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
SOCIFI Socifi Guest wifi as SAAS wifi portal is affected by Insecure Permissions. Any authorized customer with partner mode can switch to another customer dashboard and perform actions like modify user, delete user, etc.

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 confidence

SOCIFI Guest WiFi SaaS platform has a broken access control vulnerability in its partner mode functionality. The authorization logic fails to properly validate that a partner-mode user can only access resources within their own customer account, allowing authenticated users to switch to other customer dashboards and perform privileged actions like modifying or deleting users in those accounts.

MitigationImplement proper authorization checks ensuring partner-mode users can only access resources within their assigned customer account, validate user permissions before executing any action on resources, and enforce strict session isolation between customer tenants.

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 if partner mode functionality exists
    Locate and inspect the partner mode feature in the SOCIFI Guest WiFi platform. Check for partner-facing APIs, dashboards, or user roles that provide multi-tenant customer management capabilities.
    Affected if Partner mode functionality is present and accessible in the deployment
  2. Verify partner user role assignment
    Enumerate all user accounts and identify those assigned the partner or equivalent elevated role. Check which customer account each partner user is associated with in the user database or directory.
    Affected if There are users with partner-level privileges assigned to specific customer accounts
  3. Test cross-customer dashboard access
    Log in as a partner-mode user assigned to one customer account. Attempt to directly access or switch to a different customer account dashboard via URL manipulation, API endpoints, or dashboard navigation parameters.
    Affected if A partner user can view or access the dashboard, data, or interface of a customer account other than the one they are assigned to
  4. Test unauthorized privileged actions on other tenants
    While logged in as a partner user for one customer, attempt to perform privileged actions (create, modify, delete users) on a different customer account either through API calls or the web interface.
    Affected if Partner users can modify, delete, or create users in customer accounts outside their assigned tenant
  5. Review authorization validation logs
    Examine application and API logs for requests where the authenticated partner user ID does not match the customer account ID being accessed. Look for authorization bypass indicators.
    Affected if Logs show partner users successfully accessing resources or performing actions on customer accounts they are not assigned to

The environment is affected if partner mode functionality exists and allows authenticated partner users to access or modify resources in customer accounts other than the one they are assigned to.
