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
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in E4J s.R.L. VikRentCar allows SQL Injection.This issue affects VikRentCar: from n/a through 1.4.0.

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 confidence

SQL injection vulnerability in VikRentCar up to version 1.4.0 allows attackers to inject malicious SQL commands through unsanitized input fields, potentially enabling unauthorized data access, modification, or deletion.

MitigationUpdate to the latest version of VikRentCar (if available) and/or implement parameterized queries and proper input validation across all database interactions.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 VikRentCar version
    Locate the version file in the VikRentCar installation directory (typically named version.php, vikrentcar.php, or similar), or access the admin panel and check the component information page for the installed version number
    Affected if Installed version is 1.4.0 or lower (any version below 1.4.1)
  2. Locate database query files
    Search the VikRentCar installation for PHP files that contain SQL query strings (SELECT, INSERT, UPDATE, DELETE) and database interaction functions, typically found in the main plugin/component folder under models, helpers, or libraries directories
    Affected if Files containing direct SQL queries without evidence of prepared statements or parameterization exist in the installation
  3. Inspect input handling code
    Examine PHP files that process user input (search for $_POST, $_GET, $_REQUEST variables) and verify whether these inputs are used directly in SQL queries without sanitization functions such as $db->quote(), addslashes(), or parameterized queries
    Affected if User-supplied input from $_POST, $_GET, or $_REQUEST is concatenated directly into SQL queries without sanitization or parameter binding
  4. Check vulnerable input fields
    Review forms related to booking, search, vehicle listing, or customer data entry for their handling of input parameters, focusing on fields that accept free-form text and are passed to database queries
    Affected if Text input fields in booking, search, or customer forms transmit unsanitized data to backend SQL queries

You are affected if your VikRentCar installation shows version 1.4.0 or lower and contains PHP code where user input is directly concatenated into SQL queries without sanitization or parameterized queries.

Upgrade available Upgrade to 1.4.1 or later
Fixed in 1.4.1
Interim mitigation

Update to the latest version of VikRentCar (if available) and/or implement parameterized queries and proper input validation across all database interactions.

Recommended fix High confidence

1.4.1

  1. 1. Create a complete backup of the current VikRentCar installation including database and all files
  2. 2. Download VikRentCar version 1.4.1 from the official vendor (E4J s.R.L.)
  3. 3. Upload and extract the new version files to replace the existing installation
  4. 4. Run any provided database migration scripts if included in the 1.4.1 release
  5. 5. Verify the upgrade was successful by checking the admin panel version display
  6. 6. Test critical functionality (booking creation, search, admin operations) to confirm the SQL injection vulnerability is resolved
  7. 7. Clear any application caches if applicable
Caveat Review changelog for any template/theme changes that may require updates to custom overrides
