Multi-Agent Code Vulnerability Detection & Exploit Verification

programming_language: Python code_snippet: def login(username, password): query = "SELECT * FROM users WHERE username='" + username + "' AND password='" + password + "'" cursor.execute(query) return cursor.fetchone() def upload_file(filename, content): filepath = "/uploads/" + filename with open(filepath, 'w') as f: f.write(content) vulnerability_databases: CVE, NVD, OWASP application_context: Web application with file upload functionality

## EXECUTIVE SUMMARY - Total vulnerabilities found: 2 - Critical: 1 | High: 1 | Medium: 0 | Low: 0 - Exploitability assessment: Both vulnerabilities are easily exploitable with minimal technical skill required ## DETAILED FINDINGS ### Vulnerability #1: SQL Injection **Type:** CWE-89: SQL Injection **Severity:** Critical **Exploitability Score:** 9/10 **Location:** Line 2 - login function **Description:** Direct string concatenation in SQL query allows attackers to inject malicious SQL commands **Attack Vector:** Attacker can bypass authentication by inputting username: admin'-- and any password **Proof of Concept:** username="admin'--" password="anything" results in query: SELECT * FROM users WHERE username='admin'--' AND password='anything' **Remediation:** Use parameterized queries or prepared statements. Replace with: cursor.execute("SELECT * FROM users WHERE username=? AND password=?", (username, password)) **References:** OWASP SQL Injection Prevention Cheat Sheet ### Vulnerability #2: Path Traversal **Type:** CWE-22: Path Traversal **Severity:** High **Exploitability Score:** 8/10 **Location:** Line 6 - upload_file function **Description:** Unsanitized filename parameter allows directory traversal attacks **Attack Vector:** Attacker can write files outside intended directory using filename like "../../../etc/passwd" **Proof of Concept:** filename="../config.py" could overwrite application configuration **Remediation:** Validate and sanitize filename, use os.path.basename() and implement whitelist of allowed characters **References:** OWASP Path Traversal Attack Prevention ## REMEDIATION PRIORITY 1. Fix SQL Injection (Critical) - Immediate action required (24-48 hours) 2. Fix Path Traversal (High) - Address within 1 week
