CVE-2025-6904
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 · uneditedA vulnerability was found in code-projects Car Rental System 1.0. It has been rated as critical. Affected by this issue is some unknown functionality of the file /admin/add_cars.php. The manipulation of the argument car_name leads to sql injection. The attack may be launched remotely. The exploit has been disclosed to the public 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 · moderate confidenceA SQL injection vulnerability exists in the Car Rental System 1.0 admin interface at /admin/add_cars.php. The car_name parameter is not properly sanitized before use in SQL queries, allowing remote attackers to inject malicious SQL commands. With a CVSS score of 9.8, this critical flaw could allow full database compromise, including data exfiltration, modification, or administrative access.

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 Car Rental System installationLocate the web application directory and check for files like add_cars.php, or check the application banner/version information if availableAffected if The system is running Anisha Car Rental System version 1.0
-
Verify admin interface existsCheck if the file /admin/add_cars.php exists in the web application root directoryAffected if The vulnerable file add_cars.php is present in the /admin/ directory
-
Inspect car_name parameter handlingExamine the source code of add_cars.php and locate the code handling the car_name POST parameter. Check if it is used directly in SQL queries without prepared statements or parameter bindingAffected if The car_name parameter is directly concatenated into SQL queries without sanitization or parameterized queries
-
Review database query constructionSearch the add_cars.php file for SQL query patterns involving car_name. Look for queries like INSERT or UPDATE that include the car_name variable without using mysqli_prepare, PDO prepare, or equivalentAffected if SQL queries involving car_name are constructed using string concatenation instead of prepared statements
The environment is affected if running Car Rental System 1.0 with the /admin/add_cars.php file present and the car_name parameter handled via direct string concatenation in 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 dataImplement prepared statements/parameterized queries for all database operations involving the car_name parameter. Apply input validation and encoding as an additional defense layer. Consider deploying a WAF rule as an interim protective measure until the code fix is deployed.
