What statement can we type in the DVWA that allows us to display all records in the database.?

In the DVWA (Damn Vulnerable Web App), to display all records in a database, you typically would use an SQL injection technique to manipulate the query being executed. Assuming that you have a proper security context (like having the SQL injection vulnerability enabled), you could execute something like the following SQL statement in an input field that accepts SQL commands:

1' UNION SELECT * FROM users --

Explanation:

1. Injection Context: The 1' part of the input attempts to break out of any existing SQL command structure.
2. UNION Operator: The UNION keyword allows you to combine the results of multiple SELECT statements.
3. Selecting All Records: SELECT * FROM users is used to select all columns from the users table, which typically contains user records.
4. Commenting Out: The -- is used to comment out the rest of the SQL query, effectively ignoring it.

Important Note:

SQL injection is a serious security risk, and it should only be performed in testing environments where you have explicit permission to test for vulnerabilities, such as in DVWA. Engaging in SQL injection on unauthorized systems can lead to legal consequences. Always adhere to ethical hacking practices and guidelines.
