Vulnerability Information

AppSecAI Vulnerability ID: 6914fa3928b9e848644fcea5
Vulnerability: SQL Injection
CWE Classification: CWE-89
Severity: Medium
File: src/main/java/org/owasp/benchmark/testcode/BenchmarkTest01011.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

Classic SQL injection vulnerability. User-controlled cookie value flows through URLDecoder.decode() (line 64) → doSomething() method (line 70) → string concatenation in SQL query (line 72) → Statement.executeBatch() (line 76). No sanitization or parameterization exists. The security guideline about SeparateClassRequest.getTheValue() is irrelevant here—code directly extracts cookie values via request.getCookies(). Attacker-controlled cookie payload like ') OR '1'='1-- would bypass authentication.

Recommended Remediation

Replace string concatenation with PreparedStatement parameterization. Change line 72 to use placeholders: 'SELECT * from USERS where USERNAME=? and PASSWORD=?' and bind 'foo' and bar as parameters via statement.setString(). This prevents injected SQL metacharacters from altering query structure.

Remediation Details

Fix Description:

Fix Complete

Fixed the SQL injection vulnerability in BenchmarkTest01011.java:67-74 by replacing string concatenation with parameterized queries.

What was vulnerable:
The code concatenated user input directly into a SQL query string, allowing attackers to inject malicious SQL through the cookie value. For example, a cookie value of ' OR '1'='1 would bypass authentication.

How the fix works:
Replaced Statement with PreparedStatement and parameterized queries. The placeholder ? in the SQL string is bound to the user input using setString(), which treats the input as data rather than executable SQL code. The database driver automatically escapes special characters, preventing SQL injection attacks regardless of the input content.

Why this approach is secure:

• User input cannot alter the SQL query structure
• All special characters are properly escaped by the JDBC driver
• Attackers cannot break out of the parameter context to inject commands
• The fix follows OWASP guidelines for SQL injection prevention
• Maintains identical functionality while eliminating the vulnerability

No migration steps required. The change is backward compatible and requires no configuration updates or database schema modifications.

Changes Made:

• Updated source code with secure implementation
