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
An attacker who has gained access to an admin account can perform RCE via null-byte injection Vendor: The Apache Software Foundation Versions Affected: Apache OpenMeetings from 2.0.0 before 7.1.0

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 confidence

Apache OpenMeetings versions 2.0.0 before 7.1.0 allow remote code execution through null-byte injection. An authenticated administrator can inject null bytes into input fields (likely file paths or parameters), bypassing security checks and executing arbitrary commands on the host system.

MitigationUpgrade Apache OpenMeetings to version 7.1.0 or later. Until patched, limit admin account access and monitor for suspicious admin activity.

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 the installed Apache OpenMeetings version
    Locate the version file or check the admin dashboard for the current version number, typically visible in the login page footer or about section
    Affected if The installed version is 2.0.0 or higher but lower than 7.1.0
  2. Confirm admin account availability
    Check whether any administrator accounts have been created or provisioned in the OpenMeetings system
    Affected if An authenticated administrator account exists in the system, which is required to exploit this vulnerability
  3. Examine application logs for null-byte injection attempts
    Review web server or OpenMeetings application logs for patterns containing null bytes (represented as %00 or \x00) in request parameters, particularly in file upload or path-related fields
    Affected if Log entries show null-byte injection patterns in requests from admin-level sessions
  4. Assess network exposure of the admin interface
    Determine if the OpenMeetings administrative interface is accessible from untrusted networks or the internet
    Affected if The admin panel is exposed beyond trusted network boundaries, increasing exploitability risk

You are affected if your OpenMeetings installation is version 2.0.0 or later but earlier than 7.1.0 and has an active administrator account that could be leveraged for null-byte injection attacks.

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.

Upgrade available Upgrade to 7.1.0 or later
Fixed in 7.1.0
Interim mitigation

Upgrade Apache OpenMeetings to version 7.1.0 or later. Until patched, limit admin account access and monitor for suspicious admin activity.

Recommended fix High confidence

7.1.0 or later

  1. Verify current Apache OpenMeetings version by checking the administration interface or installation directory
  2. Backup the existing OpenMeetings database and configuration files before upgrading
  3. Download Apache OpenMeetings version 7.1.0 or later from the official Apache repository (https://openmeetings.apache.org)
  4. Stop the currently running OpenMeetings service
  5. Install the new version (7.1.0 or later) following the standard upgrade procedure from the Apache OpenMeetings documentation
  6. Start the upgraded OpenMeetings service
  7. Verify the installation was successful and the service is running properly
