Executive Summary

A SQL injection vulnerability was discovered in CodeAstro Apartment Visitor Management System 1.0. The vulnerability affects the login function in the /index.php file and allows remote attackers to manipulate the Username argument to inject malicious SQL. The CVSS score for this vulnerability is 7.3, indicating a high severity level.

Technical Analysis

The vulnerability class is SQL injection, which occurs when user input is not properly sanitized or validated, allowing attackers to inject malicious SQL code. In this case, the attack vector is through the Username argument in the login function of the /index.php file. The root cause is the lack of input validation or sanitization, making it possible for attackers to inject malicious SQL.

How It Gets Exploited

An unauthenticated remote attacker can exploit this vulnerability by sending a crafted request to the /index.php file with a malicious Username argument. For example, an attacker could send a request with a Username parameter that exceeds the expected length or contains malicious SQL code. When the login function processes this request, it fails to validate the input, allowing the attacker to inject malicious SQL. This could lead to unauthorized access to sensitive data or disruption of service.

Impact Assessment

The CodeAstro Apartment Visitor Management System 1.0 is affected by this vulnerability. According to the CVSS score of 7.3, the impact is high, with potential consequences including unauthorized access to sensitive data, disruption of service, or privilege escalation. The attack vector is network-based, and no user interaction is required.

Recommended Actions

To mitigate this vulnerability, users should update CodeAstro Apartment Visitor Management System to a patched version as soon as possible. In the meantime, the following actions can be taken:
  • Implement input validation and sanitization for the Username argument in the login function.
  • Use prepared statements with parameterized queries to prevent SQL injection.
  • Monitor the system for suspicious activity and implement additional security measures to detect and prevent exploitation.
