Description: Vulnerability Information AppSecAI Vulnerability ID: 69654fbefc355c4beda09b6f Vulnerability: SQL Injection CWE Classification: CWE-89 Severity: Medium File: src/main/java/org/owasp/benchmark/testcode/BenchmarkTest02534.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: 98% Analysis The code contains a classic SQL injection vulnerability at line 55. User input from request.getParameterValues() flows through doSomething() (which performs no sanitization) into the 'bar' variable, which is then directly concatenated into the SQL query string: "SELECT * from USERS where USERNAME=? and PASSWORD='" + bar + "'". While the code uses PreparedStatement (good practice), it defeats the protection by constructing the SQL string with concatenation BEFORE passing it to prepareStatement(). The parameterized placeholder (?) only protects the USERNAME field; the PASSWORD field uses unsafe string concatenation. An attacker can inject SQL via the bar variable (e.g., input "' OR '1'='1" would bypass authentication). The security guideline about SeparateClassRequest.getTheValue returning sanitized values is irrelevant here since this code uses request.getParameterValues() directly. Recommended Remediation Replace string concatenation with proper parameterization. Change line 55 to: "SELECT * from USERS where USERNAME=? and PASSWORD=?" and add statement.setString(2, bar); after line 64 to bind the bar variable as a parameter instead of concatenating it into the SQL string. Remediation Details Fix Description: Summary Fixed the SQL injection vulnerability in BenchmarkTest02534.java by replacing string concatenation with parameterized queries. Changes Made: Line 50: Changed SQL query from "SELECT * from USERS where USERNAME=? and PASSWORD='" + bar + "'" to "SELECT * from USERS where USERNAME=? and PASSWORD=?" Line 62: Added statement.setString(2, bar); to bind the PASSWORD parameter bug_fix_explanation: The code concatenated user input (bar) directly into the SQL query for the PASSWORD field, creating a SQL injection vulnerability. An attacker could manipulate the bar variable to inject malicious SQL commands (e.g., ' OR '1'='1 to bypass authentication or '; DROP TABLE USERS; -- to execute destructive operations). Fixed by converting the PASSWORD field to use a parameterized query placeholder (?) and binding the user input via statement.setString(2, bar). Parameterized queries treat user input as data rather than executable SQL code, preventing injection attacks. The JDBC driver automatically escapes special characters and ensures the input is safely incorporated into the query. This approach is secure and maintainable because it leverages the database driver's built-in protection mechanisms and follows OWASP recommendations for preventing SQL injection vulnerabilities. Changes Made: Updated source code with secure implementation This PR was generated automatically to address a security vulnerability. Please review the changes carefully before merging.
