CVE-2025-40719
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 · uneditedReflected Cross-site Scripting (XSS) vulnerability in versions prior to 4.7.0 of Quiter Gateway by Quiter. This vulnerability allows an attacker to execute JavaScript code in the victim's browser by sending a malicious URL trhough the id_concesion parameter in /<Client>FacturaE/VerFacturaPDF.
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 confidenceReflected Cross-site Scripting (XSS) vulnerability in Quiter Gateway versions prior to 4.7.0. The id_concesion parameter in the /<Client>FacturaE/VerFacturaPDF endpoint does not properly sanitize user input, allowing attackers to inject malicious JavaScript code that executes in victims' browsers.

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 the installed Quiter Gateway versionLocate the Quiter Gateway installation and retrieve its version number from the software metadata, configuration file, or administrative interface. Common locations include the main application directory, version info file, or system information panel.Affected if The installed version is lower than 4.7.0 (for example, 4.6.x, 4.5.x, or earlier)
-
Verify the VerFacturaPDF endpoint existsConfirm that the /<Client>FacturaE/VerFacturaPDF endpoint is present and accessible in the Quiter Gateway installation. This endpoint is part of the FacturaE module for electronic invoice processing.Affected if The endpoint is present and the version is below 4.7.0
-
Check if the id_concesion parameter accepts unsanitized inputSubmit a benign test payload (such as a simple alphanumeric string) to the id_concesion parameter in the VerFacturaPDF endpoint and observe whether the value is reflected verbatim in the response without proper encoding or sanitization.Affected if The parameter value is reflected in the response without HTML encoding or sanitization applied
A user is affected if their Quiter Gateway version is below 4.7.0 and the VerFacturaPDF endpoint with the id_concesion parameter is accessible without proper input sanitization.

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 to Quiter Gateway version 4.7.0 or later, which contains the security patch for this vulnerability. If immediate upgrade is not possible, implement output encoding for the id_concesion parameter in the affected endpoint.
4.7.0
- Identify the currently installed version of Quiter Gateway
- Backup the current Quiter Gateway installation and configuration
- Review Quiter release notes for version 4.7.0 to confirm security fixes
- Schedule upgrade during a maintenance window
- Upgrade Quiter Gateway to version 4.7.0 or later
- Verify the upgrade was successful by checking the installed version
- Test that the /<Client>FacturaE/VerFacturaPDF endpoint with the id_concesion parameter functions correctly
