing commands on the operating system via out-of-band connections.

sqlmap is the result of numerous hours of passionated work from a small team of computer security enthusiasts. If you appreciated our work and you want to see sqlmap kept being developed, please consider making a donation or sponsor our efforts via Sponsor page or via PayPal.

Usage of sqlmap for attacking targets without prior mutual consent is illegal. It is the end user's responsibility to obey all applicable local, state and federal laws. Developers assume no liability and are not responsible for any misuse or damage caused by this program.

A reasonable level of verbosity to further understand what sqlmap does under the hood is level 2, primarily for the detection phase and the take-over functionalities. Whereas if you want to see the SQL payloads the tools sends, level 3 is your best choice. This level is also recommended to be used when you feed the developers with a potential bug report, make sure you send along with the standard output the traffic log file generated with option -t.In order to further debug potential bugs or unexpected behaviours, we recommend you to set the verbosity to level 4 or above. It should be noted that there is also a possibility to set the verbosity by using the shorter version of this option where number of letters v inside the provided switch (instead of option) determines the verbosity level (e.g. -v instead of -v 2, -vv instead of -v 3, -vvv instead of -v 4, etc.)

Even though sqlmap already has capabilities for target crawling, in case that user has other preferences for such task, he can provide the target addresses as a piped-in input directly from some other tool of choice (e.g. waybackurls). It should be noted that links will be automatically parsed from such content, thus there are no constraints for input format.

This option makes sqlmap negotiate with the search engine its session cookie to be able to perform a search, then sqlmap will retrieve Google first 100 results for the Google dork expression with GET parameters asking you if you want to test and inject on each possible affected URL.

sqlmap automatically detects the proper HTTP method to be used in HTTP requests. Nevertheless, in some cases, it is required to force the usage of specific HTTP method (e.g. PUT) that is not used by automatism. This is possible with usage of this option (e.g. --method=PUT).

Note that the HTTP Cookie header values are usually separated by a ; character, not by an &. sqlmap can recognize these as separate sets of parameter=value too, as well as GET and POST parameters. In case that the separation character is other than ; it can be specified by using option --cookie-del.

If at any time during the communication, the web application responds with Set-Cookie headers, sqlmap will automatically use its value in all further HTTP requests as the Cookie header. sqlmap will also automatically test those values for SQL injection. This can be avoided by providing the switch --drop-set-cookie - sqlmap will ignore any coming Set-Cookie header.

Vice versa, if you provide a HTTP Cookie header with option --cookie and the target URL sends an HTTPSet-Cookie header at any time, sqlmap will ask you which set of cookies to use for the following HTTP requests.

Some sites perform a server-side check of HTTP User-Agent header value and fail the HTTP response if a valid User-Agent is not provided, its value is not expected or is blacklisted by a web application firewall or similar intrusion prevention system. In this case sqlmap will show you a message as follows:

It is possible to provide extra HTTP headers by setting the option --headers. Each header must be separated by a newline and it is much easier to provide them from the configuration INI file. You can take a look at the sample sqlmap.conf file for such case.

In case that you want to test the site that occasionally returns HTTP error code that causes problems to regular sqlmap run (e.g. 401 (Unauthorized)), while you want to ignore it and continue on with tests, you can use option --ignore-code

If, for any reason, you need to stay anonymous, instead of passing by a single predefined HTTP(S) proxy server, you can configure a Tor client together with Privoxy (or similar) on your machine as explained in Tor installation guides. Then you can use a switch --tor and sqlmap will try to automatically set Tor proxy connection settings.

You are strongly advised to use --check-tor occasionally to be sure that everything was set up properly. There are cases when Tor bundles (e.g. Vidalia) come misconfigured (or reset previously set configuration) giving you a false sense of anonymity. Using this switch sqlmap will check that everything works as expected by sending a single request to an official Are you using Tor? page before any target requests. In case that check fails, sqlmap will warn you and abruptly exit.

Sometimes web applications or inspection technology in between destroys the session if a certain number of unsuccessful requests is performed. This might occur during the detection phase of sqlmap or when it exploits any of the blind SQL injection types. Reason why is that the SQL payload does not necessarily returns output and might therefore raise a signal to either the application session management or the inspection technology.

Lots of sites incorporate anti-CSRF protection in form of tokens, hidden field values that are randomly set during each page response. sqlmap will automatically try to recognize and bypass that kind of protection, but there are options --csrf-token and --csrf-url that can be used to further fine tune it. Option --csrf-token can be used to set the name of the hidden value that contains the randomized token. This is useful in cases when web sites use non-standard names for such fields. Option --csrf-url can be used for retrieval of the token value from arbitrary URL address. This is useful if the vulnerable target URL doesn't contain the necessary token value in the first place, but it is required to extract it from some other location.

In case that user wants to change (or add new) parameter values, most probably because of some known dependency, he can provide to sqlmap a custom python code with option --eval that will be evaluated just before each request.

There are special HTTP request types which can be used to retrieve HTTP response's size without getting the HTTP body. This knowledge can be used in blind injection technique to distinguish True from False responses. When this switch is provided, sqlmap will try to test and exploit two different NULL connection techniques: Range and HEAD. If any of these is supported by the target web server, speed up will come from the obvious saving of used bandwidth.

This features applies to the brute-force switches and when the data fetching is done through any of the blind SQL injection techniques. For the latter case, sqlmap first calculates the length of the query output in a single thread, then starts the multi-threading. Each thread is assigned to retrieve one character of the query output. The thread ends when that character is retrieved - it takes up to 7 HTTP(S) requests with the bisection algorithm implemented in sqlmap.

By default sqlmap tests all GET parameters and POST parameters. When the value of --level is >= 2 it tests also HTTP Cookie header values. When this value is >= 3 it tests also HTTP User-Agent and HTTP Referer header value for SQL injections. It is however possible to manually specify a comma-separated list of parameter(s) that you want sqlmap to test. This will bypass the dependence on value of --level too.

There are special cases when injection point is within the URI itself. sqlmap does not perform any automatic test against URI paths, unless manually pointed to. You have to specify these injection points in the command line by appending an asterisk (*) (Note: Havij style %INJECT HERE% is also supported) after each URI point that you want sqlmap to test for and exploit a SQL injection.

If for any reason sqlmap fails to detect the back-end DBMS once a SQL injection has been identified or if you want to avoid an active fingeprint, you can provide the name of the back-end DBMS yourself (e.g. postgresql). For MySQL and Microsoft SQL Server provide them respectively in the form MySQL and Microsoft SQL Server , where is a valid version for the DBMS; for instance 5.0 for MySQL and 2005 for Microsoft SQL Server.

Note that this option is not mandatory and it is strongly recommended to use it only if you are absolutely sure about the back-end database management system. If you do not know it, let sqlmap automatically fingerprint it for you.

By default sqlmap automatically detects the web application's back-end database management system underlying operating system when this information is a dependence of any other provided switch or option. At the moment the fully supported operating systems are:

Note that this option is not mandatory and it is strongly recommended to use it only if you are absolutely sure about the back-end database management system underlying operating system. If you do not know it, let sqlmap automatically identify it for you. ff782bc1db
