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
OX App Suite through 8.2 allows XSS because BMFreehand10 and image/x-freehand are not blocked.

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

OX App Suite through version 8.2 fails to block the BMFreehand10 and image/x-freehand MIME types, allowing potentially malicious content to be uploaded and served. This missing content type filter creates a cross-site scripting (XSS) vector where attackers can inject scripts through unblocked image formats.

MitigationConfigure the web application firewall or content filter to block or properly sanitize BMFreehand10 and image/x-freehand MIME types, preventing their upload and execution.

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 Open Xchange Appsuite version
    Locate the version file or use the package manager to query the installed version (e.g., 'rpm -q open-xchange-appsuite' or check /opt/open-xchange/version).
    Affected if The installed version is 7.10.5, 7.10.6, or any version from 8.2 through 8.2.323 (less than 8.2.324), or any version below 7.10.5.
  2. Confirm file upload functionality is enabled
    Verify that the web interface or API allows file uploads. Check the server configuration for 'fileUpload' or 'upload' settings, or test uploading a file through the web UI.
    Affected if File upload is permitted in the environment.
  3. Verify MIME type filtering configuration
    Inspect the content filter or MIME type whitelist/blacklist configuration files for the application. Look for entries related to 'BMFreehand10' or 'image/x-freehand' in the filter rules.
    Affected if The MIME types BMFreehand10 and image/x-freehand are not explicitly blocked or filtered, and no content sanitization is applied to these types.
  4. Check if uploaded files are served without sanitization
    Upload a test file with one of the affected MIME types (BMFreehand10 or image/x-freehand) and verify whether the server serves it with proper Content-Disposition headers or sanitization, or attempt to access the uploaded file directly.
    Affected if Uploaded files of these MIME types are served directly to users without sanitization or security headers.

You are affected if your installed Open Xchange Appsuite version falls within 7.10.5, 7.10.6, or 8.2 to 8.2.323, and file uploads with BMFreehand10 or image/x-freehand MIME types are allowed without filtering or sanitization.

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 7.10.5 / 8.2.324 or later
Fixed in 7.10.58.2.324
Interim mitigation

Configure the web application firewall or content filter to block or properly sanitize BMFreehand10 and image/x-freehand MIME types, preventing their upload and execution.

Recommended fix Moderate confidence

Open Xchange Appsuite 7.10.7+ (for 7.10.x branch) or 8.2.324+ (for 8.2.x branch)

  1. 1. Identify the current installed version of Open Xchange Appsuite using the admin console or command line tools
  2. 2. For installations on 7.10.x branch: Upgrade to version 7.10.7 or later
  3. 3. For installations on 8.2.x branch: Upgrade to version 8.2.324 or later
  4. 4. Verify the upgrade was successful by checking the version number
  5. 5. Test that the XSS vulnerability is no longer present by confirming BMFreehand10 and image/x-freehand content types are properly blocked in the configuration
Caveat Standard minor version upgrades typically do not introduce breaking changes, but review release notes for any migration notes or configuration changes
