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 file /edit_class2.php. It occurs because the 'id' parameter is not properly validated, allowing attackers to inject malicious SQL queries.

An attacker can exploit this flaw remotely without needing to log in or have authorization, which can lead to unauthorized access to the database, data manipulation, and leakage of sensitive information.

Impact Analysis

Exploitation of this vulnerability can have severe impacts including unauthorized database access, data tampering, leakage of sensitive information, and potential full system compromise.

Attackers may gain complete control over the system, disrupt services, and manipulate data without any authentication.

Detection Guidance

This vulnerability can be detected by testing the /edit_class2.php endpoint for SQL injection via the 'id' parameter. One common approach is to send crafted HTTP requests with SQL injection payloads in the 'id' parameter and observe the responses for database errors or unexpected behavior.

  • Use curl or similar tools to send requests with SQL injection payloads, for example: curl "http://targetsite/edit_class2.php?id=1' OR '1'='1"
  • Use automated vulnerability scanners that support SQL injection detection targeting the 'id' parameter on /edit_class2.php.
  • Monitor logs for unusual or malformed requests to /edit_class2.php that include suspicious SQL syntax in the 'id' parameter.
Mitigation Strategies

Immediate mitigation steps include implementing prepared statements with parameter binding to handle the 'id' parameter safely, ensuring strict input validation to reject malicious inputs, and minimizing database user permissions to limit the impact of a potential exploit.

Additionally, conducting regular security audits and monitoring for suspicious activity can help prevent exploitation.
