Executing manipulation of the argument hdnid can lead to sql injection. The attack can be launched remotely. The exploit has been published and may be used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA SQL injection vulnerability exists in itsourcecode Apartment Management System 1.0 in the /floor/addfloor.php file. The hdnid parameter is not properly sanitized before being used in SQL queries, allowing remote attackers to inject malicious SQL code and potentially exfiltrate sensitive data, escalate privileges, or compromise the database.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Apartment Management System installationLocate the web application's document root directory and identify if the itsourcecode or Admerc Apartment Management System is present. Check for typical paths such as /var/www/html/, /wwwroot/, or the application's known deployment directory.Affected if The application directory contains files consistent with the Apartment Management System
-
Verify the application version is 1.0Check for version indicators such as a version.php file, footer/version information in the application, or any README/install files that specify the version number.Affected if The installed version is exactly 1.0
-
Locate the vulnerable PHP fileNavigate to the /floor/ subdirectory within the application and confirm the presence of addfloor.php.Affected if The file /floor/addfloor.php exists in the application
-
Inspect the hdnid parameter handlingExamine the addfloor.php file source code and locate where the hdnid parameter is used in SQL queries. Look for direct string concatenation or lack of prepared statements around this parameter.Affected if The hdnid parameter is used in SQL queries without parameterized queries or proper sanitization
A system is affected if it runs itsourcecode or Admerc Apartment Management System version 1.0 with the /floor/addfloor.php file present and the hdnid parameter handled in SQL queries without prepared statements.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement parameterized queries (prepared statements) for all database operations involving user input, particularly the hdnid parameter. Apply input validation and consider deploying a Web Application Firewall as an interim control until the code fix is fully deployed.
