CVE-2000-0632
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 · uneditedBuffer overflow in the web archive component of L-Soft Listserv 1.8d and earlier allows remote attackers to execute arbitrary commands via a long query string.
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 confidenceA buffer overflow vulnerability exists in the web archive component of L-Soft Listserv version 1.8d and earlier. The flaw is triggered by sending an excessively long query string to the web archive, which overflows a buffer and enables remote attackers to execute arbitrary commands on the target system.

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 Listserv versionLocate the Listserv installation directory and check the version file or executable properties. Common locations include /opt/listserv or C:\LISTSERV on Windows. Look for version information in the main executable, README, or version.txt file.Affected if The installed version is 1.8c or 1.8d (or any version 1.8d and earlier)
-
Confirm web archive component is enabledCheck the Listserv configuration files (typically listmaster.ini or config file in the Listserv root) for web archive settings. Look for parameters like WA or WEBARCHIVE, or check if the 'wa' or 'webarch' module is loaded.Affected if The web archive component is configured and active in the Listserv setup
-
Verify web server is runningCheck if Listserv's built-in web server or attached web server (such as the L-Soft w3md.exe or external web server serving Listserv's CGI scripts) is currently running and accepting connections.Affected if The web interface is exposed and accessible, making the vulnerable component reachable over the network
-
Inspect for exploitation attemptsReview Listserv's web archive access logs (typically in a /logs or /archive/logs directory) for unusually long query strings or patterns indicative of buffer overflow testing. Also check system logs for any unexpected commands or processes.Affected if Logs show long query strings (typically hundreds or thousands of characters) sent to the web archive CGI or script, or unexpected command execution on the server
A system is affected if L-Soft Listserv version 1.8c or 1.8d is installed with the web archive component enabled and accessible, regardless of whether exploitation has occurred.

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 dataUpgrade L-Soft Listserv to a version beyond 1.8d that includes the security patch. If immediate upgrading is not feasible, disable or restrict network access to the web archive component until the upgrade can be performed.
