Vulnerability Information

AppSecAI Vulnerability ID: 69654fbdfc355c4beda09b18
Vulnerability: SQL Injection
CWE Classification: CWE-89
Severity: Medium
File: src/main/java/org/owasp/benchmark/testcode/BenchmarkTest00603.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: 95%

Analysis

Classic SQL injection via string concatenation. User-controlled HTTP parameter name flows through thing.doSomething() directly into SQL statement construction at line 67. The code extracts parameter names from the request (lines 49-62), passes the name to thing.doSomething(), and concatenates the result into SQL without parameterized queries. The security guideline about SeparateClassRequest.getTheValue() doesn't apply here - this code uses ThingInterface.doSomething() with no evidence of sanitization. Exploitable by sending requests with malicious parameter names like 'test' OR '1'='1'.

Recommended Remediation

Replace string concatenation with PreparedStatement parameterized queries: PreparedStatement pstmt = connection.prepareStatement("SELECT * from USERS where USERNAME='foo' and PASSWORD=?"); pstmt.setString(1, bar); ResultSet rs = pstmt.executeQuery();

Remediation Details

Fix Description:

The SQL injection vulnerability has been fixed. Here's what was changed:

Fix Summary

The code concatenated user input directly into a SQL query string, allowing attackers to inject malicious SQL commands. Fixed by replacing string concatenation with a parameterized query using PreparedStatement, which treats user input as data rather than executable SQL.

Changes made:

1. Line 64: Changed SQL query from "SELECT * from USERS where USERNAME='foo' and PASSWORD='" + bar + "'" to "SELECT * from USERS where USERNAME='foo' and PASSWORD=?" (using parameter placeholder)
2. Lines 67-68: Changed from Statement to PreparedStatement
3. Line 69: Added statement.setString(1, bar) to safely bind the user input as a parameter
4. Line 70: Changed statement.execute(sql, ...) to statement.execute() since PreparedStatement already contains the SQL

The parameterized query ensures that the bar variable is treated as a literal string value, not as SQL code. This prevents SQL injection attacks where malicious input like ' OR '1'='1 could manipulate the query logic. The fix maintains complete API compatibility and functional equivalence while eliminating the security vulnerability.
