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 SQL injection flaw in SourceCodester Class and Exam Timetabling System 1.0. It exists in the mysqli_query function of the file /admin/modal_add_product.php. An attacker can manipulate the fname argument to inject malicious SQL code, allowing remote execution of unauthorized database commands.

Detection Guidance

To detect SQL injection vulnerabilities in the Class and Exam Timetabling System, inspect the /admin/modal_add_product.php file for improper input validation in the fname parameter. Check web server logs for unusual queries or errors related to SQL syntax. Use tools like SQLmap to test for injection points by sending crafted payloads to the fname parameter.

Impact Analysis

This vulnerability allows remote attackers to execute arbitrary SQL commands on the database. This could lead to unauthorized data access, modification, or deletion. Attackers might steal sensitive information like user credentials, exam schedules, or personal data stored in the system.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA by exposing personal or health-related data. GDPR requires protection of personal data, while HIPAA mandates safeguards for health information. A breach could result in legal penalties, fines, and reputational damage.

Mitigation Strategies

Immediately update the application to the latest patched version if available. If not, apply input validation to sanitize the fname parameter in /admin/modal_add_product.php. Use prepared statements with parameterized queries instead of mysqli_query to prevent SQL injection. Restrict database user permissions to limit damage from potential exploits.
