CVE-2025-15070
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 · uneditedExposure of Sensitive Information to an Unauthorized Actor, Missing Authorization vulnerability in Gmission Web Fax allows Authentication Abuse. This issue affects Web Fax: from 3.0 before 3.0.1
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 confidenceGmission Web Fax version 3.0 lacks proper authorization checks, allowing unauthenticated or improperly authenticated users to access sensitive information through an authentication abuse vulnerability. This missing authorization vulnerability enables unauthorized actors to bypass authentication controls and retrieve sensitive fax data.

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 installed Gmission Web Fax versionLocate the version information for your Gmission Web Fax installation. This is typically found in the application admin panel under 'About' or 'System Information', or by checking the software's built-in version display. If you have direct server access, also check any version file or metadata included with the installation.Affected if The installed version is 3.0.x where x is any version below 1 (e.g., 3.0.0) and the version is less than 4.0
-
Verify the authorization bypass is presentSince this vulnerability allows unauthenticated or improperly authenticated users to access sensitive fax data, attempt to access fax data endpoints or APIs without providing valid credentials. Review the application's authentication module configuration to confirm whether authorization checks are enforced on all sensitive endpoints.Affected if Sensitive fax data or administrative functions can be accessed without proper authentication or with manipulated authentication tokens
-
Examine access and audit logs for unauthorized accessReview Gmission Web Fax server logs and access logs for entries indicating requests to sensitive fax data from IP addresses or users without valid authentication credentials. Look for unusual access patterns, especially to fax metadata or attachment endpoints.Affected if Logs show access to fax data from unauthenticated sources or requests that bypassed the normal authentication flow
-
Check for anomalous fax data access patternsQuery the application's fax data or audit trail to identify any retrieval of fax documents or metadata by accounts that should not have authorization, or by requests lacking proper session tokens.Affected if Fax data was accessed by users or systems without documented authorization to view that specific data
You are affected if Gmission Web Fax version 3.0.0 is installed and unauthorized access to fax data can be confirmed in logs or through testing.
Generated from the published advisory. Verify against your own configuration.
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 · scoped4.0
Upgrade Gmission Web Fax to version 3.0.1 which contains the missing authorization fix. Additionally, audit access logs for any unauthorized access attempts occurring prior to the upgrade.
Web Fax 3.0.1
- 1. Identify the current installed version of Gmission Web Fax by checking the application documentation or system configuration.
- 2. If the current version is 3.0.x (where x < 1), plan for upgrade to version 3.0.1 which contains the security fix for the missing authorization vulnerability.
- 3. Before upgrading, review any release notes or change logs for version 3.0.1 to understand changes.
- 4. Perform a backup of the current Web Fax configuration and data.
- 5. Upgrade to Web Fax version 3.0.1 following the vendor's standard upgrade procedure.
- 6. After upgrade, verify the installation and test that the authorization controls are functioning correctly.
