CVE-2020-12106
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 · uneditedThe 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 confidenceThe 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.

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 the VPNCrypt M10 firmware versionAccess the device administrative interface or check the system information page to confirm the installed firmware version is exactly 2.6.5Affected if The firmware version displayed is 2.6.5
-
Locate the web portal interfaceDetermine the IP address of the VPNCrypt M10 device and access its web-based management interface via HTTP/HTTPS on the typical administration portsAffected if The web portal is accessible over the network
-
Test unauthenticated access to administrative POST endpointsUsing 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 tokensAffected if The POST requests are accepted and processed without requiring any authentication
-
Verify credential change functionalitySubmit a crafted POST request to the endpoint responsible for changing administrator passwords without authentication and observe whether the device accepts and processes the requestAffected if The device allows password changes without any authentication validation
-
Check network accessibility of the web portalDetermine whether the web management interface is exposed to untrusted networks or the internet, rather than being restricted to a trusted management VLANAffected 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.

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.
From vendor dataImplement 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.
