Description
Blind SQL Injection is a type of attack where malicious SQL queries are inserted into input data, allowing attackers to manipulate the database without directly observing the results of their actions. Successful exploitation can lead to data theft, modification of database records, unauthorized access, and even control over the entire database management system (DBMS).
Recommendation
To prevent Blind SQL Injection attacks, developers should use prepared statements or parameterized queries instead of concatenating user input into SQL queries directly. If prepared statements are not feasible, ensure proper input validation and sanitization. Employ whitelists to restrict user input wherever possible. Additionally, consider implementing comprehensive logging and monitoring to detect and respond to potential SQL injection attempts.
