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 /edit_teacher.php file where an attacker can manipulate the ID argument to execute arbitrary SQL commands. The attack can be performed remotely and has been publicly disclosed.

Detection Guidance

To detect SQL injection vulnerabilities in the Class and Exam Timetabling System, inspect the /edit_teacher.php file for improper input handling. Check for user-supplied input in the ID parameter without proper sanitization. Use tools like SQLmap to test for SQL injection by sending crafted payloads to the parameter.

Impact Analysis

An attacker could exploit this to access, modify, or delete sensitive data in the database. This may lead to unauthorized data exposure, data corruption, or loss of system integrity. The remote nature of the attack increases the risk of exploitation.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR or HIPAA if it results in unauthorized access to personal or health data. Both regulations require protection against SQL injection and unauthorized data access, which this flaw undermines.

Mitigation Strategies

Immediately update the application to the latest patched version if available. Implement input validation for the ID parameter in /edit_teacher.php to reject non-numeric values. Use prepared statements with parameterized queries for all database interactions. Restrict database user permissions to limit potential damage from SQL injection.
