Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
claudiopizzillo PIAF-HMS (PBX-In-A-Flash Hotel Management System; no released versions, latest commit 389d2633441b65ced1c104212cd62be2bfca21e5) contains multiple unauthenticated SQL injection vulnerabilities. The application has no authentication mechanism and passes user-supplied HTTP parameters directly into deprecated mysql_query calls via string concatenation, without sanitization, escaping, or parameterization.

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 confidence

PIA F-HMS hotel management system contains unauthenticated SQL injection vulnerabilities across multiple PHP files (rooms.php, checkuser.php, ec.php, checkin.php, wakeup.php, bills.php, rates.php, checkout.php). User-supplied HTTP GET/POST parameters are concatenated directly into deprecated mysql_query() calls without sanitization, escaping, or parameterization, allowing remote attackers to inject arbitrary SQL commands.

MitigationReplace all mysql_query() calls with prepared statements using PDO or mysqli, implement proper input validation, and add authentication. The application requires fundamental architecture changes to remediate these critical vulnerabilities.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify PIA F-HMS installation
    Locate the hotel management system web directory and search for the known vulnerable PHP files: rooms.php, checkuser.php, ec.php, checkin.php, wakeup.php, bills.php, rates.php, checkout.php
    Affected if Any of these files exist in the web application directory
  2. Verify deprecated mysql_query usage
    Open each vulnerable PHP file and search for the string 'mysql_query' - the vulnerability stems from use of this deprecated function
    Affected if The code contains mysql_query() calls, indicating the vulnerable code pattern exists
  3. Check for unauthenticated access
    Confirm the vulnerable PHP files are accessible without authentication - the SQL injection is exploitable without login credentials
    Affected if The application does not require authentication to access the affected PHP endpoints
  4. Inspect parameter handling
    Review the PHP source code for direct concatenation of $_GET or $_POST parameters into SQL queries (e.g., $_GET['param'] directly in query string)
    Affected if HTTP parameters are concatenated directly into SQL queries without sanitization or parameter binding
  5. Confirm application is exposed
    Verify the web server serves the PIA F-HMS application endpoints over HTTP/HTTPS - the attack vector is remote via web requests
    Affected if The hotel management system is accessible over the network

A user is affected if PIA F-HMS is installed with any of the vulnerable PHP files present and the deprecated mysql_query() pattern with unsanitized parameter concatenation is in use.
