CVE-2017-7683
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 · uneditedApache OpenMeetings 1.0.0 displays Tomcat version and detailed error stack trace, which is not secure.
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 confidenceApache OpenMeetings 1.0.0 exposes Tomcat version information and detailed error stack traces through error pages, allowing attackers to gather intelligence about the system infrastructure and potentially identify vulnerable components.
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 Apache OpenMeetings installationLocate the OpenMeetings web application in your environment - typically deployed as a WAR file or standalone installation under the web server document rootAffected if OpenMeetings is present on the system
-
Determine installed OpenMeetings versionCheck the version of the installed Apache OpenMeetings instance - this is usually displayed on the login page, in the application header, or in the about/admin section of the applicationAffected if The installed version matches one of the affected versions: 1.0.0, 2.0, 2.1, 2.1.1, 2.2.0, 3.0.0, 3.0.1, 3.0.2, 3.0.3, 3.0.4, 3.0.5, or 3.0.6
-
Trigger an error condition to observe responseSend a malformed request to the OpenMeetings server (such as requesting a non-existent page, submitting invalid input, or causing an application error) and capture the HTTP responseAffected if The error response contains detailed Java stack traces, exception messages, or internal framework details
-
Inspect HTTP response headers for version disclosureUse a tool like curl with the -I flag to examine the HTTP response headers returned by the serverAffected if The Server header or other headers disclose the Tomcat version number
-
Check server error page configurationExamine the Tomcat server configuration files (typically server.xml) and the web.xml deployment descriptor for custom error handler mappingsAffected if Custom error handlers are not configured or are set to show verbose error pages instead of generic messages
You are affected if Apache OpenMeetings versions 1.0.0 through 3.0.6 are installed AND error responses expose stack traces or Tomcat version information in headers or pages.

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 dataConfigure custom error handlers to suppress stack traces and disable server version disclosure in Tomcat server configuration.
