CVE-2020-12776
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 · uneditedOpenfind Mail2000 contains Broken Access Control vulnerability, which can be used to execute unauthorized commands after attackers obtain the administrator access token or cookie.
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 confidenceOpenfind Mail2000 contains a Broken Access Control vulnerability that allows authenticated administrators to execute unauthorized system commands. The vulnerability stems from improper authorization checks after authentication, enabling privilege escalation where an attacker with valid administrator access tokens or cookies can bypass intended security restrictions to perform operations outside their authorized scope.

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 Openfind Mail2000 installationCheck the product name and version displayed in the webmail interface login page, or check the application binary/header files if accessible on the server. Look for 'Mail2000' and version number '7.0' in the UI or server files.Affected if The installed product is Openfind Mail2000 version exactly 7.0
-
Confirm administrative access existsVerify that administrator accounts or privileged user roles are configured in the system. Check user management interfaces or configuration files for accounts with elevated permissions.Affected if Administrator or privileged accounts exist in the Mail2000 system
-
Verify web interface is exposedConfirm the Mail2000 web administrative interface is accessible. Check if ports 80/443 or the webmail/admin paths are reachable and responding.Affected if The Mail2000 web interface is accessible over the network
-
Check access token/cookie handlingInspect browser developer tools or server logs for how administrative session tokens and cookies are managed during authenticated sessions. Look for session persistence mechanisms.Affected if The system uses access tokens or cookies to maintain administrator sessions
A user is affected if they have Openfind Mail2000 version 7.0 running with an accessible administrative interface and authenticated administrator sessions are handled via tokens or cookies that could be manipulated.

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 dataRemediate by implementing proper authorization validation on all administrative functions, securing access token/cookie handling with secure storage and transmission mechanisms, and adding explicit permission checks for each sensitive operation regardless of authentication status.
