CVE-2024-5400
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 does not properly filter parameters of specific CGI. Remote attackers with regular privileges can exploit this vulnerability to execute arbitrary system commands on the remote server.
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 command injection vulnerability in its CGI component where specific parameters are not properly filtered. An authenticated attacker with regular user privileges can inject arbitrary system commands through these unsanitized CGI parameters, achieving remote code execution on the affected server.

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.
-
Confirm Openfind Mail2000 installationLocate Mail2000 installation directory or check for running processes related to mail2000 (e.g., look for mail2000 processes, check for /mail2000 web path, or query installed software on the server)Affected if Mail2000 is found to be installed on the system
-
Identify installed Mail2000 versionCheck version information in Mail2000 installation files, configuration files, or web interface (commonly found in about page, version file, or registry entries depending on OS)Affected if Installed version matches 6.0, 7.0, or 8.0 exactly
-
Verify CGI component is enabledCheck Mail2000 configuration files or web server settings for CGI module/script execution status (look for cgi-bin, .cgi settings, or Mail2000 CGI configuration)Affected if CGI execution is enabled for Mail2000 web interface
-
Inspect CGI parameter handlingReview Mail2000 CGI scripts and their parameter processing (examine CGI binaries in mail2000 cgi-bin directory, check how user input is passed to system calls)Affected if CGI parameters are passed to shell commands without proper sanitization or parameterized queries
-
Check authentication settingsReview Mail2000 user authentication configuration and privilege settings (check user role definitions in Mail2000 admin panel or configuration)Affected if Regular (non-admin) user accounts can access CGI functionality
Environment is affected if Openfind Mail2000 versions 6.0, 7.0, or 8.0 are installed with CGI component enabled, allowing authenticated regular users to execute arbitrary commands via unsanitized CGI parameters.

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 strict input validation and parameterized queries for all CGI parameters. Alternatively, restrict CGI execution privileges and deploy WAF rules to block suspicious command injection patterns until vendor patches are available.
