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 is an authenticated SQL injection vulnerability in the feelcrm-os application version 1.0.0. The issue occurs in the MemberController.class.php file where the group_id parameter is directly inserted into a SQL query without proper validation or sanitization. An attacker with a valid session can manipulate this parameter to inject malicious SQL code, potentially accessing or modifying database contents.

Detection Guidance

To detect this SQL injection vulnerability, monitor error responses from the member list endpoint for malformed SQL syntax or database errors. Use tools like sqlmap to test the group_id parameter with payloads such as group_id=1 AND (SELECT 1 FROM (SELECT(SLEEP(5)))a). Check application logs for unusual database queries or errors indicating SQL injection attempts.

Impact Analysis

An attacker could exploit this to disclose sensitive database information, alter query results affecting member or tenant data, or potentially gain further access depending on database privileges. Successful exploitation requires a valid authenticated session with member list access permissions.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's data protection principles and HIPAA's security requirements for protected health information. Organizations using this software may face compliance violations if sensitive data is exposed through SQL injection.

Mitigation Strategies

Immediately update the MemberController.class.php to use parameterized queries for the group_id parameter. Disable detailed error messages in production to prevent information disclosure. Implement strict input validation for the group_id parameter to ensure it only accepts expected numeric values. Restrict database user permissions to limit potential damage from SQL injection.
