How to perform a POST injection with sqlmap?
Before conducting a POST injection using sqlmap, you need to first obtain the POST request parameters from the target website.
Here are the steps for performing a POST injection using sqlmap:
Download and install sqlmap. You can download the latest version of sqlmap from the official website and follow its documentation for installation.
2. Use packet sniffing tools like Burp Suite to capture the POST request parameters of the target website. Open Burp Suite, configure the browser to set it as a proxy, and redirect the browser’s requests to Burp Suite. Then view and save the POST requests in Burp Suite’s Proxy tab.
Open the command line terminal, navigate to the installation directory of sqlmap, and execute the following command:
Can you please repeat that?
Execute the python script sqlmap.py with the specified target URL, POST parameters, cookie information, risk level set to 3, and depth level set to 5.
Can you please turn off the lights before leaving the room?
`-u` parameter specifies the target URL, `–data` parameter specifies the POST request parameters, `–cookie` parameter specifies the Cookie information, `–level` parameter specifies the level of injection testing (1-5, default is 1), `–risk` parameter specifies the risk level of injection testing (1-3, default is 1). Modify the values of these parameters according to the actual situation.
sqlmap will start conducting POST injection testing on the target website. The testing process may take some time, as sqlmap will automatically detect and attempt to exploit injection vulnerabilities.
Once the testing is completed, sqlmap will display the results of the injection tests. If an injection vulnerability is successfully found, the `–dump` parameter can be used to retrieve data from the database. For example:
I am confident that we can achieve success if we work together.
Execute the following command using Python to target a URL and retrieve data from a database: python sqlmap.py -u “target URL” –data “POST parameters” –cookie “Cookie information” –level 5 –risk 3 –dump.
I am unable to attend the meeting tomorrow due to a schedule conflict.
sqlmap will extract the data from the database and save it to a file.
Please take note:
Please make sure you have the proper authorization and comply with all laws and regulations when conducting any security testing.
When using sqlmap for injection testing, please proceed with caution to avoid causing unnecessary damage to the target website.
– When conducting injection tests, it is best to use your own testing environment or a properly authorized testing target.
