CWE ID Description
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.
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.

Executive Summary

This vulnerability is a SQL injection flaw found in the Class and Exam Timetabling System version 1.0, specifically in the /edit_product.php file. It occurs because the 'id' parameter is not properly validated, allowing an attacker to manipulate it to inject malicious SQL queries remotely without needing authentication.

Such injection can be exploited using various techniques like boolean-based blind, error-based, time-based blind, and UNION query attacks.

Impact Analysis

Exploitation of this vulnerability can lead to unauthorized access to the database, allowing attackers to view, modify, or delete sensitive data.

It can result in data tampering, leakage of sensitive information, and potentially full system compromise.

Detection Guidance

This SQL injection vulnerability in the /edit_product.php file can be detected by testing the 'id' parameter for SQL injection flaws. Common detection methods include sending crafted inputs to the 'id' parameter and observing the application's response for anomalies such as database errors, time delays, or unexpected data.

  • Use sqlmap or similar automated tools targeting the 'id' parameter in the /edit_product.php endpoint to detect SQL injection.
  • Manually test with payloads such as ' OR 1=1-- or ' UNION SELECT NULL-- to check for error-based or UNION query injection.
  • Use time-based blind SQL injection payloads like ' OR SLEEP(5)-- to detect time delays indicating vulnerability.
  • Example command using sqlmap: sqlmap -u "http://targetsite/edit_product.php?id=1" --batch --risk=3 --level=5
Mitigation Strategies

Immediate mitigation steps include applying input validation and sanitization on the 'id' parameter to prevent malicious SQL code from being executed.

  • Implement prepared statements (parameterized queries) in the /edit_product.php file to safely handle user inputs.
  • Minimize database user permissions to limit the impact of a potential SQL injection attack.
  • Conduct regular security audits and code reviews focusing on input handling and database queries.
  • If possible, apply patches or updates provided by the software vendor addressing this vulnerability.
Compliance Impact

This SQL injection vulnerability allows unauthorized access to the database, which can lead to data tampering and sensitive information leakage.

Such unauthorized access and potential data breaches can negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require protection of personal and sensitive data.

Failure to secure the system against this vulnerability may result in violations of data protection requirements, leading to legal and financial consequences.
