SQL Injection in CodeAstro Apartment Visitor Management System

Executive Summary

CVE-2026-14797 is a SQL injection vulnerability found in the Apartment Visitor Management System version 1.0, specifically in the file `/apartment-visitor/edit-apartment.php` when handling the `editid` parameter.

The vulnerability occurs because the system does not properly validate input for the `editid` parameter, allowing attackers to inject malicious SQL queries.

This can be exploited remotely and allows attackers to perform unauthorized database access, data leakage, data tampering, system control, and service disruption.

Common attack methods include boolean-based blind, time-based blind, and UNION query SQL injection techniques.

Detection Guidance

This vulnerability can be detected by testing the `editid` parameter in the `/apartment-visitor/edit-apartment.php` endpoint for SQL injection. Common detection methods include sending specially crafted payloads to observe abnormal behavior such as error messages, delays, or unexpected data responses.

• Use boolean-based blind SQL injection payloads to test if the parameter is injectable.
• Use time-based blind SQL injection payloads to detect delays indicating vulnerability.
• Use UNION query payloads to attempt to extract database information.

Example commands using curl or sqlmap could be used to test the vulnerability by injecting SQL payloads into the `editid` parameter.

Mitigation Strategies

Immediate mitigation steps include:

• Implement prepared statements with parameterized queries to prevent SQL injection.
• Validate and sanitize all user inputs, especially the `editid` parameter.
• Minimize database permissions to limit the impact of a potential exploit.
• Conduct regular security audits and code reviews to identify and fix vulnerabilities.

Compliance Impact

The SQL injection vulnerability in the Apartment Visitor Management System can lead to unauthorized database access, data leakage, and data tampering. Such security breaches may result in the exposure or alteration of sensitive personal data, which can negatively impact compliance with data protection regulations like GDPR and HIPAA that require safeguarding personal and health information.

Failure to protect against such vulnerabilities could lead to violations of confidentiality, integrity, and availability principles mandated by these standards, potentially resulting in legal penalties, loss of trust, and other compliance issues.
