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 CodeAstro AVMS installationLocate the application web root directory and look for the CodeAstro Apartment Visitor Management System files. Common paths include /var/www/html/, /www/, or C:\inetpub\wwwroot\. Look for the presence of index.php and related application files.Affected if The CodeAstro Apartment Visitor Management System application files are present on the server
-
Verify application version is 1.0Check for version indicators such as a version.php file, a readme.txt, or a meta tag in the source code that displays the version number. Compare the installed version against the affected range (1.0).Affected if The installed version is CodeAstro Apartment Visitor Management System 1.0
-
Locate vulnerable login fileVerify that /index.php exists in the web root of the application. This is the file containing the login form with the vulnerable Username parameter.Affected if The file /index.php exists in the web-accessible directory
-
Confirm login form is accessibleAccess the application URL and verify the login form at /index.php is reachable. This can be done by visiting the application's base URL in a browser or using a tool like curl to confirm HTTP 200 response.Affected if The login form at /index.php is accessible over the network (not restricted by authentication or network controls)
-
Inspect Username parameter handlingReview the source code of /index.php and locate the PHP code handling the Username parameter from the login form. Look for direct insertion of the username variable into SQL queries without using prepared statements or proper sanitization functions.Affected if The code shows direct use of the username input in SQL queries without parameterized queries or input sanitization
The environment is affected if CodeAstro Apartment Visitor Management System version 1.0 is installed with the /index.php login form accessible and the Username parameter handled without prepared statements in the SQL queries.

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 dataReplace dynamic SQL queries with parameterized queries/prepared statements in the login component. Validate and sanitize all user inputs before using them in database queries.
