Vulnerability Information

AppSecAI Vulnerability ID: 69654fbffc355c4beda09b73
Vulnerability: SQL Injection
CWE Classification: CWE-89
Severity: Medium
File: src/main/java/org/owasp/benchmark/testcode/BenchmarkTest02642.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.

Status: Confirmed vulnerability
Security Assessment:

Severity: Critical

Confidence: 95%

Analysis

User input from query parameter 'BenchmarkTest02642' flows through URLDecoder.decode() → doSomething() → direct string concatenation into SQL query at line 69. The SQL statement uses string concatenation ("SELECT * from USERS where USERNAME='foo' and PASSWORD='" + bar + "'"), not parameterized queries. No sanitization is visible in the data flow path. An attacker can inject SQL payloads (e.g., ' OR '1'='1'--) to manipulate the query logic. The transformation via ThingInterface.doSomething() is opaque and doesn't indicate sanitization. This is a textbook SQL injection vulnerability pattern.

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);. This ensures user input is treated as data, not executable SQL code. Alternatively, use Spring's JdbcTemplate with named parameters: jdbcTemplate.queryForList("SELECT * FROM USERS WHERE USERNAME='foo' AND PASSWORD=:password", Collections.singletonMap("password", bar)).

Fix Summary

Fixed the SQL injection vulnerability by replacing string concatenation with a parameterized query. The original code directly concatenated user input (bar) into the SQL statement:

String sql = "SELECT * from USERS where USERNAME='foo' and PASSWORD='" + bar + "'";

This allows attackers to inject malicious SQL by manipulating the bar value (e.g., ' OR '1'='1).

The fix uses Spring JDBCTemplate's parameterized query support:

String sql = "SELECT * from USERS where USERNAME='foo' and PASSWORD=?";
org.owasp.benchmark.helpers.DatabaseHelper.JDBCtemplate.queryForList(sql, bar);

The ? placeholder ensures that bar is treated as data rather than executable SQL code. JDBCTemplate automatically escapes and sanitizes the parameter, preventing SQL injection attacks while maintaining identical functionality.

No migration steps required. This is a drop-in replacement that:

• Preserves existing behavior and API compatibility
• Requires no configuration changes
• Works with the existing Spring JDBCTemplate dependency
• Maintains the same query results and error handling

Changes Made:

• Updated source code with secure implementation
