Description

SQL Injection - SQLite occurs when an application fails to sanitize user inputs in SQLite queries, allowing attackers to insert malicious SQL code. This can lead to unauthorized data access, manipulation, or deletion. Using parameterized queries and validating inputs are crucial to prevent such attacks.

Recommendation

To safeguard against SQL injection attacks, developers must prioritize server-side type checking and employ robust parameterization techniques. This includes utilizing PreparedStatements or CallableStatements in JDBC-based applications, ADO Command Objects with strong type checking in ASP environments, and Stored Procedures with parameterized queries whenever feasible. Furthermore, it is crucial to avoid dynamic query construction through string concatenation, instead opting for data escaping and applying either an ‘allow list’ of approved characters or a ‘deny list’ of disallowed characters in user input. By adhering to the principle of least privilege and utilizing the minimum necessary database access, developers can significantly minimize the impact of SQL injection attacks.
