FANo problem! Here’s the information about how SQL Injection works with *OR 1=1* on login pages:
Special thanks to @h4cker_nafeed for the content 🫶🏻
SQL Injection is a remarkable technique celebrated for its effectiveness in exploiting vulnerabilities in web applications.
One common method is using the *OR 1=1’ condition on login pages. This works by manipulating the SQL query that checks user credentials.
For example, if a login form takes a username and password, the application might run a query like this: sql:
SELECT * FROM users WHERE username = ‘user’ AND
password = ‘pass’;
...
If an attacker inputs ‘username’ OR ‘1’=‘1’ as the username and any password, the query becomes: sql
SELECT * FROM users WHERE username = ‘username’ OR
‘1’=‘1’ AND password = ‘pass’;
Since ‘1=1’ is always true, the query returns all rows in the users table, potentially allowing the attacker to bypass authentication and gain access to the system.
Preventing SQL Injection involves using prepared statements, parameterized queries, and proper input validation to ensure user inputs are safely handled.
