Vulnerability Information

AppSecAI Vulnerability ID: 69654fbefc355c4beda09b70
Vulnerability: SQL Injection
CWE Classification: CWE-89
Severity: Medium
File: src/main/java/org/owasp/benchmark/testcode/BenchmarkTest02537.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: Critical

Confidence: 100%

Analysis

Unsanitized user input from request.getParameterValues() flows directly into SQL query via string concatenation at line 53. The doSomething() method passes the parameter through without any sanitization (condition at line 75 always evaluates true: 207 > 200). The resulting SQL query concatenates user input into the PASSWORD field, enabling classic SQL injection attacks (e.g., ' OR '1'='1). The security guideline about SeparateClassRequest.getTheValue() does not apply since this code uses the standard HttpServletRequest.getParameterValues() method.

Recommended Remediation

Replace string concatenation with parameterized queries using PreparedStatement: PreparedStatement stmt = connection.prepareStatement("SELECT * from USERS where USERNAME='foo' and PASSWORD=?"); stmt.setString(1, bar); Alternatively, use Spring's JdbcTemplate with named parameters or properly escape user input using a vetted SQL escaping library.

Remediation Details

Fix Description:

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

Security Issue Fixed:
The code concatenated user input directly into a SQL query string, allowing attackers to inject malicious SQL commands. An attacker could submit a password value like ' OR '1'='1 to bypass authentication or '; DROP TABLE USERS; -- to execute destructive commands.

Fix Applied:
Replaced string concatenation with a parameterized query using Spring's JDBCTemplate.update() method:

1. SQL Query: Changed from "... PASSWORD='" + bar + "'" to "... PASSWORD=?" using a placeholder
2. Execution: Changed from batchUpdate(sql) to update(sql, bar) to pass the parameter securely
3. Message: Updated user-facing message to reflect the use of parameterized queries

Why This Is Secure:
Parameterized queries treat user input as data, not executable SQL code. The database driver automatically escapes special characters, preventing injection attacks. The bar variable is passed as a separate parameter and cannot alter the SQL command structure.

Migration Steps:
No migration steps required. This is a drop-in replacement that maintains complete functional compatibility with the original code. The query behavior remains identical for legitimate inputs, but now safely handles malicious input attempts.
