SQL Injection (SQLi) is a type of an injection attack that makes it possible to execute malicious SQL statements. These statements control a database server behind a web application. Attackers can use SQL Injection vulnerabilities to bypass application security measures. They can go around ...
An SQL injection (SQLi) is a type of attack in which cyber criminals attempt to exploit vulnerabilities in an application's code by inserting an SQL query into regular input or form fields, such as a username or password. The SQL statement is then passed to the application's underlying SQL...

Use Parameters with Dynamic SQL Additional Considerations Additional ResourcesObjectivesLearn how SQL injection attacks work. Constrain input to prevent SQL injection. Use type safe SQL command parameters to prevent SQL inject...
In a time-based blind SQL injection attack, threat actors can determine whether a query’s result is true or false by forcing the dataset to wait for a number of seconds before responding. Both of these are sometimes referred to as inferential SQL injection attacks, since no data is returned...
How to prevent SQL injection attacks on your site? The best way to handle malware and exploits is to prevent them from happening. To protect your website from SQL injection attacks, follow these steps to ensure maximum security: Use a firewall:Firewalls are your best defense against SQL injec...
There are many ways to explain SQL Injection, and the "best" way is clearly determined by who you’re talking to. For somewhat technical folks, I like my friend Steve’s explanation, I use the explanation below. Two Key Concepts SQL Injection is a computer security vulnerability where two...
SQL injection is one of the most common types of injection attack. To carry it out, an attacker provides malicious SQL statements through the application. These control the backend database server. SQL injection is independent of the technology used for the underlying application. Thus, this attac...
EXEC sys.sp_executesql @SQL; END; Normally I’d raise hell about someone using a function like STRING_SPLIT in a where clause, but for simple DMV queries you’re not likely to see a significant perf hit. There’s a lot of stuff you’ll see in DMV queries that are not okay in nor...
dynamic SQL statements with user input in parts of the SQL that aren't parameterizable, we need to exercise a great deal of caution in many places in the codebase. If we're sloppy in just one of those places, we can wind up leaving the door open to future SQL injection. It would...
What is a SQL injection vulnerability? Most useful WordPress plugins have some kind of interaction with the database. User input is frequently sent to the database, either because it needs to be stored in the DB, it needs to modify something in the DB, or because it is being used as pa...
