SQL Injection: Several SQL CVEs

ID

ruby.checksqlcves

Severity

critical

Resource

SQL Injection

Language

Ruby

Description

Improper neutralization of special elements in SQL Commands ('SQL Injection' aka 'SQL').

SQL Injection vulnerabilities are predominant in applications that incorporate user input directly into SQL queries without adequate validation or sanitization. This allows malicious users to inject SQL commands that can alter the functionality of the original query.

By launching an SQL injection attack, threat actors may leak sensitive data from the database, alter data for their profit, delete data for denial of service, extract passwords and other credentials for offline dictionary attacks, or gain access to other systems within the network exploiting trust relationships.

Rationale

Checks for several SQL CVEs

Remediation

To prevent SQL Injection vulnerabilities, the recommended approach is to use parameterized queries. These structures inherently separate SQL code from data input, neutralizing the potential for input to alter query logic maliciously.

Furthermore, consider these additional precautions:

  • Implement strong input validation and sanitization to enforce expected data patterns and strip potentially harmful characters.

  • Utilize ORM frameworks that abstract direct SQL query writing, inherently minimizing the risk of injection vulnerabilities.

  • Regularly conduct security testing, including SAST reviews, to detect and address potential vulnerabilities early in the development lifecycle.

  • Educate development teams on secure coding practices to integrate security awareness into the development culture.
