As we saw, it is not working with suffixes. The original test was using the tag as a sub-tag of the tag. This test simply forces the use of the # character (MySQL comment) in every payload. Here is my new test I added to my payload.xml file: AND boolean-based blind - WHERE or HAVING clause (Forced MySQL comment) 1 1 1 1 1 AND # AND = # AND = # MySQL As this is a boolean-based blind SQLi instance, I am using the test called 'AND boolean-based blind - WHERE or HAVING clause (MySQL comment)' as a template and modifying it. It is an XML file and you can add your proper tests to it. The file located at 'sqlmap/xml/payloads.xml' contains all the tests sqlmap will perform. Obviously, it is not working.Д«elow is how you should handle this situation. So every query looks like this: id=1' AND 1=0 -BR. It appears sqlmap does not add comments when a suffix is passed to the command line. To check what's going on, we can increase the debug level or set the -proxy=' option to point to your favorite web proxy. Let's try it with debug information (-v3 option). It will force sqlmap to add this value after every query. Well, the first idea is to use the -suffix option with the value '-BR' and set 'id=1' in the query. The decoded string is: id=1' AND 1=1 #-BR Sqlmap Tweaking Note that we are URL-encoding special characters because the parameter is located in the URL. For more information about this kind of SQLi, please check this link. This is a typical Blind SQL Injection instance and I'm lazy, so I don't want to exploit it manually. To pass the validation and successfully exploit this SQLi, we must inject our payload between the numerical value and the '-BR' suffix. Even when I set the level and risk of tests to their maximum, sqlmap is not able to find it: I'm also forcing sqlmap to test the 'id' parameter with the -p option. I'm using a valid User-Agent and an authenticated Session Cookie. sqlmap.py -headers='User-Agent: Mozilla/5.0 (X11 Ubuntu Linux i686 rv:25.0) Gecko/20100101 Firefox/25.0' -cookie='security=low PHPSESSID=oikbs8qcic2omf5gnd09kihsm7' -u ' -level=5 risk=3 -p id This page is clearly vulnerable to SQL Injection but due to the string manipulation routine before the actual SQL command, sqlmap is unable to find it. Then, it concatenates this value to the SQL query used to check if it is a valid user ID and returns the result ('User exists!'or 'Unknown user!'): The application will first validate whether this string is present and will extract the numerical value.

Here is the source of the php file responsible for the Blind SQL Injection exercise located at //dvwa/vulnerabilities/sqli_blind/source/low.php: Wrong ID format' else ?>Д«asically, this code will receive an ID compounded of a numerical value followed by the string '-BR'. I also customized the source code to simulate a complex injection point. In this example, I will use the Damn Vulnerable Web App ( ), a deliberately insecure web application used for educational purposes. Sometimes sqlmap cannot find tricky injection points and some configuration tweaks are needed. Finally, the -cookie option is used to specify any useful Cookie along with the queries (e.g. To maximize successful detection and exploitation, I usually use the -headers option to pass a valid User-Agent header (from my browser for example). You can use the -data option to pass any POST parameters. This is useful when the query contains various parameters, and you don't want sqlmap to test everyting. You can also explicitly tell sqlmap to only test specific parameters with the -p option.

Sqlmap will run a series of tests and detect it very quickly. The target URL after the -u option includes a parameter vulnerable to SQLi (vulnparam). Using sqlmap for classic SQLi is very straightforward.

I normally use it for exploitation only because I prefer manual detection in order to avoid stressing the web server or being blocked by IPS/WAF devices.Д«elow I provide a basic overview of sqlmap and some configuration tweaks for finding trickier injection points. Sqlmap is an awesome tool that automates SQL Injection discovery and exploitation processes.
