CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

This vulnerability is a time-based blind SQL injection in the Online Shopping System 1.0. It affects the search functionality via the keyword parameter in the POST request to /action.php. Attackers can inject malicious SQL commands, such as MySQL's SLEEP(20) function, causing a 20-second delay in database responses to confirm successful injection. The flaw stems from improper handling of user input in SQL queries, allowing remote attackers to extract sensitive data without authentication.

Detection Guidance

To detect time-based blind SQL injection in the Online Shopping System, test the /action.php endpoint with POST requests containing the keyword parameter. Inject SQL time delays like SLEEP(20) and observe if the response is delayed by 20 seconds. Use tools like curl or Burp Suite to send crafted requests such as: curl -X POST -d 'keyword=test AND SLEEP(20)' http://target/action.php. Monitor response times for anomalies.

Check application logs for unusual SQL query patterns or errors. Automated scanners like SQLmap can also test for this vulnerability by sending payloads and analyzing delays or errors in responses.

Impact Analysis

This vulnerability could expose sensitive data like user records, administrator details, password hashes, customer information, order data, product details, and internal database structure. Attackers can exploit it remotely without authentication, potentially leading to data breaches, identity theft, or unauthorized system access.

Compliance Impact

This vulnerability likely violates GDPR and HIPAA by enabling unauthorized access to sensitive personal and health data. GDPR requires protecting personal data, while HIPAA mandates safeguarding health information. A breach could result in legal penalties, fines, and reputational damage due to non-compliance with these regulations.

Mitigation Strategies

Immediately update the application to use parameterized queries instead of string concatenation for SQL queries. Implement strict server-side input validation to sanitize the keyword parameter. Restrict database user permissions to limit access to sensitive data. Disable detailed SQL error messages to prevent information leakage.

Monitor network traffic for suspicious POST requests to /action.php. Consider deploying a web application firewall (WAF) to block SQL injection attempts. Apply patches or updates provided by the vendor if available.
