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
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache OpenMeetings. This issue affects Apache OpenMeetings: from 5.0.0 before 9.1.0. An attacker with moderator rights in any room can read arbitrary files accessible to the OS account running the OM server, including credentials and secrets, via a crafted download request. Users are recommended to upgrade to version 9.1.0, 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

A path traversal vulnerability in Apache OpenMeetings allows authenticated users with moderator privileges to craft malicious download requests using '..' sequences to escape the intended directory and read arbitrary files on the server, including sensitive credentials and secrets.

MitigationUpgrade Apache OpenMeetings to version 9.1.0 or later to resolve this vulnerability.

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. Determine installed Apache OpenMeetings version
    Locate the version file or check the admin dashboard for the installed version number
    Affected if Installed version is >= 5.0.0 and < 9.1.0
  2. Identify users with moderator privileges
    Review user accounts and role assignments in the OpenMeetings admin panel or user database to determine which accounts have moderator access
    Affected if Any user account holds moderator privileges in the system
  3. Verify if download functionality is exposed
    Check if the file download endpoint is accessible on the OpenMeetings server - look for download-related API routes or web endpoints
    Affected if The download endpoint is reachable without additional access restrictions beyond authentication
  4. Confirm moderator-level authentication is possible
    Test whether a user with moderator privileges can authenticate to the OpenMeetings API or web interface
    Affected if Moderator accounts can successfully authenticate to the system

A user is affected if their OpenMeetings installation version is between 5.0.0 and 9.1.0 and they have at least one active moderator account that can access the download functionality.

Upgrade available Upgrade to 9.1.0 or later
Fixed in 9.1.0
Interim mitigation

Upgrade Apache OpenMeetings to version 9.1.0 or later to resolve this vulnerability.

Recommended fix High confidence

9.1.0

  1. 1. Plan and schedule an upgrade to Apache OpenMeetings version 9.1.0
  2. 2. Back up your current OpenMeetings installation, database, and configuration files before proceeding
  3. 3. Review the release notes for version 9.1.0 for any specific migration or configuration requirements
  4. 4. Download Apache OpenMeetings version 9.1.0 from the official Apache source (downloads.apache.org)
  5. 5. Stop the currently running OpenMeetings service
  6. 6. Install version 9.1.0 following standard upgrade procedures (replace existing files or use the upgrade method documented for your deployment
  7. 7. Start the OpenMeetings service and verify the application is running correctly
  8. 8. Test that the path traversal vulnerability is remediated by attempting a download with the vulnerable pattern (should be blocked in 9.1.0)
Caveat Review release notes between your current version and 9.1.0; major version upgrades may include breaking changes to APIs, plugins, or configuration formats
