How to Prevent

Preventing injection requires keeping data separate from commands and queries:

The preferred option is to use a safe API, which avoids using the interpreter entirely, provides a parameterized interface, or migrates to Object Relational Mapping Tools (ORMs). Note: Even when parameterized, stored procedures can still introduce SQL injection if PL/SQL or T-SQL concatenates queries and data or executes hostile data with EXECUTE IMMEDIATE or exec().

Use positive server-side input validation. This is not a complete defense as many applications require special characters, such as text areas or APIs for mobile applications.

For any residual dynamic queries, escape special characters using the specific escape syntax for that interpreter. (escaping technique) Note: SQL structures such as table names, column names, and so on cannot be escaped, and thus user-supplied structure names are dangerous. This is a common issue in report-writing software.

Use LIMIT and other SQL controls within queries to prevent mass disclosure of records in case of SQL injection.

SQLi Potential Mitigation Measures

Phase: Architecture and Design

Strategy: Libraries or Frameworks

Use a vetted library or framework that prevents this weakness or makes it easier to avoid. For example, persistence layers like Hibernate or Enterprise Java Beans can offer protection against SQL injection when used correctly.

Phase: Architecture and Design

Strategy: Parameterization

Use structured mechanisms that enforce separation between data and code, such as prepared statements, parameterized queries, or stored procedures. Avoid constructing and executing query strings with "exec" to prevent SQL injection [REF-867].

Phases: Architecture and Design; Operation

Strategy: Environment Hardening

Run your code with the minimum privileges necessary for the task [REF-76]. Limit user privileges to prevent unauthorized access if an attack occurs, such as by ensuring database applications don’t run as an administrator.

Phase: Architecture and Design

Duplicate client-side security checks on the server to avoid CWE-602. Attackers can bypass client checks by altering values or removing checks entirely, making server-side validation essential.

Phase: Implementation

Strategy: Output Encoding

Avoid dynamically generating query strings, code, or commands that mix control and data. If unavoidable, use strict allowlists, escape/filter characters, and quote arguments to mitigate risks like SQL injection (CWE-88).

Phase: Implementation

Strategy: Input Validation

Assume all input is malicious. Use strict input validation with allowlists for specifications and reject non-conforming inputs. For SQL queries, limit characters based on parameter expectations for attack prevention.

Phase: Architecture and Design

Strategy: Enforcement by Conversion

For limited sets of acceptable inputs, map fixed values like numeric IDs to filenames or URLs, rejecting anything outside the known set.

Phase: Implementation

Ensure error messages reveal only necessary details, avoiding cryptic language or excessive information. Store sensitive error details in logs but be cautious with content visible to users to prevent revealing internal states.

Phase: Operation

Strategy: Firewall

Use an application firewall to detect attacks against weaknesses in cases where the code can’t be fixed. Firewalls offer defense in depth, though they may require customization and won’t cover all input vectors.

Phases: Operation; Implementation

Strategy: Environment Hardening

In PHP, avoid using register_globals to prevent weaknesses like CWE-95 and CWE-621. Avoid emulating this feature to reduce risks. source
