Vulnerability Information

AppSecAI Vulnerability ID: 69654fbefc355c4beda09b68
Vulnerability: SQL Injection
CWE Classification: CWE-89
Severity: Medium
File: src/main/java/org/owasp/benchmark/testcode/BenchmarkTest02369.java
Detection Rule: java.lang.security.audit.sqli.tainted-sql-from-http-request.tainted-sql-from-http-request
Description: Detected input from a HTTPServletRequest going into a SQL sink or statement. This could lead to SQL injection if variables in the SQL statement are not properly sanitized. Use parameterized SQL queries or properly sanitize user input instead.

Triage Analysis

Status: Confirmed vulnerability
Security Assessment:

Severity: High

Confidence: 100%

Analysis

The code contains a SQL injection vulnerability. User-controlled input from request parameter names flows unsanitized into a SQL INSERT statement via string concatenation at line 65. The attack vector: when iterating through request.getParameterNames(), if a parameter name contains SQL injection payload (e.g., 'malicious'); DROP TABLE users; --') and its value equals 'BenchmarkTest02369', that malicious parameter name is assigned to 'param', passed through doSomething(), and concatenated directly into the SQL query without any sanitization or parameterized query usage.

Recommended Remediation

Replace string concatenation with PreparedStatement parameterized queries. Change line 65-69 to: PreparedStatement pstmt = connection.prepareStatement("INSERT INTO users (username, password) VALUES ('foo', ?)"); pstmt.setString(1, bar); int count = pstmt.executeUpdate(); This ensures user input is treated as data, not executable SQL code.

Remediation Details

Fix Description:

The SQL Injection vulnerability has been fixed. The code previously concatenated user input directly into the SQL query string, allowing attackers to inject malicious SQL commands. Fixed by replacing string concatenation with a parameterized query using PreparedStatement, where the user input is treated as data rather than executable SQL. The setString() method ensures proper escaping and validation of the input parameter, preventing SQL injection attacks while maintaining complete functional equivalence with the original code.
