CVE-2016-0322
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 · uneditedCross-site scripting (XSS) vulnerability in IBM Connections 4.0 through CR4, 4.5 through CR5, 5.0 through CR4, and 5.5 before CR1 allows remote authenticated users to inject arbitrary web script or HTML by uploading an HTML document.
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 confidenceStored XSS vulnerability in IBM Connections allows authenticated users to inject arbitrary JavaScript/HTML by uploading malicious HTML documents. When other users access these uploaded files, the embedded scripts execute in their browsers, enabling session hijacking, credential theft, or defacement.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed IBM Connections versionCheck the product version through the IBM Connections administration console or by examining the version.info file in the installation directory. Common paths include /opt/IBM/Connections/version.info or through the wsadmin utility.Affected if The installed version matches 4.0.0.0, 4.5.0.0, 5.0.0.0, or 5.5.0.0, or any version within these release families.
-
Confirm file upload functionality is enabledVerify whether the Files or Communities application, which handles document uploads, is enabled in your IBM Connections deployment. Check through the IBM Connections Administration console or via wsadmin commands.Affected if The Files or Communities application is enabled and permits users to upload files.
-
Inspect HTTP response headers for HTML file servingCapture network traffic or examine server configuration when an HTML file is accessed. Check if the Content-Disposition header is set to 'attachment' for .html, .htm, or other HTML file types uploaded to the system.Affected if HTML files are served with Content-Type text/html (or no Content-Disposition header) rather than Content-Disposition: attachment, allowing the browser to render them.
-
Review HTML content sanitization configurationExamine the IBM Connections configuration files (such as LotusConnections-config.xml) and any associated HTML sanitization or sandbox settings. Check if a sandboxing mechanism or HTML sanitizer is configured for uploaded content.Affected if No HTML sanitization, sandboxing, or content filtering is configured for uploaded HTML documents.
-
Audit existing uploaded HTML documentsSearch the file repository or database for .html, .htm, or other HTML file extensions that may have been uploaded by users. Inspect their contents for suspicious script tags, iframes, or event handlers.Affected if Any HTML files exist in the system that contain embedded JavaScript, iframe tags, or other potentially malicious content.
You are affected if your IBM Connections version is 4.0.0.0, 4.5.0.0, 5.0.0.0, or 5.5.0.0, and HTML file uploads are permitted without Content-Disposition: attachment headers or HTML 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.
From vendor dataImplement Content-Disposition: attachment header for HTML uploads, or sanitize/sandbox HTML content before serving to prevent script execution. Apply the vendor patch (CR1 for v5.5 or later) if available.
