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.

Executive Summary

This is an SQL injection vulnerability in AppNitro MachForm v30. It exists in the ap_form_{id} parameter, allowing attackers to inject malicious SQL statements. By exploiting this, unauthenticated users can access sensitive database information without proper authorization.

Detection Guidance

To detect this SQL injection vulnerability, monitor HTTP requests targeting grid_datasource.php with unusual parameters like filter[filters][0][field] or ap_form_{id}. Use tools like SQLmap to test for SQLi by sending crafted payloads to these parameters. Check server logs for suspicious SQL error messages or unexpected database queries.

Impact Analysis

An attacker could exploit this to steal, modify, or delete sensitive data stored in the database. This includes user credentials, personal information, or other confidential records. The impact depends on the data stored in the affected application.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR, HIPAA, or other regulations by exposing personal or health data. Organizations may face legal penalties, fines, or reputational damage if sensitive data is compromised due to this flaw.

Mitigation Strategies

Immediately update AppNitro MachForm to the latest patched version. If no patch is available, restrict access to grid_datasource.php via firewall rules or disable it if unused. Implement input validation for all parameters, especially ap_form_{id} and filter[filters][0][field]. Use a web application firewall to block SQL injection attempts.
