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 · unedited
Use of GET Request Method With Sensitive Query Strings vulnerability in Apache OpenMeetings. The REST login endpoint uses HTTP GET method with username and password passed as query parameters. Please check references regarding possible impact This issue affects Apache OpenMeetings: from 3.1.3 before 9.0.0. Users are recommended to upgrade to version 9.0.0, which fixes the issue.

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 confidence

The REST login endpoint in Apache OpenMeetings uses HTTP GET method with username and password transmitted as URL query parameters. This exposes credentials in server logs, browser history, proxies, and network monitoring, as GET requests are inherently less secure for sensitive data transmission.

MitigationUpgrade to Apache OpenMeetings version 9.0.0 which implements proper POST-based authentication for the login endpoint.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Apache OpenMeetings installation and version
    Locate the OpenMeetings installation directory and check the version file or war file name. Common locations include /opt/openmeetings, /usr/share/openmeetings, or the application server webapps directory. Look for a version manifest, pom.xml, or the war file name containing the version number.
    Affected if The installed version is >= 3.1.3 and < 9.0.0
  2. Locate the REST login endpoint configuration
    Search the OpenMeetings configuration files for REST API endpoint definitions. Look in conf/ or config directories for files like rest-config.xml, web.xml, or annotations defining the /login or /user/login endpoint.
    Affected if The REST login endpoint is enabled and accessible at the default path /openmeetings/services/user/login or similar REST paths
  3. Test the REST login endpoint for GET method acceptance
    Send a GET request to the login endpoint with username and password as query parameters, for example: curl -k 'https://<server>/openmeetings/services/user/login?username=user&password=pass'. Observe if the server responds with success or processes the request.
    Affected if The endpoint accepts GET requests and processes credentials from query parameters (returns 200 OK or authentication success)
  4. Examine server access logs for credential exposure
    Review HTTP access logs from the web server (Apache HTTP, Nginx) or application server (Tomcat, Jetty) that fronts OpenMeetings. Search for GET requests to the login endpoint containing 'username=' and 'password=' in the URL.
    Affected if Plaintext credentials appear in access logs as part of the request URL query string

You are affected if Apache OpenMeetings version 3.1.3 through 8.x is installed and the REST login endpoint is accessible, as it will accept credentials via GET request parameters that get logged in plain text.

Upgrade available Upgrade to 9.0.0 or later
Fixed in 9.0.0
Interim mitigation

Upgrade to Apache OpenMeetings version 9.0.0 which implements proper POST-based authentication for the login endpoint.

Recommended fix High confidence

9.0.0

  1. 1. Backup all OpenMeetings data, configuration files, and database
  2. 2. Review the release notes for version 9.0.0 to understand any configuration or migration requirements
  3. 3. Download Apache OpenMeetings version 9.0.0 from the official Apache distribution (https://openmeetings.apache.org)
  4. 4. Stop the current OpenMeetings service
  5. 5. Install version 9.0.0 following the official upgrade instructions
  6. 6. Start the OpenMeetings service
  7. 7. Verify the login endpoint now uses POST method instead of GET for sensitive credentials
  8. 8. Test login functionality to ensure the application works correctly after upgrade
Caveat Major version upgrade from 3.x to 9.x may introduce breaking changes; review release notes for migration steps and deprecated features
