CVE-2025-40718
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 · uneditedImproper error handling vulnerability in versions prior to 4.7.0 of Quiter Gateway by Quiter. This vulnerability allows an attacker to send malformed payloads to generate error messages containing sensitive information.
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 confidenceImproper error handling in Quiter Gateway versions prior to 4.7.0 allows attackers to send malformed payloads that trigger verbose error messages exposing sensitive system information, potentially including stack traces, file paths, or configuration details.

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 versionLocate the installed version of Quiter Gateway by checking the application binary, package manager, or startup logs where the version is typically printed on service initializationAffected if The installed version is any release prior to 4.7.0
-
Inspect error response configurationReview the Quiter Gateway configuration files or administrative interface for settings controlling error message verbosity, such as debug mode, stack trace exposure, or detailed error formatting optionsAffected if Verbose error handling is enabled and the configuration permits detailed error output to be returned to clients
-
Examine log output for sensitive detailsReview application logs, console output, or error trace files generated by Quiter Gateway to determine whether stack traces, file paths, or configuration values appear in standard error outputAffected if Logs or error messages contain stack traces, absolute file paths, environment variables, or configuration details that should not be exposed
-
Check for input validation on malformed payloadsInspect the error handling routines or middleware that processes incoming requests to verify whether malformed inputs trigger controlled error responses or leak diagnostic informationAffected if The error handling path does not sanitize or trap exceptions before returning details to the requester
You are affected if Quiter Gateway version is below 4.7.0 AND the system returns verbose error messages containing sensitive system details in response to malformed requests.

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; implement sanitized error messages that hide sensitive details while still providing useful debugging information for legitimate users.
4.7.0
- Upgrade Quiter Gateway to version 4.7.0 or later
- After upgrading, verify that error messages no longer expose sensitive information by testing with malformed payloads
- Review application logs to ensure no sensitive data was previously exposed
