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_subject.php file where the 'ID' parameter is not properly validated. Attackers can inject malicious SQL code through this parameter to manipulate the database without authentication.

Detection Guidance

To detect this SQL injection vulnerability in the Class and Exam Timetabling System, you can use tools like SQLmap to test the /edit_subject.php endpoint for SQL injection flaws. Example command: sqlmap -u "http://target-site/edit_subject.php?id=1" --batch. You can also manually test with payloads like ' OR 1=1 -- or by sending requests with varying id values to observe database errors or unexpected responses.

  • Use automated tools such as SQLmap to scan for SQL injection vulnerabilities in the /edit_subject.php file.
  • Manually test by injecting SQL payloads into the 'id' parameter and monitor for errors or unusual behavior.
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 complete system compromise. Attackers could also use it to bypass authentication or execute administrative operations.

Compliance Impact

This vulnerability likely violates compliance requirements for data protection standards like GDPR and HIPAA, which mandate strict controls to prevent unauthorized data access or leaks. Exploitation could result in data breaches, leading to legal penalties and reputational damage.

Mitigation Strategies

Immediately implement prepared statements with parameter binding for all database queries involving user input. Validate and sanitize all inputs, especially the 'id' parameter in /edit_subject.php. Restrict database user permissions to the minimum required. Conduct a security audit to identify other potential vulnerabilities.

  • Apply prepared statements with parameter binding to prevent SQL injection in the 'id' parameter.
  • Enforce strict input validation and sanitization for all user-supplied data.
  • Limit database user permissions to reduce potential damage from exploitation.
