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 issue found in the Class and Exam Timetabling System version 1.0, specifically in the /edit_course.php file. It occurs because the 'id' parameter is not properly validated, allowing attackers to inject malicious SQL queries remotely without needing authentication.

Exploiting this flaw can enable unauthorized access to the database, manipulation of data, leakage of sensitive information, and potentially compromise the entire system.

Impact Analysis

This vulnerability can have severe impacts including unauthorized access to sensitive data, alteration or deletion of important information, and disruption of services. Attackers can manipulate the database remotely without authentication, which may lead to data breaches, loss of data integrity, and potential system compromise.

Detection Guidance

This vulnerability can be detected by testing the /edit_course.php endpoint for SQL injection via the 'id' parameter. You can attempt to inject SQL payloads into the 'id' argument and observe if the system returns database errors or unexpected behavior.

  • Use curl or similar tools to send requests with SQL injection payloads, for example: curl "http://targetsite/edit_course.php?id=1' OR '1'='1"
  • Use automated vulnerability scanners that support SQL injection detection targeting the 'id' parameter on /edit_course.php.
  • Monitor logs for unusual database errors or suspicious query patterns related to the 'id' parameter.
Mitigation Strategies

Immediate mitigation steps include implementing prepared statements and strict input validation on the 'id' parameter in /edit_course.php to prevent SQL injection.

  • Sanitize and validate all user inputs rigorously before processing.
  • Minimize database permissions to limit the impact of a potential exploit.
  • Conduct regular security audits and code reviews to identify and fix vulnerabilities.
