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 found in the CodeAstro Leave Management System version 1.0, specifically in the file /admin/delete_leave_type.php. It occurs because the 'leave_type' parameter is not properly validated, allowing an attacker to inject malicious SQL queries into the database.

An attacker can exploit this flaw remotely to manipulate the database, potentially accessing or altering sensitive data.

Impact Analysis

Exploiting this SQL injection vulnerability can lead to unauthorized access to sensitive information, data tampering, and possible full system compromise.

  • Access to confidential data stored in the database.
  • Modification or deletion of critical data.
  • Potential disruption of system operations.
Detection Guidance

This SQL injection vulnerability can be detected by testing the 'leave_type' parameter in the /admin/delete_leave_type.php endpoint for SQL injection flaws.

A proof-of-concept involves a time-based blind SQL injection attack using the 'leave_type' parameter.

  • Use curl or similar tools to send crafted payloads to the vulnerable parameter and observe response delays or errors.
  • Example command to test for time-based blind SQL injection: curl -X GET "http://targetsite/admin/delete_leave_type.php?leave_type=1' AND IF(SLEEP(5),1,0)-- "
  • Monitor network traffic for unusual or suspicious SQL queries targeting the 'leave_type' parameter.
Mitigation Strategies

Immediate mitigation steps include:

  • Implement prepared statements with parameter binding to prevent SQL injection.
  • Apply strict input validation on the 'leave_type' parameter to allow only expected values.
  • Minimize database user permissions to limit the impact of a potential injection.
  • Conduct regular security audits and code reviews focusing on input handling.

Additionally, consider temporarily restricting access to the vulnerable endpoint until a patch is applied.

Compliance Impact

The SQL injection vulnerability in the CodeAstro Leave Management System allows unauthorized access to sensitive data and potential data tampering. Such unauthorized access and data integrity issues can lead to non-compliance with data protection regulations like GDPR and HIPAA, which require safeguarding personal and sensitive information against unauthorized access and ensuring data integrity.

Failure to address this vulnerability could result in breaches of confidentiality and integrity of personal data, potentially leading to regulatory penalties and loss of trust.
