CVE-2000-0056
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 · uneditedIMail IMONITOR status.cgi CGI script allows remote attackers to cause a denial of service with many calls to status.cgi.
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 confidenceThe IMail IMONITOR status.cgi CGI script contains a denial-of-service vulnerability where remote attackers can cause service disruption through repeated or multiple simultaneous requests to the script, likely due to improper resource management or lack of request throttling.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Imail installation and versionCheck for Imail installation directories and locate version information in registry or version files (commonly in Program Files/Ipswitch or similar). Compare the installed version against 5.0.8, 6.0, and 6.1.Affected if Installed version matches 5.0.8, 6.0, or 6.1
-
Verify IMONITOR component is installedCheck for the presence of IMONITOR component within the Imail installation. Look for IMONITOR directories or check service/feature lists.Affected if IMONITOR component is installed alongside the affected Imail versions
-
Locate status.cgi scriptSearch for status.cgi in CGI script directories within the Imail web server components (commonly under IMONITOR or web directories).Affected if status.cgi script exists in the IMONITOR CGI directory
-
Confirm IMONITOR web interface accessibilityTest if the IMONITOR web interface is accessible by attempting to reach status.cgi via HTTP/HTTPS (e.g., /imonitor/status.cgi). Check web server configuration for CGI execution permissions.Affected if IMONITOR web interface and status.cgi are accessible over the network without authentication restrictions
User is affected if running Imail versions 5.0.8, 6.0, or 6.1 with the IMONITOR component installed and the status.cgi script accessible, as repeated requests to this CGI can trigger denial of service.

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 dataDisable or remove the vulnerable status.cgi script if IMONITOR is not required, or implement web application firewall rules to rate-limit requests to CGI scripts; for long-term remediation, migrate to a supported mail server solution as IMail is end-of-life.
