Cookie value can be found out using tools like Burp Suite, Web Scarab etc. We need to provide value of cookie set after we have logged in to DVWA. To avoid this, we can use -cookie flag of sqlmap. sqlmap.py -u " This command can be used to test standalone web pages for SQLi, but in our case, because we are testing a page behind a login page, we are redirected to login.php page as we are not authenticated. The type of SQL injection was error-based, an. Web Application (DVWA) is used for demonstrating the. Now, lets check whether this page is vulnerable to SQLi using sqlmap. In this video I demonstrate how to perform basic SQL injections against DVWA (Damn Vulnerable Web Application). SQL injection attack is the most common attack being used by attackers to gain unauthorized access. We can see that, after changing the value for parameter in the URL, different results are obtained. 1) in the text box, result is displayed on the page and the url of the page becomes: Your synthesized query would look like that: SELECT firstname, lastname FROM users WHERE userid 1 or 11- As you can see, the double dash is followed immediately by a which leads to a syntax error as it is not considered a comment.
