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
Documents operations, in this case "drawing", could be manipulated to contain invalid data types, possibly script code. Script code could be injected to an operation that would be executed for users that are actively collaborating on the same document. Operation data exchanged between collaborating parties does now gets checked for validity to avoid code execution. No publicly available exploits are known.

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

This is a code injection vulnerability in a document collaboration feature where malicious script code could be embedded in 'drawing' operations. When multiple users collaborate on the same document, the injected code executes in their browsers without validation of operation data types exchanged between collaborating parties.

MitigationApply the vendor patch that implements validation checks on operation data to prevent script code injection in document operations.

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 Open Xchange Appsuite installation
    Check for Open Xchange Appsuite by looking for the product installation directory (typically /opt/open-xchange or /var/opt/open-xchange) or by querying running Java processes for 'open-xchange' in the process name
    Affected if Open Xchange Appsuite is installed on the system
  2. Determine installed Appsuite version
    Locate the version file in the installation directory (commonly version.info or similar file in the Appsuite root directory) or run the vendor-provided version command if available
    Affected if The installed version is lower than 7.10.6 or equals exactly 7.10.6
  3. Check if document collaboration feature is enabled
    Examine the Appsuite configuration files (oxware.properties or similar) for settings related to document collaboration or drawing features - look for properties containing 'collaboration', 'document', or 'drawing'
    Affected if Document collaboration and drawing operations are enabled in the configuration
  4. Verify collaborative editing is accessible to users
    Check if the web interface includes document collaboration capabilities by inspecting the Appsuite web manifest or UI plugins configuration
    Affected if Users have access to collaborative document editing features

You are affected if Open Xchange Appsuite is installed with version 7.10.6 or below AND the document collaboration feature with drawing operations is enabled for users

Recommended fix High confidence

Open Xchange Appsuite 7.10.6 or later (latest 7.10.x release)

  1. 1. Identify current Open Xchange Appsuite version using the admin dashboard or version check command
  2. 2. Download the latest 7.10.x release from the official Open Xchange download portal (software.open-xchange.com)
  3. 3. Review the upgrade documentation for Appsuite at documentation.open-xchange.com
  4. 4. Perform a backup of the existing installation and database
  5. 5. Execute the upgrade following the standard Appsuite upgrade procedure
  6. 6. Verify the version shows 7.10.6 or later after upgrade
  7. 7. Test document collaboration features to confirm the fix is operational
