Fix SQL injection vulnerability in forum.jsp
What is the issue?
The vulnerability is a critical SQL injection flaw in forum.jsp where user input (content, title, user parameters) is directly concatenated into SQL queries using a Statement object. Attackers can inject malicious SQL commands like
' OR '1'='1or); DROP TABLE posts; --through the form inputs to read, modify, or delete database records. This occurs on line 48 where the INSERT statement is constructed without any parameterization or input validation.Why should it be fixed?
SQL injection is a critical OWASP Top 10 vulnerability (CVSS 9.71) that allows attackers to execute arbitrary SQL commands, potentially exposing all user data, credentials, and forum content. Successful exploitation enables unauthorized database access, data theft, data modification, authentication bypass, and complete database destruction. This violates PCI DSS, FISMA, and NIST compliance requirements.
How should it be fixed?
Replace the vulnerable Statement-based SQL execution with a secure PreparedStatement implementation in forum.jsp. Add import for PreparedStatement on line 8. Replace the vulnerable string concatenation pattern on lines 47-48 with parameterized query code that uses placeholders (?,?,?) and setString() methods to bind user inputs as data, not executable SQL. Add proper resource cleanup by calling prepStmt.close(). Create comprehensive security tests in ForumSQLInjectionTest.java covering 13 test cases including OR-based injection, DROP TABLE attacks, UNION-based injection, and legitimate functionality validation to ensure the fix works and prevent regression.
