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
Authorization Bypass Through User-Controlled Key vulnerability in Software Engineering Consultancy Machine Equipment Limited Company Hearing Tracking System allows Authentication Abuse. This issue affects Hearing Tracking System: before for IOS 7.0, for Android Latest release 1.0.

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 confidence

The vulnerability is an Authorization Bypass Through User-Controlled Key in the Hearing Tracking System mobile application. Attackers can manipulate a user-controlled key parameter (likely an object reference or session identifier) to bypass authentication checks and gain unauthorized access to other users' data or administrative functions.

MitigationImplement proper server-side authorization checks that validate user permissions for every request, avoid relying on user-supplied keys for authorization decisions, and use indirect object references with proper session validation.

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 the installed app version
    Open the Simgesel Hearing Tracking System mobile app, navigate to Settings or About section, and record the version number displayed. On Android, you can also check in Settings > Apps > Hearing Tracking System. On iOS, check in Settings > General > iPhone Storage if the app is installed.
    Affected if The displayed version is less than 7.0 (or shows version 1.0 or lower)
  2. Verify the mobile app is communicating with a backend server
    Configure a network proxy (such as Burp Suite, OWASP ZAP, or Charles Proxy) on a test device to intercept HTTPS traffic from the app. Launch the app and perform typical operations like logging in, viewing hearing data, or accessing user profiles.
    Affected if The app transmits user identifiers, session tokens, or object references in API request parameters that could be manipulated
  3. Check for user-controlled key parameters in API requests
    In the intercepted traffic, examine POST/GET requests for parameters that appear to be direct object references, user IDs, record IDs, or session identifiers. Note any endpoints where these values are sent in plain text or easily guessable formats.
    Affected if Requests contain parameters like user_id, record_id, session_key, or similar identifiers that are controllable by the user and used for authorization decisions
  4. Test for authorization bypass
    Using the intercepted requests, modify a user-controlled key parameter (such as changing a user_id or record_id to another value) and replay the request to see if the server returns data belonging to a different user or allows access to unauthorized functions.
    Affected if The server returns successful responses with data from other users or allows access to functions the current user should not have when key parameters are modified

A defender is affected if the installed Simgesel Hearing Tracking System version is below 7.0 (or version 1.0 or lower) and the app transmits controllable key parameters that can be manipulated to access other users' data.

dbcve · scoped
Upgrade available Upgrade to 7.0 or later
Fixed in 7.0
Interim mitigation

Implement proper server-side authorization checks that validate user permissions for every request, avoid relying on user-supplied keys for authorization decisions, and use indirect object references with proper session validation.

Recommended fix Moderate confidence

iOS: version 7.0 or later; Android: latest version subsequent to 1.0

  1. 1. Identify the Hearing Tracking System application installed on iOS or Android devices
  2. 2. For iOS users: Check the current application version in the App Store or device settings
  3. 3. For iOS users: Update the Hearing Tracking System app to version 7.0 or later from the Apple App Store
  4. 4. For Android users: Check the current application version in the Google Play Store or device settings
  5. 5. For Android users: Update the Hearing Tracking System app to the latest available version (subsequent to 1.0) from Google Play Store
  6. 6. After updating, verify the application functions correctly and test that the authorization bypass vulnerability is no longer exploitable
Caveat Users should test core functionality (hearing tracking features) after upgrade to ensure compatibility with the new version
