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
The Web portal of the WiFi module of VPNCrypt M10 2.6.5 allows unauthenticated users to send HTTP POST request to several critical Administrative functions such as, changing credentials of the Administrator account or connect the product to a rogue access point.

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

The WiFi module web portal in VPNCrypt M10 version 2.6.5 lacks authentication enforcement on critical administrative POST endpoints, allowing any unauthenticated user to invoke functions that change Administrator credentials or configure access point connections. This is a direct unauthenticated privilege escalation vulnerability in the device's REST API.

MitigationImplement mandatory authentication and authorization checks on all administrative endpoints, ideally requiring session tokens or HTTP Basic/Digest authentication. If no vendor patch exists, restrict network access to the web portal via firewall rules or VLAN segmentation.

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 VPNCrypt M10 firmware version
    Access the device administrative interface or check the system information page to confirm the installed firmware version is exactly 2.6.5
    Affected if The firmware version displayed is 2.6.5
  2. Locate the web portal interface
    Determine the IP address of the VPNCrypt M10 device and access its web-based management interface via HTTP/HTTPS on the typical administration ports
    Affected if The web portal is accessible over the network
  3. Test unauthenticated access to administrative POST endpoints
    Using a tool like curl or Burp Suite, send a POST request to the device's administrative endpoints (such as those handling administrator credential changes or access point configuration) without providing any authentication credentials or session tokens
    Affected if The POST requests are accepted and processed without requiring any authentication
  4. Verify credential change functionality
    Submit a crafted POST request to the endpoint responsible for changing administrator passwords without authentication and observe whether the device accepts and processes the request
    Affected if The device allows password changes without any authentication validation
  5. Check network accessibility of the web portal
    Determine whether the web management interface is exposed to untrusted networks or the internet, rather than being restricted to a trusted management VLAN
    Affected if The administrative web portal is reachable from an untrusted network segment

Your environment is affected if you are running VPNCrypt M10 firmware version 2.6.5 and the web portal administrative POST endpoints accept unauthenticated requests to change credentials or configure network settings.
