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
SQL injection vulnerability in versions prior to 4.7.0 of Quiter Gateway by Quiter. This vulnerability allows an attacker to retrieve, create, update and delete databases through the id_concesion parameter in /<Client>FacturaE/DescargarFactura.

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

A SQL injection vulnerability exists in Quiter Gateway versions prior to 4.7.0. The vulnerability resides in the id_concesion parameter within the /<Client>FacturaE/DescargarFactura endpoint. Attackers can exploit this to inject malicious SQL queries, potentially allowing full database manipulation including retrieval, creation, update, and deletion of database records.

MitigationUpgrade to Quiter Gateway version 4.7.0 or later. As an immediate workaround, disable the affected endpoint or implement WAF rules to block SQL injection attempts in the id_concesion parameter until the upgrade can be completed.

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 Quiter Gateway installation
    Locate the Quiter Gateway installation and determine its version by checking the application binaries, configuration files, or the application's about/version information page. Common locations may include /opt/quiter/, the application web root, or the service banner if exposed.
    Affected if The installed version is any version prior to 4.7.0 (e.g., 4.6.x, 4.5.x, earlier).
  2. Verify the vulnerable endpoint exists
    Check if the /<Client>FacturaE/DescargarFactura endpoint is available in the deployed Quiter Gateway. This may require reviewing the application routing configuration, deployed WAR files, or API documentation.
    Affected if The endpoint is present and accessible in the deployed application.
  3. Confirm id_concesion parameter processing
    Inspect the application's source code, decompiled classes, or configuration to verify that the id_concesion parameter is processed by the /<Client>FacturaE/DescargarFactura endpoint without proper input sanitization or parameterized queries.
    Affected if The endpoint directly uses the id_concesion parameter value in SQL queries without prepared statements or input validation.

A user is affected if they are running any version of Quiter Gateway prior to 4.7.0 AND the /<Client>FacturaE/DescargarFactura endpoint is exposed and processes the id_concesion parameter in SQL queries without sanitization.

Upgrade available Upgrade to 4.7.0 or later
Fixed in 4.7.0
Interim mitigation

Upgrade to Quiter Gateway version 4.7.0 or later. As an immediate workaround, disable the affected endpoint or implement WAF rules to block SQL injection attempts in the id_concesion parameter until the upgrade can be completed.

Recommended fix High confidence

4.7.0

  1. 1. Identify the current version of Quiter Gateway installed by checking the application or system documentation.
  2. 2. Backup all current configurations, databases, and critical data before proceeding with the upgrade.
  3. 3. Download Quiter Gateway version 4.7.0 from the official vendor source (Quiter).
  4. 4. Follow the vendor's official upgrade instructions to install version 4.7.0, ensuring all prerequisites are met.
  5. 5. After upgrading, verify the installation was successful by checking the new version number.
  6. 6. Test the /<Client>FacturaE/DescargarFactura endpoint with the id_concesion parameter to confirm the SQL injection vulnerability is resolved.
  7. 7. Monitor system logs for any unusual database activity to ensure no exploitation occurred during the vulnerable period.
