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

CVE-2026-14640 is a SQL injection vulnerability found in the Apartment Visitor Management System version 1.0, specifically in the /index.php file related to the Login component.

The vulnerability occurs due to insufficient input validation of the 'username' parameter, which allows an attacker to manipulate this argument to inject malicious SQL queries.

This flaw can be exploited remotely without any authentication, enabling attackers to execute unauthorized database commands.

Impact Analysis

This vulnerability can have serious impacts including unauthorized access to the database, data tampering, leakage of sensitive information, and potential full system compromise.

Attackers can exploit this vulnerability remotely to execute arbitrary SQL commands, which may lead to loss of data integrity, confidentiality, and availability.

Detection Guidance

This vulnerability can be detected by testing the 'username' parameter in the '/apartment-visitor/index.php' file for SQL injection weaknesses.

Tools like sqlmap can be used to automate detection by sending time-based blind SQL injection payloads targeting the 'username' parameter.

  • Example sqlmap command: sqlmap -u "http://target/apartment-visitor/index.php" --data="username=admin&password=pass" -p username --technique=T --risk=3 --level=5
Mitigation Strategies

Immediate remediation steps include implementing prepared statements and strict input validation on the 'username' parameter to prevent SQL injection.

Additionally, minimize database permissions to limit the impact of a potential exploit and conduct regular security audits to identify and fix vulnerabilities.
