CVE-2022-28110
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 · uneditedHotel Management System v1.0 was discovered to contain a SQL injection vulnerability via the username parameter at the login page.
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 confidenceHotel Management System v1.0 is vulnerable to SQL injection via the username parameter on the login page. An attacker can inject malicious SQL statements through this input to manipulate database queries, potentially bypassing authentication or exfiltrating sensitive data.

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.
-
Identify Hotel Management System installationLocate the Hotel Management System application files on the server or check the deployed web application directory. Look for files typical to this PHP-based application such as login.php, index.php, or admin/ login pages.Affected if The Hotel Management System v1.0 is present on the server or accessible as a web application
-
Verify the installed versionCheck the application version by examining any version file, README, or footer/header in the login page. Common locations include a version.php file, about.php, or the login page source code.Affected if The installed version is exactly 1.0 or the version cannot be determined but the application matches Hotel Management System v1.0
-
Locate the login authentication fileFind the PHP file handling login authentication. Common paths include /login.php, /admin/login.php, or /index.php in the application root. Search for files containing authentication logic and SQL query execution.Affected if A login.php or similar authentication file exists and processes the username parameter through database queries
-
Inspect the username parameter handling in login codeOpen the login authentication file and examine how the username POST/GET parameter is incorporated into SQL queries. Look for direct concatenation of user input into query strings without sanitization or parameter binding.Affected if The code constructs SQL queries by directly inserting the username parameter into the query string (e.g., 'SELECT * FROM users WHERE username = '" . $_POST['username'] . "')
-
Confirm lack of parameterized queriesCheck if prepared statements or parameterized queries (PDO::prepare, mysqli_prepare, or similar) are used for the login query. Search for absence of prepare(), bindParam(), or bindValue() calls in the authentication logic.Affected if The login query does not use parameterized queries and directly includes user input in the SQL statement
You are affected if Hotel Management System v1.0 is deployed and the login authentication code directly incorporates the username parameter into SQL queries without using 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 dataReplace dynamic SQL queries with parameterized queries or prepared statements in the login authentication logic to neutralize SQL injection payloads.
