CVE-2025-40713
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 · uneditedSQL 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 campo parameter in/<Client>FacturaE/BusquedasFacturasSesion.
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 confidenceSQL injection vulnerability in Quiter Gateway allows unauthenticated attackers to inject arbitrary SQL commands through the campo parameter in the BusquedasFacturasSesion endpoint. This enables complete database compromise including unauthorized data retrieval, modification, and deletion. The vulnerability affects all versions prior to 4.7.0 and rates 9.8 on the CVSS scale indicating critical severity.

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 Quiter Gateway installationLocate the Quiter Gateway application and determine its installation path or running service. Check product documentation for default installation directories or service names.Affected if The application is Quiter Gateway and its version is below 4.7.0
-
Determine installed versionCheck the installed version of Quiter Gateway by examining version files, the application web interface, or querying the service. Common methods include checking the about page, version API endpoint, or configuration files in the installation directory.Affected if The installed version is any version prior to 4.7.0
-
Verify BusquedasFacturasSesion endpoint exposureConfirm the BusquedasFacturasSesion endpoint is accessible on the application server by reviewing the web server configuration, application routing maps, or by attempting to access the endpoint via HTTP/HTTPS.Affected if The BusquedasFacturasSesion endpoint is exposed and reachable without authentication
-
Inspect application logs for SQL injection attemptsReview application and database logs for suspicious patterns in the campo parameter, looking for SQL injection signatures such as single quotes, UNION statements, OR 1=1, or other SQL meta-characters.Affected if Log analysis reveals SQL injection attempts against the campo parameter in BusquedasFacturasSesion or the endpoint is responding unexpectedly to crafted campo values
A user is affected if Quiter Gateway is installed with a version prior to 4.7.0 and the BusquedasFacturasSesion endpoint is accessible, enabling unauthenticated SQL injection through the campo parameter.

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.
dbcve · scoped4.7.0
Upgrade Quiter Gateway to version 4.7.0 or later which contains the security fix. Until patching is possible, implement web application firewall rules to block SQL injection patterns in the campo parameter.
Quiter Gateway 4.7.0
- Identify the current installed version of Quiter Gateway
- Backup the current configuration and database
- Download Quiter Gateway version 4.7.0 or later from the vendor
- Stop the Quiter Gateway service
- Install the upgrade following vendor documentation
- Restart the Quiter Gateway service
- Verify the application functions correctly
- Confirm the SQL injection vulnerability is remediated by testing the /<Client>FacturaE/BusquedasFacturasSesion endpoint with the campo parameter
